Chapter 21: Grand Concept

"Wanrong, are you saying true?" Chen Laoshi was a farmer and was most concerned about fertilizer. He reacted first and asked, "Wanrong, what you said is better than singing, isn't it a lie, right?"

It is really difficult to ask him to believe that this is true at once.

Phosphorus fertilizer is a type of modern chemical fertilizer. Since its emergence, it has played an extremely important role. If there is no phosphorus component, would modern agriculture be so high?

Chen Wanrong affirmed: "Dad, how can I speak nonsense about such a big deal?"

"That's the reason! If there is such a fat, then farmers will wake up when they fall asleep!" Chen Laoshi's eyes were very bright, staring at Chen Wanrong and urged: "Wanrong, since there is such a good fat, hurry up and make it. Dad goes to the whole piece of land to try it. If it is really useful, you tell the emperor that in the Tang Dynasty, all the people need to use it. With the fat, the people can have a full meal."

No one expected that Chen Laoshi, who was quick-talking on weekdays, had such a broad mind. Everyone was stunned. Seeing everyone looking at him, Chen Laoshi felt embarrassed and said embarrassedly: "Wanrong, did Dad say the wrong thing?"

"Dad, you're right, you're saying it very well!" Chen Wanrong praised and said in a word: "Although this fertilizer is good, it takes some time to make it. First, you have to make it. Without sulfuric acid, this fertilizer is just a talk."

"Then tell the Taoist priest how to do this sulfuric acid? Such a big deal cannot be put on, the faster the better!" Chen Houshi urged.

Chen Wangshi rarely agreed with his statement: "Yes! Wanrong, my mother is a farmer and knows how important fat is to farmers. Just talk quickly, let's listen."

They don’t understand chemistry, and it’s just a waste of time. Chen Wanrong responded: “Master Taoist, there are many ways to make sulfuric acid, and we can only use the most suitable method for us at present.”

The best one is not as good as the most applicable one. This is impossible, and the Tang Dynasty had that condition.

Sima Chengzhen nodded and said, "My friend, please speak, please listen."

Chen Wanrong talked about the use of sulfuric acid for a long time, and the conditions were unexpectedly wonderful uses. The relationship between sulfuric acid was too important. Sima Chengzhen was very excited and his ears were erect.

"There are two kinds of raw materials for making sulfuric acid, one is sulfur and the other is saltpeter ore. If there is no sulfur, use pyrote ore." Chen Wanrong began to explain the method of manufacturing sulfuric acid: "It is necessary to make an incinerator, put sulfur and saltpeter ore together to incinerate. The generated gas enters the denitrification tower to remove nitrogen oxides. The processed gas enters the acid tower, and then passes the nitroscopic tower to obtain sulfuric acid."

Chen Wanrong's production method is different from the lead chamber method, nor is it a contact method. The problem with the lead chamber method is that it is low efficiency and low sulfuric acid concentration. Furthermore, lead is too expensive and has high cost. It is precisely because of this that the lead chamber method is replaced by tower method.

The lead chamber method is the oldest method of sulfuric acid production, which has existed for more than a hundred years. The reason why it is called the lead chamber method is because the main equipment for producing sulfuric acid is a hollow square lead chamber, which is named after it. The principle is the same as the tower method, which uses nitrogen oxides to oxidize sulfur dioxide to produce sulfuric acid.

The sulfur dioxide obtained by incineration is about 300 to 500 degrees. After removing nitrogen oxides through the denitrification tower, the main ones are sulfur dioxide, as well as nitrogen oxides, oxygen and water vapor. The sulfur dioxide obtains sulfurite acid, not sulfuric acid, so further oxidation is required to obtain sulfur trioxide. This step is completed in the lead chamber.

In the lead chamber, sulfur dioxide is fully oxidized to form sulfur trioxide, and then absorb water to form sulfuric acid. This process is very slow. The fundamental reason is that the acid mist is formed, which takes a long time to condense into liquid droplets and fall into the bottom of the lead chamber. Therefore, multiple lead chambers are generally connected in series to improve production efficiency.

This way, the demand for lead chambers is greater and the cost is higher. At the same time, the sulfuric acid concentration produced by this method is low and cannot meet the needs of the industry, which forces improvements to be made, which leads to the emergence of tower methods.

The so-called tower method is to replace the lead chamber with a fillered tower equipped with filler. The advantage of this method is that, first, a large amount of lead is no longer used, which reduces the cost. Second, the filler is used, which has the "cutting" effect and improves efficiency. Third, the sulfuric acid concentration obtained by this method is relatively high.

The sulfuric acid concentration obtained by the lead chamber method is 65%, while the tower method is increased to 76%, which is a huge improvement.

The sulfuric acid concentration obtained by the contact method is higher. The reason why Chen Wanrong abandoned the contact method is because the contact method requires the use of catalysts. With the current conditions, the creation of a catalyst can only be considered, and it is unlikely. After a while, when the conditions are ripe and the catalyst is created, it is still possible to use the contact method.

Sima Chengzhen said with some disappointment: "My friend, I heard you speak so amazingly, but I thought it was so difficult to make sulfuric acid. I didn't expect it. It was so simple, it was over in just a few words."

"Simple? Sulfuric acid is a systematic project, but not simple." Sima Chengzhen judged the difficulty by how much he spoke, which was really a big mistake. Chen Wanrong hurriedly said: "Master, I'm just briefly talking about it. It's very difficult to do it, and it's not inferior to making a steam engine. There are many equipment in it, and we have to talk about it one by one."

After hearing Chen Wanrong's serious statement, Sima Chengzhen couldn't help but dispel his contempt and listened carefully to Chen Wanrong's explanation. The process of the tower method is not difficult, it is to incinerate first, then enter the denitrification tower to remove nitrogen oxides, then enter the acid tower, and finally enter the nitrogen absorption tower.

There are only three steps, and each step has many key points. One by one, it took a long time until Chen Wanrong was dry and finished.

When Chen Wanrong finished the explanation, Sima Chengzhen did not speak, but couldn't stop blinking his eyes and asked: "My friend, why should we set up a denitrification tower in front and a nitrification tower in the back?"

This is a key question, and I asked the point. In his reaction, Chen Wanrong praised it: "Nitrogen oxides actually play a catalytic role and should be recycled as much as possible. From an ideal perspective, nitrogen oxides are not lost, but in fact there is still some loss, so saltpeter ore is needed to be used to supplement it."

The original lead chamber method did not have a denitrification tower in front and a nitroscopic tower behind, and the recycling of nitrogen oxides was not achieved, which was relatively high. With a denitrification tower and a nitroscopic tower, nitrogen oxides could be recycled, which could reduce costs. Of course, the key is to help increase the concentration of sulfuric acid.

"Happy! Happy!" Chen Wanrong's explanation was far beyond Sima Chengzhen's imagination, and he was very excited: "My friend, the military weapon supervisor has something to do again. I am unable to do such a big thing. In my opinion, Master Ye and the others should be invited, so let's discuss it carefully."

If Li Longji hadn't asked Chen Wanrong to supervise the army, Chen Wanrong wouldn't have silly put so many things on Sima Chengzhen. It would be impossible for Chen Wanrong to not do this. After all, there was no bottom line when this battle would be over. If it took too long and the chemical industry was missed, it would be a big loss.

Chen Wanrong agreed with this proposal, but he still had concerns: "Master Taoist, it's good. But today is the New Year, so it's not good to do this, right?"

"Such a good thing is related to the world. I think Master Ye and the others will come happily after hearing the news." Sima Chengzhen was in a good mood and joked: "My friend, don't you feel sorry for the money for drinking?"

"Haha!" Chen Wanrong laughed and said, "That's it!"

"Qingxu, you go and tell Master Ye and the others immediately and ask them to come over." Sima Chengzhen ordered his disciples to do things without waiting for Chen Wanrong to speak.

After hearing this for a long time, Qingxu and the other two were very excited. They were extremely enthusiastic about this matter. Without saying a word, they set off immediately.

In any case, Chen Wanrong still has to take care of the meal. Once the three of them went, Zheng Qing had to prepare the food and drinks. Chen Wangshi rushed to go: "Wife, please help Wanrong, I will be the one who is in charge. Let's go!"

Although it was the Chinese New Year, the servants in the mansion were still there, and Chen Wang just needed to give him an order.

Chen Wanrong, Sima Chengzhen, Zheng Qing and Chen Zairong sat around to answer some questions for them. Sima Chengzhen was a famous alchemist in history and had an amazing understanding of chemistry. Naturally, his questions were beyond words, and they often asked the key points. Although Zheng Qing was not as interested in chemical engineering as Sima Chengzhen, the questions he asked were not bad.

Only Chen Zairong asked questions as if they were asked by a primary school student. However, this is understandable, after all, he has never been involved in chemical engineering.

"Haha! My friend, if you have something good, it's not interesting to not tell me." A loud voice sounded, and the tick sound of a crutch hitting the ground.

As soon as he heard this, he knew that Ye Tianheng had arrived. Chen Wanrong stood up and saw Ye Tianheng piercing in, wearing new clothes and smiling.

"Master Ye, please sit down." Chen Wanrong hurriedly greeted.

"Just call Master Ye, forgot me?" Kou Yibing's voice sounded and he stepped in.

Before Chen Wanrong could greet him, Liu Huaide came in again and accused Chen Wanrong: "General Chen, how can you say something good in the New Year? Isn't this intention to not let someone celebrate the New Year?"

The voice of the monk and his party sounded: "If Master Liu thinks it is not worth it, you can go back and we won't stop him."

Liang Lingzan came in and took the conversation: "Master Liu, we discuss good things while drinking. Where are you looking for this fun? If you want a wife, please come back."

"I'm just talking about it, do you need to run to me?" Liu Huaide muttered dissatisfied.

Chen Wanrong called everyone to sit down, and Zheng Qing and Chen Zairong were busy delivering tea. Chen Wanrong explained: "Everyone: I didn't expect some things. After a while, I will leave Chang'an. No one can tell when I will come back. Therefore, I can only hurry up and handle some things. If you disturb you in the New Year, I will apologize here."

"Master Liu, what you are causing trouble..." Everyone pointed at Liu Huaide as if he was the culprit.

"I, I just said casually, General Chen, don't take it seriously." Liu Huaide seemed to be smiling.

Of course, they were all clever people and did not ask why Chen Wanrong left or why he left. Without asking, they could also imagine that they were both happy for Chen Wanrong and that they were honored to have the military supervisor because Chen Wanrong was the head of the military weapon supervisor.

"My friend, tell us quickly." Ye Tianheng was a little anxious.

Sima Chengzhen took over the conversation and said, "Master Ye, my friend has been talking for a long time, you have to let him rest."

"Master, you are not interested enough. You will get the moon first when you get close to the water." Everyone's accusations flew over.

Sima Chengzhen smiled and said, "It's better to come sooner than to come by. I came with my disciples. I have such an opportunity. This is the merit of my cultivation and accumulation of good deeds."

"Merit?" Everyone burst into laughter.

Whoever says that monks must act like a slutty person? Isn’t it good to tell jokes?

Sima Chengzhen continued: "There is a compiled record here. You can pass it on. If you have any questions, please ask your friend to explain it."

Chen Wanrong was indeed a little dry-mouthed. This was a good solution. Before he could speak, he heard Ye Tianheng object and said, "Passing? Who reads first and who reads later? I see, why not find someone to read. I see, just read it. My friend's throat is dry, so why don't the Taoist priest do it too? The Taoist priest has heard it, and he will explain it to us while reading it."

"I agree!" Everyone applauded, and the matter fell on Sima Chengzhen's shoulders.

Sima Chengzhen did not refuse, and picked up Zheng Qing's record and started reading it. While reciting it, he explained it to everyone. Sima Chengzhen had a good memory and amazing understanding. His explanation was almost the same as Chen Wanrong's explanation, and everyone was fascinated by it.

Until I finished reading, there were only a few things that Sima Chengzhen was not very familiar with, which had to be explained by Chen Wanrong.

After reading, there was silence in the room. Ye Tianheng and the others were savoring and thinking. After a while, everyone came back and Liang Lingzan said, "After listening to the Taoist priest's explanation, I think this is a grand plan and there is a lot of equipment to do. This requires brainstorming. Let's discuss it together."

He really told him the key points. Starting with sulfuric acid, a systematic chemical industry has already appeared in front of them. There are too many equipments to do. If it were in modern society, all equipment could be bought with money. However, in the Tang Dynasty, these equipment could only be made and could only brainstorm.

"Master Liang said very well!" Chen Wanrong agreed with his words and said, "Everyone, this matter is of great significance. It can be said that the Tang Dynasty will be very different from the past from now on. We will focus our minds and work together to make sulfuric acid first."

Once sulfuric acid is made, medicine, agriculture, military industry, and daily life will benefit from it. It is not bragging to say that the Tang Dynasty was very different, but a promising and beautiful prospect.

Everyone dared not doubt this at all. They nodded and began to talk about their own ideas when they heard this. They discussed the problem and argued, and sometimes they were red in their faces. However, this was an academic debate, not a dispute of will, nor a dispute of interests. No one cared about it, and it was for nothing to worry about it.

For a moment, there was a buzzing sound in the living room, and the fight was endless.

Time passed, and when it was dark, everyone was fighting hard, and no one cared about time. On that day, no one had the idea of ​​going home, so they rested at Chen Wanrong's mansion. The next morning, everyone rushed to the living room, and then discussed yesterday's ideas. After resting for the night, the ideas became clearer, the signs of consistency became more obvious, and the differences were significantly reduced.

Another day passed, and everyone was still resting at Chen Wanrong's mansion. On the third day, they continued to discuss and discussed until dusk. Most of the problems had been solved. Even the details were consistent, and even the drawings of the workshop were drawn.

Chen Wanrong can only say that he has some understanding of machinery, let alone proficient. Without their help, Chen Wanrong would not have been able to obtain the chemical equipment he needed. He was complacent of his chemical knowledge and could only rot in his stomach and could not have been put into production.

Looking at the drawings, Chen Wanrong was very satisfied. "Countless scientific facts have proved that if a good science and technology wants to be transformed into a product, it requires outstanding mechanics to complement it. If there is no mechanic to manufacture suitable equipment, then all the technologies are talked about. It is so lucky that I could meet such a group of outstanding talents in the Tang Dynasty! Without their help, I would be just an alchemist with chemical knowledge at most, and it would not be possible for chemical engineering to take root in the Tang Dynasty."

In addition to feeling, he thought: "Sulphuric acid is known as the mother of industry. Once sulfuric acid is made, its huge uses will also be revealed. Agriculture, medicine, military technology, daily life, all aspects will be related to sulfuric acid. The chemical industry that emerged will sprout like mushrooms after a rain. It can be said that once this matter is done well, chemical engineering has taken root in the Tang Dynasty! I am not in vain to travel through time!"

Chen Wanrong was right. Sulfuric acid was known as the mother of industry. This title was not for nothing, but because it was used too widely. As long as sulfuric acid appeared in the Tang Dynasty, the subsequent emergence of the industry would be natural.

Due to the emergence of sulfuric acid, a series of chemical engineering studies are just around the corner, and chemical engineering has successfully taken root in the Tang Dynasty! This is exactly the direction of Chen Wanrong's efforts, and Chen Wanrong couldn't help but feel relieved.

Just as Chen Wanrong was feeling emotion, Niu Shangxin quickly stepped in and said in panic: "Boss, the emperor is here!"

It is a supreme honor for the emperor to arrive, let alone the glory in the New Year. Is it necessary to say that glory? Niu Shangxin's voice was too high and a little sharp.

"The Emperor is here?" Not only Chen Wanrong was surprised, but even Ye Tianheng and the others could not imagine it and were surprised: "Hurry up, go and welcome him!" Everyone rushed out of the living room without waiting for Chen Wanrong to speak.

Li Longji was strode, with Princess Jinxian and Princess Yuzhen, and Gao Lishi following him. Today, Li Longji did not wear a crown, did not wear a royal robe, and dressed in casual clothes, which seemed very relaxed.

"See the Emperor!" Everyone saluted.

Li Longji waved his right hand and said, "Forgive, forgive! I walked around today, and as I walked, I came here."

This is a joke, and everyone laughed loudly. Li Longji looked at Chen Wanrong and said, "I heard that you are crowded with people, and you are here to join in the fun. Where are you? There are only a few people?"

Chen Wanrong smiled and said, "Emperor, how can I get a lot of people in my house?"

"No? I wronged you?" Li Longji pointed to Ye Tianheng and said, "As soon as Master Ye and the others arrived, they would not return for a few days. Do you still want them to celebrate the New Year? Tell me, what are you discussing? If it is said well, I can not pursue it. If it is said poorly, you will also know the consequences."
