Chapter 251 Sequelae

The so-called Dao produces one, one produces two, and three produces all things.

This sentence is very reasonable.For example, when sulfuric acid is produced in chemical factories, nitric acid can be synthesized from sulfuric acid and saltpeter.

In addition, in the older way, hydrochloric acid is also prepared by reacting sulfuric acid and salt, but it was later changed to electrolytic salt preparation method.This is the so-called Three Lives and All Things.With the three kinds of acids, the chemical factory can gather all the dragons, and it can produce countless kinds of chemical products.

After the successful trial production of sulfuric acid, the original team first summed up their studies, and then began to prepare nitric acid.

The preparation of nitric acid is the simplest contact method: concentrated sulfuric acid + saltpeter.This method consumes a lot of acid, causes high pollution, and seriously corrodes equipment, so it has long been discontinued in later generations.

But the time-travelers have no choice.As mentioned earlier, the general ammonia synthesis technology in Steel City is not something that Hong Xu and his kittens can play with.

In fact, even with the existing equipment of the chemical plant, the workers cannot fully operate it.Right now, Hong Xu can only lead the same group of people to operate different complete sets of equipment in turn. They can't even do the simple process of producing sulfuric acid and nitric acid at the same time-they don't have enough mature technicians.

The "ancient method" to synthesize nitric acid is very simple in principle, but it also needs to go through many processes in practice.First of all, the saltpeter collected from the stinky saltpeter field contains a lot of impurities, and it is very troublesome to deal with various impurities in the saltpeter.In addition, when sulfuric acid and saltpeter meet in the reaction vessel, a little carelessness will produce violent splash and acid mist, which is likely to cause accidents. Qualified industrial nitric acid is not so easy to obtain.

After the first batch of sulfuric acid was reacted with saltpeter, the trial production of nitric acid was completed.Looking at the 2 tons of finished products being pushed into the warehouse by workers with trolleys, Hong Xu couldn't help shaking his head: Without it, there are too few raw materials.

The Nitian District, built in the north of Chikan New District, is being continuously expanded in units of 5 mu.However, this kind of expansion is very limited, and the production must be determined by "dung".

Although an open immigration operation with the permission of the government has been carried out on the other side of the sea, as of today, the total number of people under the control of the crossing forces has just exceeded 15 people-it takes time to transport and digest immigrants.

The feces and urine "produced" by these 15 people, together with some rotten fish and rotten shrimps, are all the raw materials for the nitration pond.And what is the final output of saltpeter?20 tons per month.

Of course, the saltpeter here does not refer to the semi-finished "nitter", but the finished saltpeter after purification, crystallization and purification.

Decomposing spoilage by nitrifying bacteria will go through many processes.Travelers has tried its best to provide the most comfortable conditions for Mr. Bacteria: such as a sunshade, such as a constant temperature of 25 degrees, such as a weak alkaline environment, such as oxygen-enriched, moist large-grained soil, and so on.

Even so, the output of saltpeter is still far behind the consumption.

You know, to fire a cannon, dozens of hundreds of grams of black powder are used. In addition, not only black powder, but also gunpowder factories and mines are waiting for nitric acid to make much-needed nitroglycerin.Also, the kiln base itself needs a lot of nitric acid to manufacture products and upgrade itself.

Finally, the excess saltpeter has to be used to fill the bottomless pit of fertilizer consumption. Both ammonia and urea are now scarce products. For the crossing forces that have cultivated more than 2 acres of Susukida, this output is purely a drop in the bucket.

In short, 20 tons of saltpeter per month is far from enough to satisfy a hungry primary industrial society.

The crossing people can only rely on the saltpeter brought in from time to time by the Dutch and Daming.This situation has undoubtedly caused a shortage of nitric acid. It is not an exaggeration to say that it is the most important chemical product at this stage.

After testing the production of nitric acid, Hong Xu immediately ordered the work to end.The next day, the original team tested the hydrochloric acid production line again.The preparation of hydrochloric acid is relatively easy. At least the output of the salt field this year has reached the kiloton level, so there will be no embarrassment of insufficient raw materials.

Electrolysis of saturated salt water will produce hydrogen and chlorine in addition to sodium hydroxide.In the reactor, pass hydrogen and chlorine gas to the burner made of quartz to ignite and burn to generate hydrogen chloride gas and emit a lot of heat.Hydrogen chloride gas is absorbed by water to become hydrochloric acid after cooling.

Due to the relatively powerful imported electrolyzers and reaction equipment, Hong Xu and the others have relatively easily completed the preparation of hydrochloric acid and caustic soda today.

The next step is the process of team proficiency.Hong Xu's requirements are not high: within half a month, everyone can start the three-acid production line at the same time.As for the other equipment, it can only be left idle for the time being. Let’s take it step by step. I don’t see if there are not enough raw materials now. Some products don’t have to be practiced if you want to practice.

To some extent, Hong Xu and the others took advantage of the loophole this time.Because according to everyone's tacit understanding all the time, all imported equipment is waiting for people, and there are very few cases of workers waiting for equipment like this in chemical plants.

And Hong Xu and the others took advantage of the strong professionalism of the chemical plant and secretly added some equipment, which led to the strange situation of the equipment and others.

This situation quickly caused dissatisfaction among some people, especially Zou Guoqing and Yao Zhesheng, the chief and deputy managers of the kiln area.

"I kind of understand why that bastard Hong Xu got mad on the day of the tour: it's called a guilty conscience, and I'm afraid people will see his flaws."

Yao Zhesheng held his arms, stood in the general machinery factory where the machines were roaring, looked at the long army of machine tools on both sides of the workshop, and said indignantly.

"This is the legendary old thief. Don't tell me, that guy acted quite like him, and he pretended to be the essence of a nerd." Zou Guoqing was not so angry, but commented on Hong Hong with a smile on his face. Sequential acting.

However, Yao Zhesheng, who has devoted his whole life to the great cause of time-traveling since the time-traveling, couldn't stand Hong Xu's behavior of "deceiving the organization".So when he found out that Zou Guoqing was in a good mood, he couldn't help turning his head and glaring at the old Zou, who had a protruding forehead: "Just let him slide over like this? How many urgently needed equipment are delayed like this!"

Zou Guoqing, who had already been in the cabinet and was in charge of the overall industrial planning of the crossing forces in the big office, showed a forgiving expression of "young man, you have been done too little by middlemen in your life", and then he said with a smile : "" They have already installed all the equipment, what can we do, dismantle it? "

Having said that, he patted Yao Zhesheng on the shoulder, and stopped the hot-blooded man's words: "Don't worry, justice will only be late, but it won't be absent. Pretend to be aggressive, the next time he cries!"
