Of course, chemical fertilizers are not available, and there is a lot of chemical knowledge involved. Ivanov is currently the only one who can be a chemist www.biquge.info he has built a "laboratory" level "miniature chemical plant", so Yang Mingzhi still has a lot of information about the fertilizer plant plan.

Although there are many difficulties, he still believes that they can be overcome.

After resting, he and his wife went to the cafeteria to eat as usual, and Fuming also prepared a relatively hearty meal as usual, and the head of Catfish Village, Pobosky, and the professor of chemistry, Ivanov, also participated.

Naturally, some of the seized goods, such as French wine, were also present at dinner. Compared with ordinary soldiers who eat potatoes, officers can also eat bread and meat, and even drink alcohol, and their lives are indeed relatively luxurious.

Yang Mingzhi does not have such a high revolutionary consciousness, and he is not so persistent in enjoying some privileges. As a pragmatist, he confessed: "Thank you, comrades, for a hearty meal, and if our soldiers, our villagers, can eat enough butter and bread every day, this is my hope." ”

Hearing this, Fuming raised his glass. "These dreams will come true, and as long as we build a fertilizer plant, our food production will continue to rise!"

Yang Mingzhi glanced at Ivanov, who was holding a wine glass, his face was a little embarrassed, maybe drinking red wine was far less pleasant than holding tons of vodka.

"Alright! Cheers to our cause! Yang Mingzhi raised his glass.

He also had to keep his spirits in mind to discuss the matter with Ivanov about the fertilizer plant, and all the participants in the meal were just a few drinks.

After arranging everything that should be arranged, Yang Mingzhi followed Ivanov directly to his office.

Entering the house, under the dim oil lamp, Ivanov took off his hat and scarf and hung it directly on the wall, saying: "Deputy division commander, please sit at will." If you don't mind, we can talk about the fertilizer plant now. ”

"Okay, let's talk about it now."

Yang Mingzhi, who was wearing a military uniform, walked to Ivanov's desk and saw that there were still a few documents on the desk. Some of the yellowed paper is produced by the paper workshop in the blacksmith village, which solves the problem of office paper and ensures the needs of everyone when they go to the toilet.

The paper has been replaced by dense text, and there are some strange sketches. Raise it and knock it, it seems to be a picture of a factory apparatus, where large and small bottles are drawn, and there are official roads connected to them.

These properties make Yang Mingzhi think a lot - he is already sketching the image of the fertilizer plant of the future!

Yang Mingzhi turned around ecstatically and faced Ivanov.

"I really didn't expect that while I took the opportunity to take a bath, you were already designing our fertilizer plant? It seems that you are completely sure about this? ”

Ivanov shook his head. "Deputy Divisional Commander, please sit down, I must tell you the truth about this matter, I don't have such high confidence."

What's going on? Regarding a series of problems existing in the establishment of a fertilizer plant, Yang Mingzhi has long been mentally prepared, and he listens attentively.

Ivanov immediately sat down and explained the various problems that exist in the mass production of fertilizers.

First of all, the focus of the problem is on the equipment, and at this moment Yang Mingzhi is still holding the document in his hand. Ivanov said: "The methods of producing urea, ammonia and ammonium nitrate are all the same, the problem is to industrialize small-scale manufacturing, so the bottles and cans in the laboratory must be enlarged, the containers must be turned into cylinders, and a large number of steel pipes are needed." We don't have these things right now! ”

"I've thought about all these issues, you don't have to worry." Yang Mingzhi said confidently, "The Rigushkov in the arsenal can do all kinds of equipment you need. ”

"But isn't it cast iron that they produce the most? I need steel! Only steel can withstand high temperatures and pressures. ”

"Of course he can smelt steel." Yang Mingzhi said firmly.

In fact, as he said, the fuel used in the arsenal is charcoal, and its calorific value is actually a little higher than that of coking coal, which is a good material for steelmaking. But because it is only to make ammunition, it does not need to be refined and smelted, as long as it meets the needs. In addition, the current increase in production has to ignore the quality, and the metal returned to the furnace is mixed with a lot of impurities, and he did not find a way to separate them, so he created a batch of "brittle bullets", which unexpectedly made such ammunition more lethal.

But there is no problem in allowing him to produce steel, he just needs to strictly control the production and separate the impurities and excess carbon.

After listening to Yang Mingzhi's explanation, Ivanov breathed a sigh of relief, in his opinion, the most important thing to solve of all problems is the equipment problem.

"That Rygushkov, when the war is won, I think he can be an engineer, and he used to be the chairman of the collective farm Soviet (village head), which is really condescending." Ivanov sincerely wished that person, and now the problem that needs to be solved urgently becomes the next one.

"The production of urea and ammonia has to be done chemically to be mass-produced, and the way to do that is to do a special chemical reaction of carbon monoxide and hydrogen, because we have to have a lot of both," he said. The best way is to use coking coal, which can now be used to make do with charcoal, but the deputy division commander must understand that the hydrogen content in charcoal is very low, and this hydrogen is mainly derived from hydrocarbons. ”

Yang Mingzhi nodded, he still knew about this knowledge.

In China in the fifties, two of the 156 Soviet-aided projects were fertilizer plants. The raw material for its production is coal, and the scale is only 60,000 tons per year.

Later, China improved the process and adopted the method of synthesizing ammonia with petroleum as raw material, and the introduction of oil was almost a hodgepodge of various olefins, and the output efficiency was naturally greatly improved.

The deputy division commander is also an intellectual who understands chemical industry, and when Ivanov saw him nod, he continued: "Let's engage in synthetic ammonia, which is an industry with high energy consumption. In addition, the chemical reaction of ammonia synthesis is very simple, but the process is still very complicated to achieve industrial industrialization. On the one hand, it is troublesome to outwit the raw gas, and the process is a bit long, the last time I made 500 grams, I ordered the entire laboratory to shut down the production workshop, and everyone put into ammonia production.

On the other hand, ammonia is produced in a high-temperature and high-pressure environment, so I need the right equipment.

And the most critical aspect is the issue of raw materials. To produce one ton of ammonia, I am afraid that ten tons of charcoal will be consumed in the process, and eventually dozens of tons of logs will be consumed. I haven't counted the manpower and material resources consumed in this.

For the sake of our fertilizer, we have to mobilize a lot of people to put it in! Of course, the final product is ammonium nitrate, which can be used as a fertilizer, but also as an excellent explosive. The input put into it for the production of it is probably unbearable for us in Novgomel. ”
