    "Wanrong, is everything you said true?" Chen Laoshi, who was born as a farmer and was most concerned about fertilizers, was the first to react and asked: "Wanrong, what you said sounded better than what you sang. You can't be lying.  Bar?"

    This kind of thing was unheard of and unheard of. It was really difficult for him to believe it was true all at once.

    Phosphate fertilizer is one of the modern chemical fertilizers and has played an extremely important role since its emergence.  Without phosphorus, would modern agriculture be so productive?

    Chen Wanrong affirmed: "Dad, how can I tell such a big deal?"

    "Think about it! If you really have such a fat position, the farmers will wake up laughing when they fall asleep!" Chen Laoshi's eyes were very bright, staring at Chen Wanrong, urging: "Wanrong, since there is such a good thing,  Hurry up and make the fertilizer. Dad will go to the whole piece of land and try it. If it is really useful, tell the emperor that it will be promoted in the Tang Dynasty and all the people will use it. With the fertilizer,  The common people will have enough to eat.¡±

    No one thought that Chen Laoshi, who was usually quick-tongued, would have such a broad mind, and everyone was stunned.  Seeing everyone looking at him, Chen Laoshi felt a little embarrassed and said sarcastically: "Wanrong, did dad say something wrong?"

    "Dad, you are right, you said it very well!" Chen Wanrong praised, then changed the subject and said: "Although this fat is good, it takes some time to make it. First, you have to make the sulfuric acid. Without sulfuric acid, this  That¡¯s all for being fat.¡±

    "Then tell the Taoist priest how to make this sulfuric acid? We can't afford to delay such a big thing, the sooner the better!" Chen Laoshi urged.

    Mrs. Chen Wang rarely echoed his statement: "Yes! Wanrong, my mother is a farmer, and I know how important fertility is to farmers. Just tell me quickly, we are listening."

    They don¡¯t understand chemistry, so it sounds like they are in vain, they are just joining in the fun.  Chen Wanrong responded: "Taoist Master, there are many ways to make sulfuric acid. We can only use the method that suits us best at the moment."

    The best is not as good as the most applicable. There is nothing we can do about it. The Tang Dynasty had that condition.

    Sima Chengzhen nodded and said, "My little friend, please speak. I'll listen."

    Chen Wanrong talked about the uses of sulfuric acid for a long time. Every condition has wonderful uses that people can't imagine. The relationship between sulfuric acid is so important. Sima Chengzhen was particularly excited and his ears stood up.

    "There are two raw materials for making sulfuric acid, one is sulfur and the other is saltpeter ore. If there is no sulfur, you can also use pyrite." Chen Wanrong began to explain the manufacturing method of sulfuric acid: "You need to make an incinerator to combine sulfur and  The saltpeter ores are put together and burned. The generated gas enters the denitrification tower to remove nitrogen oxides. The treated gas enters the acid-forming tower, and then passes through the nitrification tower to obtain sulfuric acid."

    Chen Wanrong¡¯s production method is different from the lead chamber method and the contact method.  The problem with the lead chamber method is its low efficiency and low concentration of sulfuric acid.  Furthermore, lead is too expensive and the cost is high.  It is precisely because of this that the lead chamber method was replaced by the tower method.

    The lead chamber method is the oldest sulfuric acid production method and has existed for more than a hundred years.  It is called the lead chamber method because the main equipment for producing sulfuric acid is a hollow square lead chamber, hence the name.  The principle is the same as the tower method, which uses nitrogen oxides to oxidize sulfur dioxide to generate sulfuric acid.

    The sulfur dioxide obtained after incineration has a temperature of about three to five hundred degrees. After the denitrification tower removes nitrogen oxides, the main products extracted are sulfur dioxide, nitrogen oxides, oxygen and water vapor.  What is obtained from sulfur dioxide is sulfurous acid, not sulfuric acid, so it needs to be further oxidized to obtain sulfur trioxide. This step is completed in the lead chamber.

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

    As a result, more lead chambers are needed and the cost becomes higher.  At the same time, the concentration of sulfuric acid produced by this method was low and could not meet the needs of industry, which forced improvements, which led to the advent of the tower method.

    The so-called tower method is to replace the lead chamber with a packed tower filled with fillers.  The advantages of this method are that, first, it no longer uses a large amount of lead and reduces costs.  The second is the use of fillers, which have a "cutting" effect and improve efficiency.  Third, the sulfuric acid concentration obtained by this method is higher.

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

    The concentration of sulfuric acid 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 a catalyst.  Under the current conditions, we can only think about creating a catalyst?

    Looking at the drawings, Chen Wanrong was very satisfied. "Countless scientific facts have proved that if a good science and technology is to be transformed into products, it needs outstanding mechanics to complement it. If there are no mechanics to create suitable equipment, then  All technologies are nonsense. I am so lucky to have met such a group of outstanding talents in the Tang Dynasty! Without their help, I would at best be an alchemist with chemical knowledge, and it would be impossible for chemical industry to take root in the Tang Dynasty.  "

    While sighing, he thought: "Sulfuric acid is known as the mother of industry. Once sulfuric acid is made, its huge uses will become apparent. Agriculture, medicine, military technology, daily life, all aspects will be related to sulfuric acid. Then.  And the chemical industry will spring up like mushrooms after a rain. It can be said that once this is done, the chemical industry will have taken root in the Tang Dynasty! It¡¯s not like I¡¯ve traveled through time in vain!¡±

    Chen Wanrong is right. Sulfuric acid is known as the mother of industry. This title is not for nothing. It is because it has so many uses.  As long as sulfuric acid appeared in the Tang Dynasty, the emergence of subsequent industries was a matter of course.

    Because of the emergence of sulfuric acid, a series of chemical engineering studies were just around the corner, and chemical industry successfully took root in the Tang Dynasty!  This is exactly what Chen Wanrong is working towards, and Chen Wanrong couldn't help but feel relieved.

    Just when Chen Wanrong was sighing with emotion, Niu Shangxin walked in quickly and said anxiously: "My boss, the emperor is here!"

    It is a great honor for the emperor to come here, not to mention it is in the New Year, needless to say that honor?  Niu Shangxin's voice was too high-pitched and a little shrill.

    "The emperor is here?" Not only Chen Wanrong was surprised, but even Ye Tianheng and the others were surprised and said, "Quick, go greet him!" Everyone rushed out of the living room without waiting for Chen Wanrong to speak.

    I saw Li Longji striding over, Princess Jinxian, Princess Yuzhen, and Gao Lishi following him.  Today, Li Longji did not wear a crown or imperial robe. He was dressed in casual clothes and looked very relaxed.

    "See your Majesty!" Everyone saluted.

    Li Longji waved his right hand and said: "No need, no need! I walked around and walked around today and ended up here."

    This was a joke, and everyone burst out laughing.  Li Longji looked at Chen Wanrong and said, "I heard that your place is bustling with people welcoming people and sending people there, so I came here to join in the fun. Where are the people here? Just these few?"

    Chen Wanrong smiled and said: "Your Majesty, where is the bustling crowd in this mansion?"

    "No? Have I wronged you?" Li Longji pointed at Ye Tianheng and said: "As soon as Master Ye and the others come to your place, they don't come back for a few days. Do you still want them to celebrate the New Year? Tell me, what are you discussing? If you say it well  , I don¡¯t have to pursue it. If you don¡¯t say it well, you will know the consequences."

    Although he was saying threatening words, he had a smile on his face, and Ye Tianheng and the others couldn't help but laugh.  (To be continued.
