I just saw India airlift a large oxygen tank from Singapore. Is it difficult to manufacture it? India does not have the ability to manufacture, or is it because it is too late to manufacture? Or other reasons?
The rapid increase in confirmed cases has caused hospitals everywhere to face the exhaustion of medical resources such as hospital beds, medical oxygen and ventilators. In order to alleviate the shortage of medical resources, the Indian government has adopted a series of measures, including increasing the production and supply of medical oxygen. The soaring demand for medical oxygen has caused long queues in front of oxygen production companies, and it has also made oxygen production companies feel overwhelmed.
In response to the shortage of medical oxygen, the Indian government has launched a number of actions. The Indian railway transportation department has stepped up the opening of express trains to deliver oxygen tanks to all parts of the country. According to Indian media statistics on the 24th, in the past 24 hours, the Indian Railways have transported nearly 150 tons of medical oxygen to the whole country.
Due to high demand and short supply, many oxygen plants have been overwhelmed. In front of an oxygen plant in Lucknow, the capital of Uttar Pradesh, India, many medical staff, community workers and ordinary citizens lined up outside the plant with empty oxygen tanks.

The current production line for hypoxia is too late. It will take about a year for the whole set of things to be built and adjusted. When the outbreak broke out in Wuhan last year, the oxygen consumption was ten times longer in a short period of time, but. . . Next to it is Wuhan Iron and Steel. All large-scale steel plants supporting oxygen production have their production capacity far greater than medical needs. It is not difficult to transfer purification and filtration to medical use. The bottleneck may occur. Instead, the hardware level of the hospital. Considering China’s steel production capacity, even if the whole country breaks out There will be no shortage of oxygen itself. India’s industrialization is obviously not feasible, so large oxygen tanks are required for deployment, transportation and storage, but where industrialization is not feasible, it is usually not easy to build so many large tanks. Moreover, the Indian central government controls local energy capacity. Very poor, local development is uneven. For the national epidemic, with cans and oxygen, it may not be able to solve any problems.

Kerala, the state with the largest production capacity in India, has a medical oxygen production capacity of about 200 tons per day under normal circumstances. Now it has urgently expanded its production capacity to over 300 tons. So far, India needs more than 8,000 tons of medical oxygen per day, and the total production capacity is only 7,100 tons including industrial oxygen, which is a difference of 1,000 tons. India has approved a construction plan with a budget of 20 billion rupees and is expected to increase the production capacity of medical oxygen by 1,540 tons. This number is currently sufficient, but it is hard to tell if the epidemic in India continues to develop. Moreover, it takes time from investment and construction to production and use, and it takes half a year at the earliest. As we all know, the time in India is different from the time in China. The Indians say that 5 minutes is equivalent to the Chinese say two hours, and the Indians say that two hours are equivalent to the Chinese saying the day after tomorrow. This half year refers to Chinese time or Indian time. I do not know. It’s not enough to have oxygen. You have to have a container, you have to have transportation, and you have to have oxygen supply equipment. The current situation in India is that there is a shortage of everything. There is no surplus of oxygen tanks, oxygen cylinders, oxygen transport vehicles, oxygen pipes, oxygen masks, etc. Even hospital beds and coffins are not enough. So the book returns to the subject: Is it difficult to make large oxygen tanks in India? Oxygen tanks are not difficult to build, and large oxygen tanks can also be built in India. But there are so many things that India needs to make now, and it is impossible to make it. In addition, the Indian government’s bureaucracy is particularly bloated, decadent and inefficient. It has always been a headache, and it has never been forward-looking or planned. They didn’t expect that the oxygen gap would be so large before, and then they spent a lot of effort to increase the oxygen production capacity. After the oxygen production capacity came up, it was discovered that there were not enough containers. It’s too late to build an oxygen tank, so of course you have to hurry up and buy it. This kind of thing is that you can’t keep up with one step, and you can even say that it is a chain reaction, a vicious circle, and the more complicated and chaotic things become, they will be caught off guard. Naturally, the Indian show operation will be more popular in the future. Just get used to it.

Xie no one invited me, a professional athlete of “oxygen production”, to answer. Before answering the question, let’s clarify 2 knowledge points. Knowledge point 1: Commonly used medical oxygen supply sources include medical liquid oxygen supply sources, medical oxygen busbar supply sources and medical molecular sieve oxygen generator supply sources. For example, what India transports by air from Singapore is medical liquid oxygen, and what is urgently purchased from China is medical molecular sieve oxygen generators… Therefore, currently India is not having great difficulties in manufacturing oxygen cylinders, but facing the entire oxygen supply system. collapse. Knowledge point 2: Oxygen is divided into industrial grade and medical grade. Industrial oxygen quality requirements are relatively low, and the oxygen concentration is above 99%, which is qualified. There will be carbon monoxide, carbon dioxide, acetylene and other impurities that are extremely harmful to the human body. The oxygen content of medical oxygen shall not be less than 99.5%. Hypoxia in India is a public incident that broke out long ago. The collapse of the oxygen production system occurred in October last year: a key and main reason at that time was that in order to force the resumption of work and production, India diverted 50% of the oxygen. Industry, leading to a serious shortage of medical oxygen. One of the major tests of the medical industry is strategic urgency. In a state of emergency, it is no longer possible to consider “whether it can be done” from a purely technical level, but to examine the maturity of the industry from the entire industrial chain of capital, manpower, production capacity, hardware, raw materials, storage, and transportation. Of course, from an objective point of view, the supply of oxygen is a problem that has been overlooked for a long time, especially in low- and middle-income countries. For example, the reserve levels of ventilators and oxygen generators have also been greatly improved after the new crown, which is also true in European and American countries. Due to the limited oxygen supply and distribution network, and the hospital’s oxygen supply system, due to the original design, is not enough to cope with the influx of patients with a large-scale respiratory epidemic, this will further test the national power and organizational strength behind it. In countries with a solid industrial foundation and strong mobilization capabilities, although the problem of hypoxia has been briefly exposed, it can be resolved quickly. This is not just China. From this perspective, I will answer the question: Is it difficult to manufacture large oxygen tanks in India? difficult. Fortunately, during the severe period of domestic hypoxia in 2020, I have made contributions to the motherland. This is the eternal Medal of Honor of Yuyue Medical.

Since last year, due to the growth of exports, it is difficult to find a container. Container manufacturers, such as China, concentrate on shipping, and production orders are basically full. This situation has continued from last year to this year. As far as I know, these manufacturers still have a certain degree of expansion. They have modified their factories and added some production lines. Why don’t they expand their production on a larger scale? I think that because expansion requires new factories, equipment purchases, and new manpower, but the epidemic has passed in one or two years. Once the epidemic has passed, if the demand falls back to before the epidemic, the new factories and equipment may be idle. In the industrial manufacturing sector, depreciation is generally calculated based on at least 10 years. The two years are over, and the input costs have not been recovered. Unless the price rises, a little increase is OK, but too much increase is obviously not realistic. India’s oxygen tank is also the same problem. It is certainly possible to manufacture it. However, to expand production capacity, investment is required. After the epidemic is over, these inputs are estimated to be in vain. Of course, they can sell oxygen tanks at sky-high prices, but only in India. People’s current income situation has risen too much and they can’t afford it, and no one will do this kind of uneconomical business. Therefore, some of the benefits of state-owned enterprises are reflected at this time. During the epidemic, everything is to serve the epidemic. The state has ordered that state-owned enterprises must resolutely, immediately and unconditionally implement them immediately, regardless of benefits and costs. This is something that private companies don’t have. Therefore, the manufacture of large oxygen tanks in India is actually not a problem of manufacturing capacity or technology, but a capital problem. Supplementary data: In terms of performance data, the container segment of CIMC will achieve operating income of 22.164 billion yuan in 2020, an increase of 9.92% year-on-year, and net profit of 1.987 billion yuan for the year. The net profit margin has reached the highest level in recent years. Due to the impact of the epidemic in the first and second quarters of 2020, the recovery reached such a level in the third quarter, which shows how busy CIMC container sector is in the second half of the year.

Gao Zan is right. In fact, with the steel production in India, oxygen is absolutely indispensable. The oxygen purity of the air separation plant supporting the steel plant can reach 99.6%. With only one set of GOX80000, it can be 80,000 cubic meters of pure oxygen per hour. . As long as you have the ability to pretend to go, the amount of medical care is just drizzle. My current company is an air separation plant, and there are many projects in India. According to our overseas colleagues, since the Sino-Indian relations turned cold, our debugging and project personnel, Indians have not issued visas for a long time, and debugging can only hang skype video remotely. The point is that now in the air separation industry, if you don’t look for Chinese, you can only go to Linde in Germany. Their response is not so fast. Low-temperature pressure vessels for liquid oxygen are not so easy to manufacture. The relevant national standard is about the same thickness as Cihai. Besides, the exported products may also meet the ASME standard according to customer requirements…. How can we make a batch of these tanks? It will take two to three months. Then you can only buy a ready-made oxygen tank from the gas head.

Industrial oxygen, literally interpreted as oxygen used in industrial production and product processing, has low quality requirements, and generally requires a purity of more than 99% to be qualified. The industry implements the national recommended standards, and the only indicators tested are oxygen content and moisture content. The so-called national recommended standards are relative to the national mandatory standards. Mandatory standards are required by the state to implement administrative orders and laws that require relevant departments and units and even individuals to implement them; while the recommended standards are market-oriented and encourage companies Voluntary adoption can not be implemented, but it may affect economic benefits, which is the country’s minimum requirement for enterprises. This paved the way for industrial oxygen to flow outside of the field. This may be an institutional loophole. It is time to upgrade the recommended standards that have been in use for nearly two decades. When they become mandatory standards, the majesty of the law will be further strengthened and the fluke psychology of production enterprises will be eliminated. Medical oxygen is oxygen for clinical medical use, commonly known as dry oxygen, which is mainly used to prevent and treat patients with hypoxia, such as respiratory muscle paralysis, drowning, and shock caused by carbon monoxide. Medical oxygen has high purity, colorless, odorless, and no harmful impurities. It is a special commodity in circulation. In 1988, the State Bureau of Technical Supervision issued a national mandatory standard for medical oxygen. But medical oxygen is not only a commodity, but also a medicine. The 2000 edition of the “Chinese Pharmacopoeia” included the medicinal standards for medical oxygen, and implemented the drug approval number and license management system for its production. The 2005 edition of the “Chinese Pharmacopoeia” stipulates mandatory national standards for medical oxygen. The gaseous and liquid oxygen produced by the separation of air by the cryogenic method (also called cryogenic method) is used to determine the test items, including oxygen content and moisture content. , Carbon dioxide content, carbon monoxide content, gaseous acidic and alkaline content, ozone and other gaseous oxides, odors, etc. The oxygen content is not less than 99.5%. At the same time, carbon monoxide, carbon dioxide and other harmful gases and impurities must be treated during the production process. filter. Using industrial oxygen instead of medical oxygen is harmful to the human body. After searching the relevant research literature, there is no summary of clinical cases and no experimental animal research. It’s just that all people say in general that during the industrial oxygen compression filling process, acidic or alkaline lubricating water, which is mixed with other impurities, is often mixed in and remains in the cylinder. The loss of time may cause the inner wall of the cylinder to rust. Generate extra gas impurities. The piston sealing material in the oxygen compressor may also produce some harmful gas impurities and powder mechanical impurities during the operation of the machine. In this way, there will be impurities that are extremely harmful to the human body in the industrial oxygen. Once the human body inhales an excessive amount, it will cause or aggravate the respiratory system disease, and in severe cases, it will cause the death of the patient. However, these harmful consequences are not based on industrial oxygen research, but are based on other research results. However, it does not deny the potential possibility of these hazards, but lacks scientific and quantitative experimental or clinical data to support it. These views. According to the national standard of “Medical Oxygen” and the “Chinese Pharmacopoeia”, the oxygen content of medical oxygen cannot be lower than 99.5%, which does not mean that oxygen with an oxygen content of lower than 99.5% cannot be used for prevention and treatment. Before 1988, industrial oxygen was a legal medical oxygen product. It can be described as blooming all over the country. It can be found in every hospital, and it has indeed saved many lives. But it cannot be legal now because it was once legal. Especially with the development of science and technology, it has the ability to replace industrial oxygen with medical oxygen with less potential harm. We cannot let industrial oxygen hold the benchmark of the past and measure current health. Clinical experiments have proved that the oxygen content of human breathing and physiology for medical oxygen can meet prevention and treatment as long as it is greater than 90%, but why does our national standard strictly require oxygen content ≥99.5%? The reason is that the national standards for the oxygen content of medical oxygen are all determined based on the oxygen obtained by the cryogenic method of separating air. Medical oxygen produced by cryogenic separation of air contains, in addition to oxygen, moisture, carbon dioxide, carbon monoxide, gaseous acids and alkalis, ozone and other gaseous oxides, which are harmful to the human body. If the oxygen content is less than 99.5%, the content of these harmful ingredients will increase, which will cause harm to human health. Therefore, for medical oxygen made by cryogenic separation of air, the oxygen content shall not be less than 99.5%. The formulation of the standard is only to have as few harmful ingredients as possible, but it cannot absolutely eliminate harmful ingredients. From this, it is clear that the key to determining whether oxygen can be used in medical care is that the content of harmful components in the oxygen cannot exceed the standard value of the national pharmacopoeia. Industrial oxygen can also be used in medical treatment if it is produced using “Good Manufacturing Practice for Pharmaceuticals” (GMP). But this violates the law, the two must be produced separately. The status quo in our country is that many companies give consideration to both production at the same time, which is also caused by inadequate supervision. In fact, when medical institutions use oxygen for treatment of patients, the terminal oxygen content is more than 99.5% of medical oxygen. Generally, according to the needs of the patient’s condition, a certain amount of air is diluted in pure oxygen to reduce the oxygen content, so as to avoid oxygen poisoning. Scientific experiments have proved that if a person is in a pure oxygen environment of half an atmosphere, oxygen has a toxic effect on all cells of the human body, which can cause pulmonary edema, pulmonary congestion and hemorrhage, seriously affect respiratory function, and damage all organs of the human body. . Exceeding the limit of oxygen required by the human body, oxygen can also endanger life, ranging from disability to death. It can be seen from this that if medical oxygen is used incorrectly, it can also lead to serious consequences. Most of the domestic oxygen production process, the oxygen produced is extremely pure, but in the process of packaging, due to different requirements for moisture, impurities, and other gas content, the so-called “medical oxygen” and “Industrial Oxygen”. To meet the quality requirements of the Pharmacopoeia, a special oxygen-filling device is used to separate oxygen, which is “medical oxygen”, otherwise it is “industrial oxygen”. In other words, there is no difference in production between medical oxygen and industrial oxygen, but the final “finished product” is different due to different requirements and different equipment in the sub-packaging. In addition, the canned “medical oxygen” cylinders are inspected every three years, with cleaning, heating, drying, and evacuating processes; operators must undergo annual physical examinations to rule out infectious diseases. Industrial oxygen does not have this requirement. If there are no strict requirements for medical oxygen production, filling, and cylinder handling, it will become industrial oxygen. It seems that the boundary between the two is the difference between the inspection indicators and the production standards, which caused the two to diverge, and the results will be completely different. my country has a vast territory and very unbalanced development. Many backward areas are not faced with the problem of medical oxygen or industrial oxygen, but the problem of no oxygen available. The price of medical oxygen is 3-4 times or even higher than that of industrial oxygen. The industrial oxygen production standard is low, the cost is not high, there are not so many clauses and clauses, the use is very popular, and it is easy to get. In the absence of medical oxygen, if industrial oxygen is not allowed to treat patients, how should the responsibility of the hospital to save the dead and heal the wounded be implemented? However, the national conditions have changed. We have the ability to make high-standard and strict medical oxygen replace the low-standard and loose-required industrial oxygen. Putting people first, respecting life equally, and minimizing harm is the first priority. In other words, it’s okay to directly pull the industrial oxygen from Tata Group for use. After all, life is a matter of life, so how many impurity gases does it have?

Let alone, the manufacturing technology of cryogenic liquid oxygen storage tanks is still a bit difficult. Those are all low-temperature special stainless steels. China couldn’t make it on its own 20 years ago. This kind of material is imported.
There is also a liquid oxygen cryogenic valve, which is a hollow ball valve. This kind of thing is the recent great development of aerospace. The low-temperature engine is successfully equipped, and the technical public relations are taken down after constant trial and error. The low-temperature valve was also imported before.

Not difficult and difficult.
It’s not difficult.
It is not difficult to create difficulties, but also difficult.
Can it mean that there are still companies created throughout India.
Not difficult and difficult means that it is far from enough.
Difficult and not difficult means that there is an overcapacity nearby that wants to reduce production capacity and transfer backward industries.
It’s not difficult to create difficulties, but also difficult means that even if I die, I definitely don’t need someone next to me when I die.
Really fragrant?
I have a backbone in Yin Jingze!

There is a misunderstanding: The oxygen in the hospital is bought from the air separation plant in high-pressure oxygen cylinders. In fact, hospitals in developed areas buy liquid oxygen, then build an oxygen supply station in the hospital, and finally centrally supply oxygen through the hospital’s oxygen pipeline. The latter is not only more efficient than the former for oxygen transport, but also cheaper. The cost of providing the same volume of oxygen in American hospitals, which are all expensive, is only 10% of that of hospitals in underdeveloped areas in Africa. It is a pity that hospitals in India, like African countries, are underdeveloped hospitals and do not have the ability to centrally supply liquid oxygen storage, so they can only rely on the purchase of oxygen cylinders. But if you do this, the most powerful country will still be hypoxic when it should be hypoxic. Simply wanting to build a few more gas cylinders and a few large gas cylinders is a completely useless struggle, and basically has nothing to do with whether India has the ability to manufacture more gas cylinders. The construction of a modern hospital cannot be completed overnight. So now the oxygen problem in India is basically a dead end. The above are not my YY, but some internationally renowned media interviewed experts in the field and spoke from the experts. Zhihu gave a random answer to this question, it may be that everyone does not read the international news.

It is not difficult to make an oxygen tank under normal pressure. The technical difficulty is not higher than that of making a squirrel mandarin fish, but does it make sense to make such an oxygen tank? Oxygen will not run into the gas tank by itself, but oxygen is to be produced. Generally, oxygen production is divided into electrolysis and compression separation. The cost of electrolysis is too high and it is not suitable for obtaining large amounts of oxygen. The economical method is compression separation. Compression and separation simply means multi-stage compression, which uses different condensation temperatures of gases to obtain nitrogen, oxygen and other gases from the air. This thing is not a strategic material, and a treasure with money will be delivered home by mail. However, storage and transportation in liquid oxygen is a relatively high-tech thing. Oxygen is harmless to humans and animals at low concentration and normal pressure, and everyone loves it. However, once the concentration rises or the phase state changes, it becomes extremely dangerous. This thing requires only a small amount of combustible elements and an increase in temperature will cause combustion or even explosion. This is needed for oxygen storage and phase transformation: oxygen station. Doing this stuff is a technical job, and there are no more than 50 companies in my country that have the ability and qualifications to do stuff (maybe more than that). Do you think a country like India is capable?

It just so happens that my work has encountered similar problems. For domestic production of lasers, some equipment needs to be purchased from France. We can’t make the required laser because of the lack of laser technology? In fact, the domestic laser technology is already very strong, but the lasers produced are not as good as foreign ones. Although we have advanced laser technology, the supporting power supply, water chiller, control platform and other technologies are not good. These devices are not core but necessary. In the end, it is still unable to fully localize the production of advanced lasers. Corresponding question: “Is it difficult to make chips in China?” The difficulty is not the technology of making chips, but the entire upstream and downstream industrial chain. If one section fails, high-end chips cannot be made. Back to the question itself: “Is it difficult for India to manufacture large oxygen tanks?” Perhaps the technology for manufacturing large oxygen tanks alone may not be bad. However, the entire industrial chain required, including steel manufacturing, manpower, and the government’s ability to mobilize in emergency situations, does not work, and large-scale oxygen tanks are difficult to mass produce.

Would love your thoughts, please comment.x
