Go back to the past and be a schoolboy

Today's Yongli Soda Plant, even if it is up and down, will be squeezed dry by people.

Fan Xudong still didn't want to show it in front of his friends, especially since he was still the center of the topic.

Announcing the reason at this time is slapping a friend in the face and making him look bad.

Quietly hiding this negative emotion, Fan Xudong tried his best to soften his facial lines: "It's good to make acid, so that the acid, alkali, and salt foundations of the chemical industry are all laid down. No matter what you do later , our confidence is also stronger.

However, making acid is not as easy as making alkali. Do you have any ideas in this regard? "

Cheng Nuo closed the door, walked to the rostrum, opened the curtain in front of the blackboard, and picked up chalk to write and draw on it: "Actually, thanks to the formula I wrote before, while making alkali, we also Can make something else."

The originally familiar chemical equation looked a little strange at this moment.

"Tell me, I'm a little confused for the time being." Fan Xudong frowned and pinched his chin in puzzlement.

"The first step is to continue to build an ammonia plant." Cheng Nuo wrote on the blackboard while explaining: "Our current soda production method is mainly divided into two processes. The first process is basically the same as that of Solvay. The alkali making method is the same.

That is, ammonia is passed into saturated brine to form ammonia brine, and then carbon dioxide is passed into to form sodium bicarbonate precipitation, which is filtered and washed to obtain tiny crystals.Then calcined to obtain soda ash product, the filtrate is a solution containing ammonium chloride and sodium chloride.

The second process is a bit different, and ammonium chloride crystals are precipitated from the filtrate containing ammonium chloride and sodium chloride.Ammonium chloride is more soluble than sodium chloride at room temperature.

The solubility at low temperature is smaller than that of sodium chloride, and the solubility of ammonium chloride in a concentrated solution of sodium chloride is much smaller than that in water, so under low temperature conditions, add fine powdered ammonium chloride to the filtrate Sodium chloride, and pass through ammonia gas, can make ammonium chloride crystallize and precipitate separately.

After filtering, washing and drying, the ammonium chloride product can be obtained. At this time, the filtrate obtained after filtering out the ammonium chloride precipitation is basically saturated with sodium chloride and can be recycled and used..."

It's okay not to talk, but Fan Xudong was even more confused after speaking: "Wait a minute, except for the salt, where do you get all these raw materials? Even if it is recycled, his share will not be so small, right?"

After asking the question, Cheng Nuo's writing on the blackboard was almost finished. He patted the dust on his hands, and said with a smile, "So let's build a synthetic ammonia plant first, and use the carbon dioxide and ammonia produced in the synthetic ammonia to produce carbonic acid." sodium hydrogen.

After the heavy alkali is filtered out, the mother liquor is recycled by crystallization method to analyze ammonium chloride, so that the utilization rate of sodium chloride is improved, and the by-product ammonium chloride is a kind of chemical fertilizer, not calcium chloride which is of little use. "

Fan Xudong looked at the chemical formulas on the blackboard and said thoughtfully: "That is to say, if we can really follow your steps in the actual process, it will not only improve the utilization rate of salt, shorten the production process, but also Reduce the pollution to the environment and reduce the cost of soda ash?”

Cheng Nuo snapped his fingers: "Yes, that's what it means. Right now, we need to import curium sulfate from foreign countries for our chemical fertilizers. Not to mention the high cost, we may not be able to buy it. Even if we can buy it and use it well, it will take a while." In a few years, the land will be polluted and cannot be planted, which is far worse than the reality of ammonium chloride.

Although it is not suitable for use on acidic soil and saline-alkali soil, chlorine can not only inhibit the nitrification of rice fields, but also facilitate the formation of rice stem fibers, so it is very good for planting rice. "

In layman's terms, it is the joint production of soda and ammonia, which produces both soda ash and ammonium chloride.The raw material is still table salt, but basically no limestone is used, and a synthetic ammonia workshop of a corresponding scale is needed to support it, thereby improving the utilization rate of raw materials.

It eliminates the discharge of waste, reduces the consumption of experiments and energy, and makes full use of the carbon dioxide emitted by the ammonia plant, turning waste into treasure, saving the consumption of limestone, and killing many birds with one stone.

The more Fan Xudong thought about it, the more he felt that it was feasible, and immediately clapped his hands and applauded: "Okay, I think it is quite feasible. At present, the domestic fertilizer market is basically dominated by foreign companies. I have long been unhappy with them."

Since ancient times, although farming seems to be very simple, as long as you have hands, how to achieve a good harvest is not an easy task.

Even in Cheng Nuo's era, apart from living expenses and taxes, the most important cost of farmers in production was fertilizer. According to the Bank of China report, fertilizer accounted for one-fifth of farmers' total expenditure, and the fertilizer market was quite huge. However, this market is increasingly segmented by chemical fertilizers.

Even if the price rises at this time, the price of one catty of ammonium sulfate is equal to the price of two catties of rice, but at least it can increase the production of three to four catties of rice.

Farmers can still distinguish this simple account.

As for problems like pollution, they seem insignificant in the face of a full stomach.

No one can escape the old road of pollution first and then treatment.

Cheng Nuo was very emotional about this situation: "For a long time to come, the importance of food will be particularly prominent. The ammonia fertilizer produced in our soda production is a great thing for both ourselves and the people. , It is far from enough to rely on manure alone, which is also the first thing we have to consider after the successful alkali production."

Fan Xudong nodded in agreement, but after reviewing the cause and effect, he suddenly recalled: "I remember that when you came here just now, didn't you want to make acid? Get out of the old way of making alkali? Besides, compared with making alkali, synthetic ammonia is not easy at all.”

Cheng Nuo smiled: "Okay, Xudong, you still found out, because synthetic ammonia is the key to our acid production."

Fan Xudong frowned: "Is there such a relationship between synthetic ammonia and acid production?"

Cheng Nuo erased the chemical equations on the blackboard. Fan Xudong stomped his feet anxiously when he saw it: "No, why are you erasing it? I haven't understood it yet."

"Because it's already in my head, I just took it out and pushed it down again." Cheng Nuo smiled, pointing to the new equation and said, "The tentative way to synthesize ammonia right now is to extract hydrogen and nitrogen from air and water to synthesize ammonia." .Ammonia oxidizes to generate nitrogen dioxide, which is then absorbed by water to obtain nitric acid.

As for hydrochloric acid, the most important thing we need right now is salt. Later, we can use electrolysis to produce hydrochloric acid and caustic soda. Let me think about the specific operation, and the problem is not too big.

The final sulfuric acid is simpler and can be solved by using the lead chamber method, but the specific aspects may be more troublesome. After all, sulfur dioxide and some catalysts are needed, but after we have laid the chemical booth, all these will not be a problem. "

In fact, Cheng Nuo said that if these three main acids were according to his preferences, regardless of the actual conditions, hydrochloric acid must be developed first.

For nothing else, it is because it is the main material of monosodium glutamate, which is what we often call monosodium glutamate.

At this time, Japan named MSG Ajinomoto, and it is relying on it to make a lot of money all over the world.

The raw material hydrochloric acid cannot be produced in China, and we have to buy it from Japan. It takes 4 taels of silver to buy 50 catties of hydrochloric acid, which is staggeringly expensive.

Through Cheng Nuo's detailed arrangements, he has properly arranged the chemical industry layout in the next two to three years. All that needs to be done according to the plan is to lead the innovation of the domestic chemical industry.

Of course, right now we have to break through this level first.

Looking at Cheng Nuo, who was full of himself, and thinking about those small shareholders holding back, Fan Xudong wished he could give everyone a hard kick.

It's really not enough, and there's more than enough failure.

But paper couldn't contain fire after all, especially when Cheng Nuo was full of expectations for the future, Fan Xudong didn't dare to lie.

After hesitating for a while, Fan Xudong gritted his teeth, and was about to tell the story: "Zhiyuan, in fact, we just came here before you came..."

Cheng Nuo didn't know what happened just now?

It's just that it's hard to speak out because of his friend's face, and he has already thought of a countermeasure, so there is no need to puncture the window paper to embarrass each other.

"Xudong, I remember that when our factory was first established, the two of us sat together with Mr. Zhang and signed a special agreement. Do you remember the general content of the restrictions on shareholder status?" Interrupting the words of his friend, Cheng Nuo pretended to be Just like everyone else, just ask another topic.

"Why do you think of asking this?" Fan Xudong asked habitually, but as soon as he finished speaking, his eyes lit up immediately.

Because in order to prevent traitors from betraying collective interests, Cheng Nuo proposed to add an additional sentence in the supplementary clause of the contract, that is, Wynn shareholders are limited to Chinese nationality from beginning to end. If there is any violation, the shares will be automatically returned at the original price.

Now these minority shareholders have just triggered this contract, which means that they are about to draw water from the basket.

Cheng Nuo patted his friend on the shoulder with a smile: "You must be constantly disturbed by it, Xudong, you have to think about it."

Fan Xudong, who was caught in the middle, hesitated: "But there are some shareholders who have been with me for so many years, and now they suddenly draw their salaries from the bottom of the pot, which is a bit too cruel."

Cheng Nuo said seriously: "In the future, there will only be more and more enemies in front of us. Do you dare to trust your back to these people?"

After saying this, Cheng Nuo turned and left to start the next journey.

Although the relationship between him and Fan Xudong is good at the moment, it is inevitable that there will be rifts between brothers when they do business, let alone their non-kinship relationship.

Now that Cheng Nuo had handed him the paper, pen and test paper, the other party's answer would determine the length of their cooperation.

Fortunately, in the end, Fan Xudong became ruthless and drove out all these small shareholders, leaving only the shares of Cheng Nuo and Zhang Jian.

Cheng Nuo knew why and asked, "Xudong, you're under a lot of pressure, right?"

Fan Xudong's spirit was much better than before. He sighed and said slowly: "The purpose of our business today is not to make a fortune. If we only want to make a fortune, we don't need to expend such effort. We are a revolution—a revolution against the economic oppression of the great powers. Life, the big waves wash away the sand, and all that is left is real gold."

Cheng Nuo toasted each other with tea instead of wine: "Don't worry, there will be more purer partners joining in the future."

Just as the two were emotionally preparing for the next step, a bad news suddenly came from outside.

"The Salt Administration is considering a proposal to levy a tax of [-] cents on every tan of salt used in Yongzhou".

If the bill passes, the cost of alkali is set to soar, enough to kill Wynn's prospects entirely.

Table salt is the main raw material for making alkali, and its operation is characterized by low salt price and high tax price.

If the problem of tax exemption for industrial salt is not resolved, the price of salt will increase by several tens of times, and China's soda industry will be out of the question when the foreign soda market is in surplus.

Therefore, Fan Xudong specially mobilized his contacts and asked the Changlu Salt Transport Envoy to transfer to the Salt Affairs Office of the Ministry of Finance to exempt him from the salt tax by franchise.

At that time, in order to fight for power and profit, the Beiyang government relied on betraying the country and borrowing debts to maintain its life. Yuan Shikai's aftermath loans were mortgaged by the salt tax.

According to the "Aftermath Loan Treaty" signed between the Beijing government and the United Kingdom, the salt tax should be used as collateral for China's borrowing from the United Kingdom; in order to effectively control the salt tax, the United Kingdom has to set up a "Salt Auditing Office" in the Salt Administration, and its power is entirely vested in the Salt Administration. British manipulation.

As a British, it is naturally impossible to watch your company be defeated by outsiders, and there will definitely be some stumbling blocks.

Sure enough, when Cheng Nuo inquired in detail, he found out that the Yongli factory was about to release alkali, and the British deliberately pressured the Salt Administration to make a decision of "paying a tax of [-] cents for every load of salt used by the Yongli factory".

What is even more infuriating is that HSBC also put pressure on Beijing to approve the privilege of making soda in China for Bu Neimen Company, otherwise it would refuse to borrow money.

HSBC really has bad water flowing in its blood since it was born, no wonder it took the initiative to sanction the chrysanthemum factory in its previous life.

Seeing this information, Cheng Nuo also secretly decided in his heart that after passing this level, he must clean up this ugly thing.

However, Fan Xudong's mood was not so good. He was so anxious that his mouth was full of bubbles: "Zhiyuan, once the salt tax rises, our Chinese soda ash will have no advantage at all. At that time, what can we do with it?" Bu Neimen confrontation?"

Cheng Nuo thought for a moment and felt that the situation was not as pessimistic as he had imagined. Even though the pressure from the government had come down, it didn't mean there was no room for relaxation.

"Xudong, have you ever heard of a saying called 'Build a new society and survive through competition'?"

"Hiss, where have I heard this sentence?" Fan Xudong patted his forehead, thinking hard.

"Haha, patriotism is not exclusive to you and me. Right now, patriotism, advocacy of domestic products, and revitalization of industries are intertwined and have already formed a strong social trend. Traditional politicians are not the only ones in charge of the government. There are also a large number of business people."

After a pause, Cheng Nuo continued: "What's more, the north and the south are struggling right now, the military and government expenditures are huge, the treasury is empty, and the finances are difficult. For people like the government, will our Zhonghua card benefit more if it falls, or does it stand up? "
