Coming to the office, Hou Debang drew a picture on the paper and briefly introduced to Chen Muwu the process of synthesizing soda ash by using Solvay's alkali production method.

He was not afraid that Chen Muwu would come to the soda factory to steal the teacher, and after stealing the core secrets, he would set up an alkali factory elsewhere and fight against Wynn.

First, although the chemical equation written in the textbook of the Solvay alkali production method is very simple, the specific operation process and production process are very complex, and the core data such as temperature and pressure cannot be accessed and mastered by Chen Muwu.

The second is that Hou Debang is not a person who likes to hide his personal interests.

After he thoroughly mastered Solvay's alkali production method, he wrote a monograph on alkali production and published it in the United States, making this method completely public, so that people all over the world could escape from the monopoly of alkali giants.

While listening to the explanation, Chen Muwu's brain was running rapidly, carefully recalling the knowledge he had learned from chemistry textbooks, as well as the various exercises he had done in the "Five-Year College Entrance Examination Three-Year Simulation".

When he heard Hou Debang mention in his introduction that the equipment purchased by Yongli Alkali Factory, in which the recycled items are ammonia and carbon dioxide, which produce waste calcium chloride, Chen Muwu finally remembered the difference between Hou's alkali production method and the current Solvay alkali production method.

"Mr. Hou, why did I see a lot of ammonia in the factory...... A bucket of Ammonian water? Can the Ammonia in this method really be recycled? Chen Muwu asked his question.

Ammonia, a transliteration of the English Ammonia, is now the old name for ammonia.

This title is too confusing, and I don't know when it will be changed to a convenient and concise ammonia word.

"This ......" Hou Debang seemed to be poked in the sore spot, "Theoretically, it can be recycled, but we have actually operated it several times, and found that whether it is Ammonia or carbon dioxide, the loss in each cycle is not small, so we still have to prepare a large amount of Ammonian water and limestone." Alas, I heard that there are already quite a few factories in Europe to synthesize Ammonia, and it would be nice if we had the money to build one sometime. ”

"It's true, with the synthetic ammonia plant, it is possible to provide not only ammonia, but also carbon dioxide. In this way, there is no need for ammonian water, and there is no need to burn lime. ”

Hou Debang mentioned in the introduction just now that the limestone used in Yongli Alkali Factory is produced from the stone mine in Beijiadian, Yanshan.

The carbon dioxide produced by the limestone after it is heated and burned at high temperatures is used as a supplement for the large amount of carbon dioxide lost in the alkali production cycle.

"How can you do it without burning lime!" Hou Debang really got on the set, "Without lime milk, you can't let Ammonia gas be recycled!" ”

Another product of burning, quicklime, is added with water to turn it into lime milk, which is then disposed of into a waste pond to produce recycled ammonia and a waste containing large amounts of calcium chloride and sodium chloride.

"Director Hou, forgive me for being a shallow learner, but I think that this kind of production method seems to have fallen into a strange circle.

"We say that we can recycle the two gases, but we still have to replenish them in production.

"Limestone is also wasted in large quantities, generating a lot of useless calcium chloride, which is cumbersome to dispose of.

"Since Ammonia is always going to be replenished, why not just discard the addition of lime milk to the waste liquid in the circulation?"

Chen Muwu finally tried to see the dagger.

Hou Debang seemed to understand Chen Muwu's implication: "You mean, just leave Amonia in the waste liquid?" But what is the use of rinium chloride? ”

Ammonium, now translated as monium, is later called ammonium, and rhinium chloride is ammonium chloride, which is another difference between the folk and modern transliteration.

"I think we can separate the rium chloride and use it as nitrogen fertilizer and apply it to the ground to help the crops grow. This kind of by-product that can be sold for money is much stronger than calcium chloride that is thrown away for nothing. ”

"Doesn't the application of rinium chloride make the pH of the land lower?"

"You can sell rhidium chloride to the south as a special fertilizer for paddy fields, and the running water and frequent rainfall can take away the chlorine well and prevent them from remaining in the soil."

Hou Debang pondered for a long time: "Hanchen, you have provided us with a new idea. It's just that if we are to finally realize your vision, we will need more ammonia than we do now.

"As far as I know, a set of synthetic ammonia equipment can be worth a lot of money now, the point is that there is no market, and even if you have money, foreigners may not be willing to sell it to you.

"Even our current soda production process was secretly obtained by General Manager Fan from foreigners at a great price."

Indeed, as Hou Debang said, in this era when a ton of soda ash and an ounce of gold are equivalent, foreigners will never give up the opportunity to make a fortune.

Chen Muwu knew that the synthetic ammonia factory was definitely the most high-end thing in the world in the twenties.

Although crude ammonia is also present in the product of coal after dry distillation, it is not half as efficient as a synthetic ammonia plant.

The advantage of this plan he gave is that it can cancel the lime kiln, and at the same time, it does not have to produce useless waste calcium chloride, but as Hou Debang said, in this way, it is necessary to purchase a larger amount of ammonia.

He didn't know what to comfort him, so he had to say a movie line: "There will be bread, there will be milk, everything will be fine." ”

……

Before leaving, Chen Muwu proposed it to Hou Debang, and when he came, he saw rust in the components of the reactor.

He advised Hou Debang to completely remove the rust, otherwise, it is likely to dye the white soda ash.

Rejecting Hou Debang's kindness to entertain him in the evening, Chen Muwu left the Yongli Alkali Factory while the sky was still bright, and returned to the cabin moored in the "Xinming" at China Merchants Wharf.

The "Heavenly Machine" has been inadvertently leaked out, but how long it will take to comprehend it depends on Hou Debang.

I hope that he, a genuine Columbia doctor, will have an inexplicable sense of familiarity in the face of his future research, and then speed up the research process!

Chen Muwu admires entrepreneurs such as Fan Xudong and Hou Debang very much, but if he is allowed to engage in industry and take the old road of industry to save the country, he will definitely choose to refuse without hesitation.

Now the Beiyang government is okay, at least Liang Rengong can help Fan Xudong exempt him from Haiyan taxes for decades, so that he will not be too constrained by money, and can devote all his body and mind to his career.

But after the city changed to the White Sun Flag, the chemical plant of the Wynn system began to struggle.

How did Fan Xudong die in the end?

After the victory of the Anti-Japanese War, he was bent on restoring the chemical industry and making Wynn bigger and stronger, so he applied for a loan of 16 million US dollars from the Export-Import Bank of the United States.

After a four-way campaign by his friend Chen Guangfu, the Bank of America finally agreed to the loan, but required a guarantee from the Nationalist government.

As a result, Fan Xudong sent countless reports to the Executive Yuan to apply for guarantees, and finally got a shocking news, Song Moumou, the premier, sent someone to spread the word that as long as he Song Moumou could become the chairman of Wynn, he would immediately assign the branch of the Bank of China in New York to sign the guarantee agreement.

Fan Xudong naturally rejected this shameless request without hesitation, and then the Executive Yuan immediately sent back the reply of "not approved".

The father of the poor generation of chemical industry was in a hurry and fell.

Even Fan Xudong ended up like this, and who ruthless people who are not surnamed Jiang, Song, Kong, and Chen can make their business bigger and stronger in the People's Republic of China without being remembered by others?

Of course, Chen Muwu is indeed surnamed Chen, but his Chen is Yu Chen, but he is not the Yu Xingchen, so it is not good.

The more he thought about it, the more upset he became, and he had no appetite, so he only let the tea room send two pork cutlets indiscriminately, and after eating, he lay on the bed and fell asleep.
