my scientific age

Chapter 161 I am happy!
Confused.

sluggish.

Unbelievable.

Lin Wan was extremely shocked, all kinds of emotions surged in her heart, she couldn't believe what she heard.

She is not as ignorant and ignorant as other students when it comes to the rare and unpopular basic inorganic chemical industry. On the contrary, Lin Wan knows a lot of chemical knowledge and is very aware of the importance of sulfuric acid as an industrial raw material!
As the most important chemical raw material in modern industry, the importance of sulfuric acid relative to modern industry is just as people cannot live without three meals a day.

If you don't eat, you will be hungry.

Modern industry cannot function properly without sulfuric acid.

The production of steel requires sulfuric acid, and the production of fertilizers, medicines, and pigments requires sulfuric acid. In petroleum smelting and explosive production, sulfuric acid is the core key.

If the output of steel is a measure of the strength of a country's heavy industry, then the output of sulfuric acid is a measure of the strength of a country's chemical industry.

Steel and sulfuric acid are equally important.

And what is the concept of 22 tons of sulfuric acid per day in Yu Hua's mouth?
To give a real example, as far as she knows, the giant company in the chemical field of Tianjin Zhonghua Chemical Industry Co., Ltd., next door, is preparing to build an ammonium sulfate plant with an annual output of [-] tons in Nanjing, which officially started production in January this year.

Its annual output of sulfuric acid is 4 tons, and the daily output is about 109 tons. The technology and equipment are all from the United States.

With an annual output of 4 tons of sulfuric acid, Yongli Nanjing Ammonium Sulfate Plant has become the largest sulfuric acid factory with the highest output in the country.

Now, the seven-tower device Yu Hua said has a daily output of 22 tons and an annual output of 8000 tons, which is comparable to one-fifth of the capacity of the Yongli Ammonium Sulfate Plant.

A piece of equipment is equal to one-fifth of other people's factories?

God, do you want to exaggerate?
If a seven-tower device such as Yuhua is used, with the same scale of investment in the Yongli Ammonium Sulfate Plant, the sulfuric acid output will exceed [-].

And this was the reason why Lin Wan was extremely shocked.

If this seven-tower sulfuric acid production technology can be used by the organization...

In a flash, the whole person's breathing suddenly became heavier, and he only felt a little dizzy in his head.

calm down!

keep cool!

Lin Wan took continuous deep breaths, tried to calm down her emotions, quickly calmed down, and was not carried away by the huge temptation.

"I'm sorry, I've lost my way, but I have a question, can this seven-tower device really achieve a daily output of 22 tons?" Lin Wan stopped, stared at Yu Hua, thought for a while, and said with an expression on her face. With a solemn taste, he asked: "The American technical equipment introduced by Yongli Chemical Company has a daily output of about 109 tons."

Serious and serious, this is the most basic attitude.

Lin Wan was not carried away by the ultra-high output of the seven-tower device, even though she knew what it would mean if the organization had this technology.

The seven-tower plant with a daily output of up to 22 tons is very tempting, but its output is so high that it feels unbelievably high.

Lin Wan did not question Yu Hua's goal, but whether it could really be realized.

In fact, if it wasn't for Yu Hua's own words, if it were someone else, Lin Wan wouldn't believe it at all.

In the field of science and technology, China is extremely backward, and there is no basic environment. It is not easy for a certain field in China to catch up with the technological level of the West.

As for surpassing the West, that's too ambitious.

"Yes, if you believe me, in addition, from the perspective of rigorous naming, it should be called Yu's Seven Pagodas. After all, the tower method was not invented by me, and it is a bit sloppy to call it a seven-tower device."

With a smile on his face, Yu Hua nodded confidently and replied, "The technical equipment introduced by Wynn is a six-tower device, which has been eliminated in the United States. The current sulfuric acid production process has been upgraded to the principle of contact method."

There are currently three mainstream methods for sulfuric acid production, lead chamber method, tower method and contact method. The main raw materials are sulfur and pyrite, and the three methods are different.

The lead chamber method began in the seventeenth century and is the oldest method of preparing sulfuric acid. The principle is to use advanced nitrogen oxides to oxidize sulfur dioxide and generate gaseous sulfuric acid. Large scale and high cost.

The tower method is improved from the lead chamber method. In 1911, Austrian Opper created the world's first tower method device, which consists of a packing tower, a denitrification tower, an acid-forming tower, an oxidation tower and a nitrification tower. The volume is 100 cubic meters, and the seven towers are 700 cubic meters. Through the liquid phase, the sulfur dioxide is promoted to complete the nitrification reaction to produce sulfuric acid.

The entire reaction process only needs to be carried out in each tower, similar to the lead chamber method, but the output is more than double that of the lead chamber method, and the cost is low. Once it appears, it immediately replaces the lead chamber method and becomes the mainstream production process in the chemical industry. It is divided into five towers. , six-tower device and seven-tower device, the United States and Europe are currently using seven-tower device.

As for the contact method, this is the main method for the production of sulfuric acid in the modern chemical industry and is extremely suitable for large-scale production.

Yu Hua was not prepared to study the sulfuric acid production technology based on the contact method. First, the investment was too high, and second, the technology was too advanced. Once the technology was leaked to the Japanese, it would have catastrophic consequences.

Yu's Seven Pagodas.

Hearing these four words given by Yu Hua, Lin Wan nodded, her thoughts surging and she fell into silence.

silence.

Dead silence.

Now, everything that needs to be said has been said, and there is only one choice left for Lin Wan——

promise,

Still refuse.

With a smile on his face, Yu Hua was silent and did not urge.

The whole person turned a blind eye to the various eyes cast around him, quietly looking at the best angel investor whose face was constantly changing in front of him, waiting for the final answer.

Today's Lin Wan is dressed in plain colors, wearing the iconic Republic of China girl's dress, her eyes are full of aura, as quiet and elegant as a lotus flower.

Very beautiful.

"Is [-] enough?" After three seconds, Lin Wan, who was lost in thought, seemed to make a decision. A pair of eyes that were as clear and pure as gems revealed a brilliance, and stared straight into Yu Hua's eyes, the whole person didn't care. The eyes of other students in the school said in a straight voice.

The four eyes met each other, and there was trust in their eyes.

Lin Wan didn't know why Yu Hua made the leap from mathematics to chemical industry. The span between the two was simply bigger than the Yellow River.

One is biased towards theoretical foundations, and the other belongs to practical applications.

In actual technology development, there will be countless problems encountered, but Lin Wan chooses to believe in Yu Hua's talent, talent, and academic level.

Perhaps, Yu Hua can really develop excellent technology that Westerners can't match.

If this seven-tower device is as Yu Hua said, the output can exceed twice the performance of Western sulfuric acid production equipment, not to mention eight thousand oceans, even if it is smashing the pot and selling iron, she will support Yu Hua to develop it.

Money is very important, in front of advanced technology, it is not worth mentioning.

Which is lighter and which is heavier, anyone who thinks with his toes can tell the difference.

As for the return, Lin Wan believed that Yu Hua would not let her down.

"Enough, but the more oceans there are, the faster the R&D speed. If you lend me 20 oceans, it will take a month and a half to finish. If you lend me [-] oceans, it will take about [-] days." Hearing this expected answer , Yu Hua smiled at the corner of his mouth, blinked at Lin Wan, and joked.

Yu Hua was very happy, but Lin Wan did not disappoint him.

"..."

Good guy, Lin Wan rolled her eyes when she heard the 5000 yuan ocean tree, thinking that the results would be produced in about 20 days, she took a deep breath: "Then lend you [-] yuan, the sooner the better, I will try my best to raise money." Funds, how long do you want?"

"The day after tomorrow, we will talk about technology research and development and other matters later. I will give you a technical feasibility report at that time, and I may bring you in to help you." Yu Hua responded.

Lin Wan nodded, and then asked, "Okay, Yu Hua, can I ask one last question?"

"Of course, you ask." Yu Hua smiled.

"Why did you ask me to borrow money? I believe you are very aware of the value of this technology." Lin Wan asked in silence for two seconds.

why?
Why borrow money from her, not someone else?
Even if Yu Hua wanted to borrow [-] oceans, or even [-] oceans, it seemed a huge amount. In fact, as long as the news was released, there would be no idea how many capitalists and dignitaries in the country would be willing to lend money to Yu Hua.

This is a cutting-edge technology that can monopolize the entire Chinese sulfuric acid market.

The so-called 'borrowing' is actually an invitation.

"Two reasons, one, I happened to meet him, and who can borrow it or not, and two, I'm happy." Yu Hua heard this, blinked his eyes, and said with a smile.

After he finished speaking, he turned around and left, heading towards the cafeteria.

Lin Wan's face was full of confusion: "???"

Who to borrow or not?
Are you happy?
Seeing Yu Hua's unrestrained departure, Lin Wan was extremely speechless, even a little dumbfounded.

"Jin Yu." At this time, Yu Hua, who had already walked some distance, suddenly stepped forward and called out to Lin Wan.

"What?" Lin Wan raised her head.

"Revitalize China, let's encourage it together." Yu Hua said loudly.

Lin Wan was stunned for a moment, and Zhuang nodded: "Let's encourage each other."

"Let's go to dinner." Yu Hua smiled and waved his hand, walking back and forth.

"The seven-tower device with a daily output of 22 tons... Yu Hua, thank you for asking me to 'borrow money'. I will definitely collect [-] oceans as soon as possible." Lin Wan stared at Yu Hua, who was gradually walking towards the cafeteria of Chongde Middle School. The content of the conversation just now echoed in his mind, he took a deep breath and thanked softly.

thank.

Thanks from the bottom of my heart.

Although [-] oceans is a huge sum of money for the organization, Lin Wan is still very grateful to Yu Hua, because once the technology of Yu's Seven Pagodas is successfully developed, it will enable the northern Shaanxi base to have a basic inorganic chemical industry foundation, which will greatly increase the Level up the war potential of the entire base area and the Eighth Route Army.

Sulfuric acid, meaning gasoline and explosives.

As for the importance of gasoline and explosives, there is no need to say much.

At this moment, the whole situation can be called the highest level of borrowing money, not only making people agree, but also making people thank you for borrowing money.

Outside the school building, the sun is shining.

Lin Wan, who was bathed in sunlight, headed towards the dormitory building of Chongde Middle School. While it was still early, she wanted to quickly write a letter signed by herself and hand it over to the higher-level organization.

……

Tianjin city, suburban manor.

"[-] Oceans..." The 'professor' with a refined temperament revealed his body, the corners of his mouth twitched, and the right hand holding the entire letter was trembling slightly.

The reason for the trembling is nothing else, one word, money.

Lenin is above, where does he have to collect these fifteen thousand oceans?
It is a well-known thing in the world that the team is poor. If you borrow a thousand and eight hundred, there is no problem.

And that's a full fifteen thousand!It's not one piece of five, the total reserve funds of the entire Red Northern Department and its various branches and organizations add up to just over [-] oceans.

Baby, it's just dying.

The most important thing is that this money has to be borrowed!
Borrow eight thousand?
No!

Must borrow [-] kind!

Looking at the envy-inducing description and estimated output of the seven-tower device on the letter, the professor who has experienced the Long March and all kinds of dangerous battles has never been so embarrassed as he is now, mother, it's really a penny hero man.

With his right hand, he took out a cigarette from Zou Baba's pocket and lit it. Professor Liu took a deep breath and exhaled white smoke: "In the past, our team used to pay the people IOUs. Now, let's discuss how to raise money for him."

To be honest, it is really unreasonable, borrowing money to borrow money from the poor, he can remember the actions and name of Comrade Qingluan, a good friend.

Yu Hua, student, scientific research genius, formerly known as Yu Hua, on International Labor Day on May 1937, 5, borrowed money from Comrade Qingluan in the north of my country to do technical research!
The number, fifteen thousand! ! !
