"What do you want to know?" Wu Shican asked. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

Feng Xiaochen said: "Lao Wu, you are an expert in chemical equipment, I want to ask you about the difficulties in our domestic fertilizer equipment." ”

Hearing this question, the expression on Wu Shican's face became serious, he crossed his fingers and pondered for a while, and said: "There are many difficulties, but if we are determined to do it, regardless of the cost, or if there is enough investment in people, financial and material resources, many difficulties are not impossible to break through." Generally speaking, large fertilizer equipment, like other chemical equipment, involves three aspects......"

"Design, manufacturing, installation, right?" Feng Xiaochen said for him. Feng Xiaochen had already consulted Deng Zongbai on this issue when he was in Japan, and Deng Zongbai listed these three aspects.

Wu Shican was not surprised that Feng Xiaochen was able to say these three points, he nodded and said, "That's right, it is indeed these three aspects. Let's analyze it: in terms of design, we are mainly subject to the process patent of synthetic ammonia. Several synthetic processes currently used internationally, including the Texaco process, the Scheer process, the Kellogg process, etc., have been registered for patents, and if we want to use them, we need to pay royalties to these patent holders. When I was in the Chemical Design Institute, several experts were also engaged in the development of ammonia synthesis process, and there was some progress. However, the state has not invested enough in this area, and in addition to theoretical research, process development also needs experimental support, because of the lack of funding, their research is difficult to continue. ”

"If we buy a process patent, can we design a full set of equipment with our own strength?" Feng Xiaochen asked.

Wu Shican nodded affirmatively and said: "This is no problem, we have never eaten pork, can we never see a pig run?" ”

"So that's the first aspect you said. Feng Xiaochen said, "What about the second aspect?"

"The second aspect is manufacturing, this should be the field you know better, right?" Wu Shican said with a smile. He knew that Feng Xiaochen had some understanding of machinery manufacturing, and his practical experience was even richer than Wu Shican's own.

Feng Xiaochen said: "The manufacturing of chemical equipment has its own rules, and what I have learned so far is that domestic enterprises still have some confidence in other parts of large fertilizer plants, especially if Japanese technology can be introduced, it is not particularly difficult to complete the manufacture of these devices." The main obstacle was in the five major compressor units, and the director of Xinyang No. 2 Chemical Machinery clearly told me that they did not dare to undertake the manufacturing task of compressor units. ”

Wu Shican said: "That's true. The other parts are mainly some towers, tanks, pipelines, etc., and there are some gaps between our domestic technology level and foreign countries, but it is not impossible to make up for it. However, there are many technical problems involved in compressor units, and our country has always been very weak in this regard. Not only the compressor units on the fertilizer plant, but also the three major compressor units used on the large ethylene are also three obstacles, and the 110,000 tons of ethylene research organized by the State Planning Commission a few years ago was finally stuck on this. ”

"I've heard about it. Feng Xiaochen said.

The large ethylene plant is also one of the 11 major equipment that the Heavy Equipment Office is responsible for. In the mid-70s, the State Development Planning Commission organized a number of scientific research institutions and chemical equipment enterprises to jointly tackle key problems in an attempt to solve the problem of localization of ethylene plants with an annual output of 110,000 tons, but ultimately failed to do so. The three major compressor units mentioned by Wu Shican, namely ethylene compressor, propylene compressor and pyrolysis gas compressor, are extremely difficult to manufacture, and China has always had to rely on imports.

"The difficulty in manufacturing these compressors is mainly due to the material. Wu Shican explained, "These compressors are working at low temperatures of tens of degrees below zero or even hundreds of degrees, and ordinary metal materials will become very brittle at this extreme low temperature, and cannot withstand mechanical impact and pressure of compressed gas." The research of low-temperature resistant materials is our shortcoming, even if imported materials are used, the processing technology must be explored from scratch, which is very difficult. What's more, if low-temperature materials are completely dependent on imports, we will also fall into a situation of being controlled by others. If people want to get stuck in our necks, they can sell the material more expensive than the equipment, and we can't do anything. ”

"When we negotiated with the Chemical Equipment Association in Japan, they agreed to transfer most of the technology, but they refused to let go of the smelting technology of low-temperature steel. They claim that the steel is sourced directly from steel mills in Japan and that they do not have the technology to do so. Feng Xiaochen said.

Wu Shican sneered: "If we believe this, we are fools. Low-temperature steel is the lifeblood of chemical equipment manufacturers, how can they not master this technology? Iron and steel enterprises will not take the initiative to study these steels, they are all cooperating with chemical equipment enterprises to carry out research in this area, and the results are naturally shared by the two companies. The Japanese just don't want to transfer these technologies. ”

"I understand. Feng Xiaochen said, "On this point, we have argued on the basis of reason, and even threatened to give up the purchase of all large fertilizer equipment, but the Japanese insisted that it could not be transferred, and we had no choice." After all, they still have a lot of concessions, and if our demands exceed their bottom line, we will not be able to cooperate. ”

"That's the second piece of the puzzle I'm talking about. Wu Shican said.

"So, what about the third aspect, which is the installation aspect. Feng Xiaochen asked again.

Wu Shican said: "The situation in this regard is slightly better. We have also cultivated a lot of chemical equipment installation teams over the years, and what they lack is only the installation experience of large-scale chemical equipment. There are many special equipment and tools for foreign chemical equipment arrangements, and we are relatively lacking in this regard. However, if we can introduce some equipment, and then let these installation teams be trained in the construction of the newly introduced five sets of large fertilizer equipment, it is entirely possible to form our own large fertilizer installation force. ”

"I see. Feng Xiaochen said, he thought for a while, and said: "Old Wu, just now I reported to Director Luo about the large fertilizer equipment to him, and talked about an idea, I want to hear your opinion and see if this idea is feasible." ”

Wu Shican said with a smile: "I'm afraid this idea was proposed by you Xiao Feng, right? You can always have some unexpected good ideas, I'm really interested in learning and learning." ”

Feng Xiaochen smiled and waved his hand to show his modesty, and then said: "I suggest to Director Luo that for the large fertilizer equipment, we can adopt the method of general battle and concentrate the strength of the whole country to overcome all the difficulties. In your experience, do you think it's feasible to do this?"

"Engage in a national system?" Wu Shican was stunned for a moment and said, "If the national system can really be adopted, then of course it is feasible." We have accumulated a lot of scientific research and manufacturing strength over the years, and if we concentrate on large fertilizer equipment, we should be able to break through the current obstacles. It's just, just for the sake of a big fertilizer, are we worth putting so much effort in......? It's a bit more than worth the loss. ”

The whole country system is very enjoyable to say, but in fact, when you really want to do it, you still have to consider the cost performance. In the past, China relied on the national system to carry out the two bombs and one satellite, but that was because the two bombs and one satellite were related to national security, and their importance should not be overestimated. For the atomic bomb project, the country compressed a lot of infrastructure and threw a large amount of valuable steel, cement and talent into this bottomless pit, which was exchanged for a loud bang.

However, for the localization of large-scale fertilizer equipment, the method of adopting a national system is a bit of a fuss. After all, large fertilizer equipment can be bought from the international market, and a set of equipment is tens of millions of dollars. If we spend hundreds of millions or billions of dollars of investment in order to achieve localization, it will be more than worth the loss. At this time, China was still very poor, and the limited funds should be used in more valuable aspects, and the central government would not agree to invest too much in large fertilizer equipment in order to gamble.

Wu Shican's doubt, Feng Xiaochen also thought about it, he even knows how to weigh the relationship between pay and benefit better than Wu Shican. Hearing Wu Shican raise this question, he smiled and said: "Actually, it's not so exaggerated, right? According to what you just said, there are two main obstacles that we can't overcome at present, one is the synthetic ammonia process with our own intellectual property rights, and the other is the material of the compressor unit. We can solve other aspects of technology by introducing, digesting, and absorbing them. Can you estimate how much money it would take to develop your own ammonia synthesis process and develop the low-temperature materials needed for compressor packages?"

"In terms of craftsmanship, 10 million to 20 million, I estimate that it should be enough. As for low-temperature materials, combined with our existing foundation, I am afraid that we will need to invest another 50 million to 100 million. Wu Shican said, after speaking, he quickly added: "This is just a rough estimate of mine, scientific research is such a thing, there is a lot of uncertainty." It's possible that we didn't need to invest so much money and we solved the problem. It is also possible to put money into it, but it will not be reaped. ”

"I understand that. Feng Xiaochen said, "That's it, Old Wu, you think about what to do, and see which units and which experts have the ability to solve these problems." As for the money, I'll figure it out. ”

"You're going to figure out a way?" Wu Shican glared at the boss, "Xiao Feng, this is not tens of thousands of yuan or hundreds of thousands of yuan, this is tens of millions or even hundreds of millions of dollars, can you come up with a way?"

"It's man-made. Feng Xiaochen said confidently.
