“What do you want to know?”Wu Shican asked.

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

Hearing this question, Wu Shican's face of the expression became serious, he broke his finger to calculate for a while, said: "It is a lot of difficulties, but if we are determined to do, regardless of cost, or there are enough people's financial resources to invest, a lot of difficulties are not impossible to break through."Generally speaking, large fertilizer equipment, like other chemical equipment, involves three aspects.

“Design, manufacture, install, right?”Feng Xiaochen told him.Feng Xiaochen had already asked 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, "Yes, it is true that these three aspects are indeed."Let's analyze: in terms of design, we are mainly subject to synthetic ammonia process patents.Several synthetic processes currently used internationally, including the Texa craft, the Schell process, the Kellogg process, etc., have already registered patents, and if we want to use them, we need to pay patent royalties to these patent holders.When I was in the Chemical Design Institute, several experts also engaged in the development of the synthetic ammonia process, and there was some progress.However, the State is not investing enough in this area, and in addition to theoretical research, process development also needs experimental support, because the lack of funding, their research is difficult to continue.”

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

Wu Shican nodded definitely and said, “This is no problem, we have not eaten pork, can we still see pigs running?”More than a dozen sets of large-scale fertilizer equipment have been introduced in China, and even if it is based on cucurbit painting, we can also make the design.”

"That's the first thing you said."Feng Xiaochen said, “What about the second aspect?”

“The second aspect is the creation, which should be a better area for you to understand?”He said with a laugh.He knew that Feng Zhichen had some knowledge of mechanical manufacturing, and his practical experience was even richer than Wu Shican himself.

Feng Xiaochen said: "The manufacture of chemical equipment has its own laws, I now understand the situation, domestic enterprises for other parts of the large fertilizer device has some confidence, especially if you can introduce Japanese technology, the difficulty of completing the manufacture of these devices is not particularly large."The main obstacle is in the five major compressor units, Xinyang dihua machine director Deng clearly told me that they do not dare to undertake the task of the compressor unit manufacturing.

Wu Shican said, “That’s true.Other parts are mainly some towers, tanks, pipes and so on, our domestic technology level and foreign countries have some gaps, but it is not impossible to make up.But the compressor unit involves a lot of technical problems, and our country has been very weak in this regard.Not only the compressor unit on the fertilizer device, but also the three compressor units used on the large ethylene are also three roadblocks, and the 110,000 tons of ethylene research organized by the National Planning Commission a few years ago is finally stuck on this.

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

The large ethylene plant is also one of the 11 major equipment responsible for the reinstallation office.In the mid-1970s, the National Planning Commission organized some scientific research institutions and chemical equipment enterprises to carry out joint research, trying to solve the problem of localization of 110,000 tons of ethylene equipment per year, and finally failed to do so.Wu Shican said that the three compressor units, namely ethylene compressor, propylene compressor and cleavage compressor, its manufacturing is extremely difficult, China has been only dependent on imports.

“The difficulty of manufacturing these compressors is mainly in the material.”Wu Shican explained, "These kinds of compressors are working in the low temperature conditions of minus tens of degrees or even on Baidu, ordinary metal materials in this extreme low temperature will become very brittle, can not withstand mechanical impact and compressed gas pressure."The study of low temperature resistant materials is our short board, even if the use of imported materials, the processing technology must also be explored from scratch, which is very difficult.Moreover, if the low temperature material is completely dependent on imports, we will also fall into a situation of being subject to people.If people want to get our necks, they can sell materials more expensive than equipment, and we can't do anything about it."

"This time in Japan and the Chemical Equipment Association in the talks, they agreed to transfer most of the technology, but for the smelting technology of low-temperature steel is not at all relaxed."They claim that the steel was sourced directly from Japanese steel mills and that they do not have the technology to do so.”Feng Xiaochen said.

Wu Shican sneered, “If we believe this, it is a fool.”Low temperature steel is the lifeblood of chemical equipment manufacturers, how can they not master this technology?Steel companies will not take the initiative to study these steels, they are in cooperation with chemical equipment companies to carry out this research, the results are naturally shared by the two.The Japanese just don't want to transfer these technologies."

"I understand."Feng Xiaochen said, "On this point, we have argued for it, and even to give up the purchase of all large fertilizer equipment, but the Japanese insist that we can not transfer, we can't do it."After all, they make a lot of concessions, and our demands will not work together if they exceed their bottom line.”

"That's the second problem I'm talking about."Wu Shican said.

“Then the third aspect is the installation.”Feng Xiaochen asked again.

Wu Shican said: “The situation in this area is a little better.We have also trained a lot of chemical equipment installation team over the years, and they lack only the installation experience of large-scale chemical equipment.Foreign chemical equipment arrangements have many special equipment and tools, we are also lacking in this regard.However, if we can introduce some equipment and then let these installation teams get exercise in the construction of the newly introduced five large fertilizer equipment, it is entirely possible to form our own large-scale fertilizer installation force.”

"I understand."Feng Xiaochen, he thought for a moment, said: "Old Wu, just now I was there in Luo to report to him on the matter of large fertilizer equipment, talk about an idea, I want to listen to your opinion, see if this idea is feasible."

Wu Shican laughed, “I’m afraid this idea was proposed by your little Feng, right?”You can always have some unexpected ideas, and I'm really interested in learning."

Feng Xiaochen smiled and waved his hand to show modesty, and then said: "I suggested to Director Luo that for large fertilizer equipment, we can take the method of conference warfare and concentrate the strength of the whole country to overcome all difficulties."Do you think this is feasible in your experience?”

“The national system?”Wu Shixuan paused for a moment and said, “If you can really take the national system, it is certainly feasible.”We have accumulated a lot of scientific research and manufacturing power over the years, if concentrated on large fertilizer equipment, should be able to break through the current obstacles.Just, just for the sake of a big fertilizer, are we worth putting in so much force?It's a little bit of a loss."

This kind of thing is very enjoyable to say, but when it is really done, it is still necessary to consider the cost performance.At that time, China engaged in two bombs and one star, relying on the national system, but that is because two bombs and one star are related to national security, and its importance can not be overestimated in any case.In order to bomb project, the state compressed a lot of infrastructure, put a lot of valuable steel, cement and talent into this bottomless pit, in exchange for a loud noise.

However, for the localization of large fertilizer equipment, the adoption of the national system method has made some small problems.After all, large fertilizer equipment can be bought from the international market, a set of equipment is tens of millions of dollars.If you pay hundreds of millions and billions of investment in order to achieve localization, it is not worth the loss.At this time, China is still very poor, limited funds should be used in more valuable aspects, in order to gamble a breath and invest too much in large fertilizer equipment, I am afraid the central government will not agree.

Wu Shican's doubts, Feng Xiaochen also thought, he even more than Wu Shican know how to weigh the relationship between pay and return.Hearing Wu Shican raise this question, he smiled and said, “Actually, it’s not so exaggerated?”According to your statement just now, the obstacles we can not overcome are mainly two, one is the synthetic ammonia process with its own intellectual property rights, and the other is the material of the compressor group.Other technologies we can solve by introducing, digesting, and absorbing methods.Can you estimate how much money is needed to develop your own synthetic ammonia process and develop the low-temperature materials needed for the compressor unit?”

"In terms of technology, 10 to 20 million, I think it should be enough."As for low-temperature materials, combined with our existing foundation, I am afraid we need to invest another 50 million to 100 million.”Wu Shican said, after that, he quickly added: "This is just a rough estimate of mine, scientific research this kind of thing, the uncertainty is very large."It’s possible that we don’t need to invest so much money, we’ve solved the problem.It's also possible that the money is put in, but the particles are not collected."

“I understand this.”Feng Xiaochen said, "So, old Wu, you think about how to do it, to see which units, which experts have the ability to solve these problems."As for the money, I'll find a way."

“Are you going to find a way?”Wu Shican glared at the boss, "Little Feng, this is not tens of thousands of dollars or hundreds of thousands of dollars, this is tens of millions or even hundreds of millions of dollars of funds, can you think of a way to come?" 」

“Let’s make people.”Feng Xiaochen said confidently.
