Go back to the past and be a schoolboy

Chapter 201 Every step we take is to fill the gap in the country
In order to overcome various problems in the experiment process, Cheng Nuo specially formed a research team to concentrate on solving various obstacles in the way.

In the beginning, the method of iron oxide was used to filter out most of the carbon monoxide in the produced gas, as Cheng Nuo expected, but the problem is that this method cannot completely remove all the carbon monoxide. , the hydrogen still contains a small amount of carbon monoxide.

Faced with this question, everyone in the chemical engineering team fell into deep thought.

The entire conference room fell into a strange silence, only the hands of the clock on the wall were rattling.

Liang Qichao was originally an outsider. He was okay at first, and he could be an atmosphere group or a logistics group. Now he encountered academic problems that he didn't understand, and the room was too quiet, so he couldn't sit still.

Coughing on purpose, Liang Qichao broke the silence: "Well, Zhiyuan, I don't think everyone can think of a reason right now, I think it's better for us to discuss something else, change our minds, and give me some ideas. "

"Oh? Please tell me, Mr. Ren." Cheng Nuowen said.

"Actually, it's easy to say, Zhiyuan, didn't you ask me to contact Liu Xiang a lot? I did as you said in the beginning. Contacting each other is considered harmonious, otherwise we wouldn't let us come under their jurisdiction. But the current situation is somewhat unpredictable for me." Liang Qichao said slowly.

"Is it because of the scuffle in Sichuan? It is estimated that it will not be calmed down in a short time, but the scale will not be too large, and it will not affect us in a short time. If you are worried, you can also bet on that man named Liu Wenhui. Xiang is also from the same family, and is also related to uncle and nephew." Cheng Nuo hesitated for a moment, and said slowly.

Speaking of which, Cheng Nuo had a habit of being too devoted to things, whether he said it was good or bad.

The good thing is that when he conducts scientific research, he can devote himself wholeheartedly to it, forget everything, and use his time efficiently, which has the effect of getting twice the result with half the effort.

The bad thing is that when he is busy with one thing, he will instantly forget all the things around him and the outside world, it is easy to miss some things, and he is relatively slow in strategic response.

"Yes, from the perspective of others, this Liu Xiang is indeed a talent, but the problem is that this person is too repetitive. I am afraid that if we invest too much in him, he will backtrack in the future, and the gain will not be worth the loss. What I hate most in my life is this Such a politician." Liang Qichao's tone was a little hasty.

Cheng Nuo shook his head with a smile, and said meaningfully, "Isn't it a must-have skill for politicians to keep promises?"

"This..." Liang Qichao was at a loss for words for a while, he didn't want to admit it, but thinking of all the past on the mountain, he had to nod: "That's true."

In fact, it's no wonder Liang Qichao looks like this, it's just that the "war to protect the country" in Sichuan is too funny.

When the Yasukuni Campaign began, Liu Xiang was a brigade commander in the First Division of the old Sichuan Army.

The First Division stood on Liu Cunhou's side and blocked the Yasukuni Army's westward advance.

In Neijiang's monastic field, Yisidui, Pimu Town, Dongjiezi, Baima Temple and other places in Neijiang, Sichuan, the troops led by Liu Xiang fought fierce battles with the Yunnan-Guizhou Army.

When Liu Cunhou's army was defeated and retreated, and Xiong Kewu, a member of the Kuomintang, pursued the victory, the first and second divisions of the old Sichuan Army immediately fell to Xiong Kewu's side, and immediately sent a power-up in response to the Dharma protector.

A vigorous Yasukuni battle ended in such an almost absurd way.

No wonder Liang Qichao despised Liu Xiang for his sloppy behavior.

But it was such behavior, because Xu Xiaogang, the former commander of the first division, felt ashamed to face Xiong Xiaowu, so he sent a telegram to resign after the war. Instead, Liu Xiang took this opportunity to climb up directly and was directly promoted from brigade commander to division commander .

Although the entire Sichuan Army was later reorganized into seven divisions, only Liu Xiang's division has a long history, is well-trained, and is relatively complete.

Moreover, Liu Xiang was more of a professional soldier at this time, and he didn't have the intrigue of later politicians, so he was relatively "simple".

But right now, the "war to protect the country" is not over yet, which means that this is the perfect opportunity for Cheng Nuo and the others to place their bets.

Under Liang Qichao's eager gaze, Cheng Nuo said with a hammer: "We not only want to place a bet, but also need to add more chips. How about this? You can contact Liu Xiang later and say that we are willing to integrate the chemical plant locally and build a complete chemical plant." The supporting industrial park forms a small internal circulation industrial system.

One day, with the expansion of our industrial scale, this internal circulation will surely expand to the entire Sichuan, Southwest, and even radiate the entire land of China. There is great potential.

During this period, we will generate high tax revenue to feed back the local area and support local development. Whether it is building schools or hospitals, we can do our part. "

After a short pause, Cheng Nuo continued: "In my opinion, what we use most from Liu Xiang is his ambition, his heart to climb up and expand outward. After all, although our Academy of Sciences has come to Sichuan, our vision is not good enough. It will only focus on the local area.”

After finishing his speech, Liang Qichao took it very seriously. After asking a few more questions and getting the answer he wanted, he turned and left, embarking on the road to contact Liu Xiang again.

After Cheng Nuo's matter was resolved, the members of the research team over there approached him again.

Fan Xudong smiled: "Zhiyuan, I know how to solve the problem of residual carbon monoxide."

Cheng Nuo couldn't help laughing: "Tell me, what did you discuss?"

Fan Xudong pulled the mobile blackboard over, quickly wiped the things on it, and introduced while doing calculations: "We all know that carbon monoxide is poisonous and harmful. It not only affects the purity of our synthetic ammonia, but also harms the physical and mental health of workers and masters, so after we discussed it, ,

It is believed that the remaining small amount of carbon monoxide is further removed with copper ion solution... ",

"Wait." Before Fan Xudong finished speaking, Cheng Nuo interrupted him directly: "Although the idea is good, but don't forget that most of the devices we use are made of iron parts. Iron has a corrosive effect, we can't produce a batch of chemical fertilizers, just replace a batch of equipment.

Not only is it more troublesome to install, but our production costs will also remain high. When it comes to retailing foreign goods, our prices are almost uncompetitive at all. If there is a slight trend of price wars, we will face bankruptcy! "

Fan Xudong thought about it carefully, and it was really the case, and his face was a little ashamed: "Oh, it's all because I didn't think deeply enough, just after discussing the answer, I couldn't wait to find you, I didn't expect to forget about it .”

Cheng Nuo waved his hand generously: "I don't think it's a big deal. Anyway, you all came to a conclusion after discussing it. Let me think about it... Although the copper ion solution is corrosive to a certain extent, it is not completely insurmountable."

Frowning and thinking for a moment, Cheng Nuo made up his mind and said, "Well, we have no other way out right now. Let's start with the copper ion solution and see how to solve the corrosion problem."

Fan Xudong nodded: "Alright, then do as you said, and I will arrange the team members to tackle technical problems."

After saying this, Fan Xudong was about to leave, but before he could turn around, he was stopped by Cheng Nuo.

"Collective action is too slow, how about this, you divide the team members into parts, each group is responsible for a direction, and regularly organizes and reports the results. After a group has made progress, other groups immediately follow up to maximize our progress. efficiency."

Fan Xudong smiled and said, "This is even better. I believe we will be able to solve this problem within half a month."

Sure enough, as expected, even a little bit beyond expectations.

In less than a week, the instrument corrosion problem was resolved.

It only needs to add a certain amount of ammonia to the copper ion solution used to remove carbon monoxide to solve the corrosion problem of iron.

So far, the process of producing high-purity hydrogen in large quantities has finally been developed.

In this way, new problems are constantly emerging and being solved.

After the development of cheap and high-efficiency catalysts and the mass production of high-purity raw gas have been solved one after another, how to design and manufacture a large-scale synthesis reaction device that can withstand high temperature and high pressure has become a top priority for Cheng Nuo.

Although the experimental device previously developed by Cheng Nuo can provide a lot of reference for the development of the pilot test reaction device, it is obviously not feasible for the pilot test reaction device to simply scale up the laboratory device.

When developing the pilot test reaction device, the first problem encountered was the problem solved by the large air compressor.

Although there are some large-scale factories in Chongqing, the largest air compressor at that time was used to deliver air to the mine.The maximum pressure of this compressor cannot meet the requirements of the ammonia synthesis reaction unit at all.

As for the compressor used for liquefied air, although it can be enlarged, it cannot continue to operate under high temperature conditions, because its joints are made of copper, and the melting point of copper is too low, only 1083.4 degrees Celsius.

And the airtightness of the compressor for refrigeration is not strong, which is prone to leakage.

Therefore, Cheng Nuo had no choice but to call Tesla, who was researching radio, to redesign the air compressor according to the needs of synthetic ammonia production.

And the drama of restarting the design is not over yet, because the working environment of the ammonia reaction vessel is very harsh.

Its internal pressure is usually 20 times that of a steam boiler, and the temperature is so high that it can burn iron red. In this case, it is also necessary to ensure that the nitrogen and hydrogen continuously input at a certain ratio do not leak, and the generated ammonia can be easily pumped out. Splitter.

Therefore, Cheng Nuo had to design and manufacture a batch of special monitoring instruments by himself.

In fact, Cheng Nuo also felt a little tired when he got here in the middle, although he knew that the chemical industry was poor and empty, and everything needed to be started from scratch.

But he never expected that there is not even a "knife" that opens the way in China.

After careful calculation, the first scientific instrument company in China could not be established in Shanghai until 1925. Before that, all instruments used for teaching or scientific research had to be purchased from foreign countries.

This is also the reason why the ammeter was created by Huasheng Electric Manufacturing Factory, which caused a sensation in the society.

Without him, only Watson could manufacture domestic products at that time.

Looking at the stall that is getting bigger and bigger, Jiang Jiangzuo, a layman, can't help but feel a little depressed: "Zhiyuan, I remember that although our chemical problems keep appearing, they are constantly being solved. Why are the problems solved more and more? Are there more and more?"

Cheng Nuo smiled bitterly and said, "Because every step we take is a field that the Chinese people have never set foot on, and a scenery that has never been seen before."

Jiang Jiangzuo felt a little better: "That's right, with people like us leading the way, it will be relatively easier for the latecomers to move forward, but it's just a pain for us."

Cheng Nuo nodded: "That's right, in order to install these instruments and meters, a batch of special joints and valves have to be developed. Besides, how to heat the synthesis reaction vessel? How to maintain the pressure inside the synthesis reaction vessel? What materials are used? Production? These problems need to be solved one by one.

However, we are not researching these things for nothing. We have been writing a research log in the middle, and we can sort out the correct research results and use them for other purposes in the future.Wrong ones also have their merits, and they are collected for your reference so as not to fall into the same pit twice. "

Those who have the will, things will be accomplished, the boat will be broken, and the hundred and two Qinguan will eventually belong to Chu.

Those who work hard, live up to the sky, and try their hard work, three thousand Yuejia can swallow Wu.

In the later research, especially in the process of developing the synthesis reaction vessel, Cheng Nuo and his colleagues not only studied the most advanced steam locomotives, gasoline engines and diesel engines at that time, but also visited local steel factories.

Picking the best, I found a factory with decent steelmaking technology. After spending a month, I finally designed and manufactured two cylindrical synthetic reaction vessels with a height of 2 meters 4, and placed them in a reinforced concrete container. In the completed protective cover.

Of course, high-quality concrete still has to buy foreign goods.

It's a pity that the synthesis reaction vessel exploded after only three days of operation. Cheng Nuo couldn't figure it out. He thought it was due to poor steelmaking technology, and the brittle inner wall of the reaction vessel made of carbon steel caused the explosion.

After several demonstrations, it was discovered that hydrogen atoms with very small particle sizes penetrated into the carbon steel after thermal expansion under high pressure and reacted with the carbon element in it.

No matter how good the steel is, it cannot stop the reaction of hydrogen atoms.

In the middle, Cheng Nuo also wanted to put on a protective layer to prevent the two sides from reacting.

It can be argued that, with the technology at that time, high-strength steels contained more or less carbon elements. No matter what protective layer was applied to the inner wall, hydrogen atoms could easily penetrate it under the action of high pressure, and Drilling into the interior of carbon steel, unless the inner walls are coated with a layer of pure gold, is too expensive.

After several twists and turns, three or four months passed like this.

Cheng Nuo knew that he couldn't go on like this anymore. He broke the can and smashed it, so he simply drilled some small holes in the carbon steel cylinder to directly discharge the small amount of hydrogen that had penetrated to the outside of the inner lining.

Unexpectedly, it worked wonders.
