Chapter 182 Hou's Alkali Production Method

The next day, Cheng Nuo bought a bunch of gifts and planned to take them to Tianjin as a guest.

Accompanied by the sound of creaking wheels, Li Laosan, who was riding a bicycle, turned around and said with a silly smile: "Sir, you bought so many things, won't it sink when you carry it on the train? If it's me, Lao Li, I'm sure." After arriving in Tianjin by car, it’s more convenient to buy it with money, isn’t it?”

Cheng Nuo patted the pastry gift box under his feet, and said with a smile, "There are some processes that cannot be omitted, just like this gift-giving, will Mr. Fan lack this thing? Naturally, there is no shortage of wealth, so let's not say it is Giving a gift is more like giving a gift.”

Li Laosan looked back, frowned and thought hard: "Just like what Mr. Guo said, sending chicken feathers from thousands of miles, the gift is light... the ceremony is light, anyway, sir, you understand what I mean."

"Haha, what kind of chicken feather is that? It's a goose feather." Cheng Nuo laughed and explained, "It's not impossible to give chicken feathers, but it's not a gift, but a gift." It’s a chicken feather letter.”

"Fortunately I didn't let Goudaner come with me, otherwise the father would be laughed at by his son." Li Laosan blushed, and relied on his strong psychological quality to survive: "But sir, such a good business, Why do we have to find someone to help, isn't it just sending money out for nothing?"

Cheng Nuo smiled and shook his head: "Because it's not our style to fight alone, especially in this turbulent world, one more friend means one less potential enemy, and the gains are far more than superficial money."

Out of curiosity, Li Laosan wanted to continue asking, but when he was about to speak, he suddenly thought of Cheng Nuo's next words. He probably had reached a stage where he didn't understand. It would take a lot of brains to understand, so it's better not to ask.

"My boy is not young anymore. Call him over later to be your school boy, sir, and let him study hard by your side. Don't be like me, who spends most of his life in a daze and doesn't know anything." Holding the handlebar with his hand, he said while wiping the sweat from his brow.

Cheng Nuo just smiled at this, neither agreed nor opposed.

Close your eyes and rest your mind, let the hustle and bustle of the street pass by your ears, not only will you not feel anxious, but you will feel the reality of living in the world.

But I think Li Laosan has asked this question, presumably there are not a few comrades in the Academy of Sciences who have the same idea.

It's okay if these people only keep their opinions, but if they dig into the horns and go astray in the future, it will be a huge loss to everyone.

Cheng Nuo simply untied all these knots before leaving for Tianjin.

"Some people say that we have advanced alkali and acid production technology, why can't we set up a factory to make money by ourselves like we mastered the match technology before, and all the profits can be used for ourselves, continue scientific research, and form an industry-university-research institute forever. Wouldn't it be beautiful to continue the cycle?"

Sure enough, some comrades nodded subconsciously, obviously agreeing with this point of view.

Cheng Nuo was not in a hurry to refute this, and walked down from the rostrum to the crowd, and said with a smile: "The British classical economist has an economics book that took ten years of hard work. I don't know if you have heard of it. If you have , Is there any comrade who is willing to stand up and speak.”

As soon as the words were finished, a handsome young man stood up: "The title of the book is "A Study of the Nature and Causes of National Wealth", or "The Wealth of Nations" for short. It mainly talks about the nature and source of national wealth."

Cheng Nuo raised his eyebrows, satisfied with the answer: "It's concise and concise, and it sums it up very well. By the way, what's your name?"

The young man didn't expect the dean to like this answer very much, and he spoke incoherently excitedly: "Hi Dean, I... My name is Fang Xianting, I happened to see this book in a bookstore, and after reading it several times, I finally put it away." I know it by heart, if you ask anything else, I might not know it.”

"It's okay. For some people, it's enough to read this kind of book for a lifetime." Cheng Nuo raised his hand and asked the other party to sit down first, and asked, "Fang Xianting, that's a good name, but it should be our first time." Let's meet, you don't seem to be from our Academy of Sciences, do you?"

Hearing this, Fang Xianting, who had been sitting down, felt as if a spring had been installed on his buttocks, and immediately stood up again, blushing: "Dean, I'm sorry, I'm just a worker from Shanghai who happened to pass by the auditorium When I heard you giving a lecture, I couldn't help but slipped in, I'm sorry to disturb you, so I'll go out now."

After saying this, Fang Xianting really packed up the pen and paper, and was about to leave with his head hooked.

Although this person has not yet become a master of economics, since they are all sent to their door, how can they let him go.

"There is a lack of a clerk in the reference room. If Comrade Fang doesn't mind, he can work with us to get used to it first. What do you think?"

Fang Xianting was about to walk to the last row. When he heard this, he immediately raised his head, his eyes were shining brightly: "I can really?"

Cheng Nuo rubbed his nose and said with a smile, "Why not?"

Fang Xianting, who was born as an apprentice, is also a legend. He completed all the courses of the University of Wisconsin Preparatory and the Department of Economics of the Business School in three years. In the four years after receiving his bachelor's degree, he successively obtained a master's degree and a doctorate.

After returning to China, he actively participated in the construction of the country and became one of the most successful people in the study of Western economics in China at that time. Together with Ma Yinchu and others, he was also known as the four major economists of the Republic of China.

The reason why Cheng Nuo kept him was not only to cherish his talents, but also to find Jiang Jiangzuo a deputy.

After all, he had promised him a long time ago that he would arrange more assistants for him.

Back to the topic, Cheng Nuo stood on the podium again, looked around the entire auditorium, and said seriously: "The theory of national wealth that Comrade Fang mentioned, we will talk about it later when we have a chance. What I want to talk about today is Adam Smith's theory of monarchy!"

As soon as these words came out, everyone was shocked except Fang Xianting.

One must know that not long after Zhang Xun's restoration, and now he wants to publicly talk about the theory of monarchy, it really has to make people think too much.

However, Cheng Nuo on the stage did not give everyone a chance to think about it. After seeing the atmosphere in the auditorium being mobilized, he copied a passage from "The Wealth of Nations" on the blackboard behind.

"The monarch's duty is first to protect the safety of his own society from the violence and aggression of other independent societies."

"The second duty of the sovereign, to protect the people from any man in the community being insulted or oppressed by any other, is to establish the administration of justice."

"The third duty of the sovereign is to establish and maintain certain public institutions and works."

Throwing the chalk back on the table, Cheng Nuo patted the dust on his hands, and slowly introduced: "Considering that the UK where Adam Smith is located is a constitutional monarchy, we can directly understand it as a national government, which means that the government should be responsible for social and economic life. perform three important functions.

That is, the three functions of ensuring national security, maintaining social and economic order, and providing necessary infrastructure. The most important externally is to protect the country's commercial interests from infringement.

Common name - night watchman. "

Regardless of the fact that the West has always claimed commercial freedom, in fact, since the Second World Industrial Revolution, Western countries have gradually strengthened their intervention in leading industries that are related to the lifeline of the national economy, and introduced incentives for emerging industries such as electrical, heavy chemical, and automobile industries. Conservation or industrial development plans.

The most obvious of these is that the French state-owned economy accounts for more than 70% of the national economy.

Even our "good neighbor" Japan, where the heavy industry is rising, counts as one, and is basically dominated by the Japanese government. Not only government-run and government-business joint ventures rely on government investment, but private enterprises also seek policy support from the government. and funding.

Seeing that everyone in the audience was almost digested, Cheng Nuo said slowly: "Take the alkali in the acid-alkali industry as an example, we now use more than 3 tons of alkali every year, and 6/7 of it is foreign alkali. The heavy chemical industry is a typical capital- and technology-intensive industry, which cannot be separated from the intervention and support of the state."

After saying this, Cheng Nuo left the venue straight away, leaving everyone in the venue to continue the discussion.

As for the specific details of the cooperation, it is not suitable to talk about it in public.

For the rest of the day, after Cheng Nuo handed over the visiting card to Fan Xudong, he didn't go directly to the door. Instead, he started a chemical experiment in the aviation school office.

On the one hand, Fan Xudong had just filed a record with the Ministry of Finance's Salt Affairs Administration for the preparation of the soda plant, and he was required to check all kinds of work, and he had no skills at all.

On the other hand, Cheng Nuo also had the heart to improve the formula for making alkali himself, and investing in technology as a share was more real than any gift.

In fact, at that time, there were two industrial soda production methods in the world: one was the Lublin process, which was simple in technology but poor in quality, and the other was the Solvay process, which was complex in technology but good in quality and low in cost.

In this alkali-making method, ammonia, water, and carbon dioxide react to form ammonium bicarbonate, and then react with sodium chloride to obtain sodium bicarbonate and ammonium chloride. Sodium bicarbonate is heated and decomposed to obtain soda (sodium carbonate).

The Solvay method is also commonly known as the ammonia method for alkali production. One of its characteristics is continuous production. All the machinery and equipment in the entire process flow are connected step by step to form a complete system.There are seven main parts of the whole process, and production can only proceed if all seven parts are functioning properly.

If one part fails and the balance is out of control, production will be seriously affected, and accidents may even occur.Therefore, adopting this process requires high technology and strict management.

It's not that the country didn't think of adopting this method to change the soda production industry, and even spent tens of thousands of dollars to purchase the formula.

But after getting the formula, I found that this thing is not a panacea. The demand for salt is too great, and it is the main raw material for making alkali.

The ratio of soda ash to waste calcium chloride is 1:1, that is to say, for every ton of soda ash produced, one ton of waste calcium chloride is produced simultaneously.

The characteristics of my country's salt management are: the price of salt is as cheap as sand, and the salt tax is astonishingly high.Taking Tanggu as an example, sea salt is only 2 jiao per load, but the salt tax is 3 yuan per load, which is expensive and cannot be afforded by ordinary factories.

At present, the only way to solve this problem is to move out the Hou's soda production method in advance.

As soon as he said it, Cheng Nuo hurriedly arranged for Li Laosan to buy or customize chemical utensils, while he went to buy some chemical preparations.

Speaking of which, Mr. Hou Debang resolutely came back from studying in the United States and joined Wynn Soda Manufacturing Company precisely because of the invitation of Fan Xudong. After several twists and turns, he invented Hou's soda manufacturing method.

Now that Hou Debang is still studying in the United States, Cheng Nuo has already had this idea and implemented it, and he still feels a little guilty in his heart.

However, the matter is urgent, and it is used in advance to develop the domestic chemical industry. From a macro perspective, the advantages outweigh the disadvantages.

As for the personal aspect, it was reserved for Cheng Nuo's follow-up compensation.

Moreover, when Hou's soda production method was first created, Japan invaded and occupied Indochina and blocked the ports entering Sichuan. The construction of Yongli soda plant was also forced to stop, so Hou's soda production method was sleeping in a safe. Up to six years.

Such a long time is enough for the domestic industrial strength to reach several new levels.

As a junior high school chemistry knowledge, Cheng Nuo couldn't be bothered by this.

“NH3+NaCl+CO2+H2O=NaHCO3↓+NH4Cl”

After transcribing the chemical equations, he began to explore the process of making alkali.

Add ammonia to the salt-containing mother liquor and send it to the carbonization tower, pass in carbon dioxide to produce sodium bicarbonate crystals, filter the mother liquor to cool down, add salt to precipitate ammonium chloride, and then absorb hydrogen and send the mother liquor to the carbonization tower, and continue to circulate in this way to obtain soda ash and ammonium chloride.

As for the carbon dioxide, Cheng Nuo has also planned a long time ago, that is, to build a synthetic ammonia plant at the same time, and successfully use the carbon dioxide that was originally waste gas, which can greatly reduce the production cost.

It not only saves the trouble of calcium chloride in the residual waste liquid of the Solvay process, but also obtains the agricultural chemical fertilizer product ammonium chloride.

It is in line with Cheng Nuo's original intention of developing Sannong.

We must know that the fertilizer in this era is generally based on curium sulfate. Although this thing can significantly increase fertilizer and increase food production, it is actually very harmful to the environment. It increases soil acidity, destroys the soil aggregate structure, and is prone to diseases and insect pests. In the long run Look at the disadvantages outweigh the advantages.

No matter from which point of view, the Hou's soda production method is far superior to the Solvay method, and it can also combine the acid-base chemical industry together for a perfect match.

Looking at the white noodles, Li Laosan was amazed: "Sir, don't you know the way? How can you use a little bit of this and a little bit of that to make a little bit of alkaline noodles? You are too good."

Cheng Nuo said with a smug look, "Want to learn?"

Li Laosan nodded hurriedly: "I want to learn, I want to learn, my old Li wants to learn."

Cheng Nuo went up and threw the copied equation over, and said with a smile: "Whenever you understand this thing, you will learn it."

Originally, Cheng Nuo just wanted to use this method to let Li Laosan learn more other knowledge, but he didn't expect that because he couldn't understand, it led him astray.

"Sir, is this the talisman you cast the spell on? Is it really okay to pass it to me?"

Cheng Nuo was so angry that he directly supported his forehead, took over the chemical equation, and waved his hand to let the other party leave: "You can stay here if you are cool."

"Hey, sir, you are busy!"

"Come back, what were you doing here just now?"

"Oh, I almost forgot, that Mr. Fan Xudong asked someone to come over, saying that he would come to visit you personally in the afternoon."

　Recommend a book:

　　"I am the underground lord of the underworld" is the underground lord, the ancient underworld lord.

　　Tang Ping traveled through the world of immortals and heroes, and became an insignificant underground master with the help of the ancient relic "Gaodi Ce of the Eastern Han Dynasty".

　　Evil spirits thrive and ghosts run rampant.

　　This is a chaotic world of myths and monsters.

　　Undead feathered people, strange beasts from mountains and seas; psychic alchemists, witches and demons.

　　As the ancient underground lord, Daqian's first priesthood.

　　With the strategy of improving proficiency, Tang Ping could not move, built walls to accumulate food, cultivated the divine way, refined supernatural powers, wrote secret deeds, and transformed into priesthood.

　　The flowers bloom and the sun sets, the years pass quietly, and the eternity is full of mist.

　　I am the Lord of the Underworld, living forever in the world.
