Harpy these days, many inquiries, in the whole of Germany, the strongest place in high-pressure closed containers and chemical synthesis, in the Berlin University of Technology, the Department of Chemical Engineering, is also the most powerful place in the whole German chemical industry, many shocked the world chemical achievements, such as urea, such as vulcanized rubber, for example, some petrochemical achievements, and here has a direct connection, the current annual chemical science awards and Germany, Europe, and even the United States Some chemistry awards, here are won from time to time.

If Yang Yuanzhao is here, he will definitely tell Harpy again, the inventor who invented synthetic ammonia, the famous Haber method of synthetic ammonia, Fritz Haber, was at the Technical University of Berlin, discovered and perfected the technology of synthetic ammonia, and created a new synthesis of ammonia from the air.

As the top university in Germany, the overall strength of science and engineering ranks among the top three in Germany, and the chemical engineering discipline is even more outstanding.

Harpy searched for the building of the Department of Chemical Engineering, and found the deputy director of the Department of Chemical Engineering, Professor Hove, who was Jewish, and before coming to the Technical University of Berlin, he contacted the Guò Jewish Federation, and Hove was waiting in the office, and they agreed on the time at 3 o'clock.

At the appointed time, he saw Professor Hough, like an old friend, and after chatting a few words, Harpy told the purpose of his coming straight to the point, and the high-pressure closed container was also one of the equipment that Yang Yuanzhao specially added to the list before he set off.

At first, he didn't care, but after asking, Harpy learned that high-pressure closed containers are definitely not an ordinary thing, this is a new subject.

It must withstand huge pressure, Yang Yuanzhao's number jù is under 70 atmospheres, can work smoothly, this is okay, some high-density sealed cylinders, can achieve such an effect, but the latter condition, but the ordinary closed container, can not be used, this container, need to withstand the temperature of more than 600 degrees.

High temperature, the impact on metal materials, far above high pressure, high pressure and high temperature, the performance of the metal, will change greatly, in the case of low temperature and low pressure, the performance of the metal is stable, can be obtained by the method of measurement, at higher temperatures, many of the usual excellent metals, will appear different degrees of attenuation, or even aging, in this case, to obtain reliable metal, it is very critical, this is also the only way to solve this container.

Hough listened to Harpy's request, and couldn't help frowning, the high-pressure closed container, and also need to work at a temperature of about 600 degrees, this is a field that the School of Chemical Engineering has never been exposed to, and was about to open his mouth to refuse, suddenly, Hough seemed to remember that there was a young lecturer in the Department of Chemical Engineering, who seemed to be doing research in this area, and seemed to have achieved results.

"Harpy, I don't know much about this field, but I'll bring in an expert for you, and if he can't solve this problem, then there's really no way!"

Harpy said, "Then there's Professor Rauhoff!" ”

Using the pager, he called a teacher, and after a brief explanation, the teacher went out, and soon returned, and with him came a middle-aged man with slightly bald hair and obvious Jewish characteristics.

"Mr. Hough, you're looking for me!"

"It's not me looking for you, it's this gentleman looking for you, he's a big businessman, and he wants you to help complete a project!"

Hough's introduction made the middle-aged man's eyes light up, and he greeted him enthusiastically and said: "Hello sir, I'm Fritz Haber!" ”

In the past period, Harpy has seen many high-level people, even well-known scholars, he will not know that this is one of the most famous chemists in Germany in the future, and he is also a person with mixed reputation, because he won the Nobel Prize in Chemistry in 1918 for synthetic ammonia, and because of the relationship between the chemical arsenal during World War I, he produced a large amount of chlorine, mustard gas and other poisonous gases, and millions of people died because of him, so he was criticized by the academic community.

Now Haber, just an ordinary chemist, his idol, is the invention of urea, known as the agro-chemical industrialist Liebig, he is currently carrying out the real yàn, is the purpose of Yang Yuanzhao's high-pressure closed container, the synthesis of ammonia in the air, opening a new era of chemical industry, but also let Germany, which suffered from the embargo, have the confidence to wage war in World War II, because synthetic ammonia is the only raw material for making nitric acid in addition to natural saltpeter.

Haber's enthusiasm made Harpy a little overwhelmed, and Hove next to him introduced: "Haber is our college, and the experts who are most familiar with high temperature and airtight are easy, you have a good chat!" ”

After Hough finished speaking, he went out, leaving the office for Haber, who also understood in Hough's brief introduction that the other party's purpose was to seal the container with high pressure.

High-pressure closed container is a new topic, knowing that someone also needs high-pressure closed container, it is also very strange, the same met synthetic ammonia enthusiasts or researchers, towards the identity of the big boss, of course Haber is willing to say a few more words, you know, he has recently carried out the real yàn, to the key step, the funds can not keep up, he can carry out this step, thanks to the sponsorship of the two enterprises, his progress can not make these two enterprises satisfied, the funds began to drag, the person in charge began to become elusive, It gave him a lot of headaches.

"I don't know what kind of specs you want!"

Harpy honestly said it according to Yang Yuanzhao's standards, and said: "70 atmospheres, 600 degrees of high temperature, the volume should be large!" ”

Haber frowned and said, "With such a high demand, what do you want to do, industrial production, scientific practice?"

Harpy knows so much, Haber asks again, but he doesn't know, Haber also thinks that high-pressure closed containers, perhaps, really meet peers, research in a field, is like moving forward on a dark road, there is a communicator, it is better than constantly hitting a wall.

After seeing Harpy, it's not like this at all, I don't know much about synthetic ammonia, just according to the design standards to make zuò, 70 atmospheres, 600 degrees of temperature, at most just said, as much as possible to make it bigger, this condition is much higher than synthetic ammonia, at this time, Haber discovered the method of making synthetic ammonia, but he has not even completed the industrial production, just the study of the real yàn room, under the pressure of 20 atmospheres and a temperature of about 500 degrees, to complete the process, Even if it is a catalyst, it is far from mature, and it is still nervously trying to solve the problem and put this technology into real industrial production.

Haber is really a professional, for the comparison of high-temperature and high-pressure vessels, soon, according to Harpy's requirements, calculated some numbers jù, and then through guò comparison and scrutiny, slightly solemnly said: "The maximum can only be 90 cubic meters, after accurate design, even less!" ”

90 cubic meters, Harpy frowned, and asked with a little inquiry: "Will it be too small!" ”

"It's not small, 90 cubic meters, you can synthesize at least 100 tons of liquid raw materials at one time!" Haber said weakly, he is very sure, Harpy is a chemical novice, for chemical synthesis is only a half-understood, but people are really rich, considering not at all the economic issues, considering the problem of performance indicators, high-pressure closed containers, the larger, the greater the pressure on the walls of the container, which is common sense that everyone knows in the metallurgical and chemical circles, 90 cubic meters is less than twice as high as 50 cubic meters, but the price, at least quadruple, his real yàn into the bottleneck, The key is that the money is troublesome, there is not enough real yàn, there is no better high-pressure closed container, he has succeeded in synthesizing ammonia, but he is still stuck.

Harpy looked at Haber, he had an advantage, that is, he could listen to the professional's story, and after repeated inquiries, he knew that he could not improve, so he agreed, as much as possible to ensure that it was more than 90 cubic meters, and the minimum could not be lower than 80 cubic meters, for which he could directly prepay all the money.

Haber's eyes lit up, this is a high-pressure closed container, and it is a move to create zào, so he shouted the price relatively high, 50 cubic containers, but 80,000 marks, more than 80 cubic meters, he shouted a high price of 500,000, in his opinion, at least to be greatly discounted, 350,000 is his psychological price, but unexpectedly, Harpy waved his hand, so decided, ordered 3 at a time, and directly to the Department of Chemical Engineering of the Berlin Polytechnic University, leaving 1.5 million marks.

Haber hurriedly agreed, but told Sù Harpy that this kind of high-pressure closed container is extremely difficult to produce, and it will take 3 months.

"It's going to take 3 months!" Harpy frowned and asked, "Can it be faster!" ”

"No, this needs to be customized, in order to increase the strength, even the material needs to be passed on the 10,000-ton hydraulic press, which is a national heavy weapon, even if there is a brand of the Berlin Institute of Technology, it will take a month at most, to a month and a half!"

Hearing the 10,000-ton hydraulic press, Harpy stopped talking, this is a real national heavy weapon, even in Germany, there are only the main shaft of the battleship, the propeller, the important parts of the engine, as well as heavy artillery, naval guns and the like, you can pass it on the 10,000-ton hydraulic press, and take this high-pressure sealed container to the 10,000-ton hydraulic press for a while, I'm afraid it's still for the sake of money.

Seeing that Harpy stopped talking, Haber hurriedly made a series of assurances, such as carefully making the high-pressure closed container, adding some parts that didn't look big, but were very useful, these parts were some of his achievements when he was in practice, and they all played a considerable role in the sealing of the closed container.

In short, after all his efforts, Harpy finally left satisfied, of course, before leaving, he put down a check for 1.5 million marks and left it directly to the School of Chemical Engineering as funds for the production of 3 closed containers. RS
