The technician left at the estuary base by the chemical company was named Hou Zhiben.

In that side of the world, he has worked in many large, medium and small chemical plants, and has left his dreams in all parts of the world, but the result is ...... I won't say anything.

He greatly admired his chemist, Mr. Hou Debang, and highly respected Hou's alkali method. He believes that this is the best way to make alkali in the world, and it is the swan song of a certain nation in the chemical industry!

If it weren't for the fact that the chemist Mr. Hou Debang had not been forced to go to Sichuan to set up an alkali factory, if it weren't for the fact that Sichuan's well salt was too expensive and too costly, God knows if the chemist Mr. Hou Debang still had the urge to change Solvay's alkali production method.

Forgive the boy for being bold, and all of them are just assumptions, and they are not known.

Technician Hou Zhiben was supposed to go to Budai Town, but chemical talents are also needed for papermaking and leather processing on the Hekou base.

And most importantly, he resented Budai Town's alkali production method in his heart, although he could understand why. But emotionally it's just unacceptable. Personality, you know?

They even started the Lubrand-style alkali making method!

Oh my God, do you know how wasteful that is? As soon as you compare it, you will know how great the Hou's alkali method is.

The Lubran alkali production method is divided into three steps, first reacting sodium chloride with sulfuric acid to generate sodium sulfate, then reducing sodium sulfate with coke to obtain sodium sulfide, and finally using the reaction of sodium sulfide and limestone to produce sodium carbonate and calcium sulfide.

This method is difficult to produce continuously, step by step to take out and input, and need sulfuric acid as raw materials, the equipment is corroded strictly, the product quality is not pure, the utilization of raw materials is not sufficient, and the cost is very high.

This is simply an insult to the traverser!

It was patented in 1791 by the French doctor Roubrand, but now it is even used by the chemical talents of the traversers! Shame on you.

However, resentment is resentment, but he also knows very well in his heart that this is the most appropriate way under the current conditions.

This qiē is really a contradiction.

Sulfuric acid is easy to do, and Taiwan originally produces natural sulfur, iron sulfate, and copper sulfate. Besides, a lot of them were seized this time. The equipment of the sulfuric acid plant brought by the traversers is beginning to be deployed in Budai Town, and the cement of the Hongxing Cement Plant and the red bricks and red tiles of the Hekou base have accelerated the construction of the plant.

Limestone, produced in Budai Town itself.

The salt works in Budai Town have long been completed, and of course, the output is not comparable to the salt works in the world. But it's enough for the traversers to use now. I'll talk about that later.

Coke can be replaced by high-temperature machine-made carbon, which is equal in terms of carbon content, and the ash content of machine-made carbon is also low.

All the reaction conditions can be solved with a high temperature, so what is the use of this technology?

Sodium sulfate itself is a good thing, in industry it can be used in papermaking, glass, printing and dyeing, tanning, synthetic fibers.

Except for the last one, which one do you say the traversers don't want?

In addition, calcium sulfide, a by-product of the Lubrand's alkali production process, is also very useful, it can be used as an additive for tanning and depilatory, pesticide fungicides, light materials, lubricants, and veterinary drugs.

Except for the light materials that can't be used for the time being, which of the rest of the traversers don't want it?

However, from the products they need, we can see the idea of the traversers.

And when sodium chloride reacts with sulfuric acid, the hydrogen chloride produced is also a good thing, right?

When sodium sulfate is reduced with coke to obtain sodium sulfide, the carbon monoxide produced is also a good thing, right?

How to seal, how to improve the purity is another matter. The traversers had already prepared.

Besides, in this time and space, is there a high requirement for purity? If the equipment is all corroded, then the traverser will go another way.

Up to now, we can fully see that the traversers have been determined to take an evil road of comprehensive utilization and comprehensive output from the beginning, and will not take the correct path of refinement, refinement and specialization for the time being.

The countless technical imaginations of the technical otaku were shattered by these middle-aged uncles who have been working in the chemical industry for a long time.

Then this so-called soda plant will definitely be built into four dislikes.

When the decision of the Hantang Group Chemical Company came down, Wang Qiang, the manager of the chemical company, was not very happy when he saw the technician Hou Zhiben, he patted the technician Hou Zhiben on the shoulder and said, "Brother, let's get out of the actual situation, and wait for you to get the ammonia production out."

We have the equipment, but what about the coal? If we use charcoal to make ammonia, then all our charcoal output will not be enough.

Technician Hou Zhiben is a friend made by Wang Qiang, the manager of the chemical company, after the crossing, the manager of the chemical company Wang Qiang shows that he has a rare kindness in the world, as if the experience of wandering around did not harden his heart, but sharpened it softer and brighter, with only a small shortcoming, and his temperament was a little impatient.

Of course, this is nothing for us young people. We are really young people now.

Technician Hou Zhiben knew that the chemical company also brought some liquid ammonia, but that was to be used for 6 cold storage, if it was used to produce alkali, then whether it was the ammonia-alkali method of the Belgian Solvay, or the joint alkali production method of the best chemist Mr. Hou Debang, it was far from enough.

Therefore, the Lubrand-style alkali production method is now the most practical, and of course the best.

Technician Hou Zhiben sighed helplessly, this is the case.

Wang Qiang, the manager of the chemical company, first arranged for him to go to the Hekou base, afraid that he would be angry.

Technician Hou Zhiben clenched his fist and said as if he had an oath: "Don't worry, we will definitely be able to produce ammonia." ”

"Of course, with it, we can really be said to be invincible in the world."

The soda plant is built at the downwind of Budai Town, far away from the salt farm, far from the sulfuric acid plant under construction, and even far away from the lime plant. Because this method has not been tested in practice, the traversers are a little afraid.

Chemical industry is never a joke.

There's no way, if you really use the primitive and backward Lubran alkali method, judging from the amount of time traversers put in at a time, there is no way to stay around.

A large amount of hydrochloric acid fog can kill people.

At the end of the 18th century, the alkali produced by the Europeans only had a lot of output, which was not enough for the traversers to see, so they Europeans used the method of open-air production, but the traversers could not.

The low-pressure reactor is made of ordinary carbon steel, and as long as the temperature is only 425C, it has nothing to do at all. In fact, the temperature required for the first step of the reaction between sodium chloride and sulfuric acid is far from reaching such a high level.

If the temperature exceeds 425C, it is really bad, and the carbon in ordinary carbon steel will be graphitized, thereby changing the mechanical properties and corrosion resistance of the material.

However, those who have crossed the 425c can choose from heat-resistant steel and low-alloy steel that are resistant to high temperatures, and their pockets are quite deep.

Any equipment can be suppressed, but Li Ziqiang didn't dare to move Sun De's reactor and high-temperature and high-pressure resistant equipment.

The second step is that the charcoal reduces sodium sulfate reaction, which is simpler, and calcined at high temperature.

The clay refractory bricks at the estuary base are fully applicable and have been tested by the Red Star Cement Plant. The gas collector on the reactor kiln body is a modern equipment that can send the reacted carbon monoxide back to the kiln body. Energy conservation and emission reduction start from the traverser, in fact, it is not very difficult.

The third step is that the reaction between sodium sulfide and limestone is easier, and it is calcined at high temperature.

Finally, it is separated by water dissolution. After the solution is concentrated, sodium carbonate crystallizes and precipitates, while calcium sulfide is not easily soluble in water and naturally precipitates.

As for the hydrogen chloride generated during the first step of the reaction, the traversers had already arranged it, and a drenching scrubber was done. They fill the scrubber with charcoal. In the tower, the hydrogen chloride gas rising from the bottom of the tower is absorbed by the falling water to produce hydrochloric acid.

Of course, they have a backhand, and in the next stage, they mix this hydrogen chloride gas with preheated air to produce chlorine gas through the oxides of guò copper and manganese. Then let it pass guò lime water, you can make the disinfectant powder that you always need. and possibly potassium chlorate...... However, in the current situation, chlorine is still easier to produce by electrolysis of brine.

Sample, such a broken thing has also been integrated into the idea of joint chemical production.

The people in the chemical company are not at all worried about the sulfuric acid plant and the alkali plant that they have designed. But people in other industries are really scared. Can these non-earthy, non-foreign devices work?

If it weren't for the safety of people, the other traversers would have wanted to build these sulfuric acid plants and soda plants on one isolated island.

Although the people of the chemical company patted their chests to ensure that Yiqiē was safe and sound, safer than the PX project, and would never cause a group incident, they did not touch the interests of the local tyrants.

But the other traversers are still afraid, who can understand what you say.

Their little eyes came out again.

Let's take a look back at the opening of Budai Town.

The place name of Budai Town originates from the sand spit that surrounds the outer and dwells deep in the lagoon, and is named after the shape of a cloth bag. In the past, it was called "Bu Darui" and was falsely rumored to be "Budai Mouth", and it was also called "Daijiang" by the Sao people and inkmen, and it was also the local gentry who took the cloth bag of the Seven Lucky Gods during the Japanese occupation and the Shang Ya number, and continued to use it in the name of the cloth bag until before the crossing.

After the crossing, the traversers still use the original name for fear of making a mistake.

Before the crossing, Budai Town was located in the southwest coast of Chiayi County, Taiwan, adjacent to Dongshi Township in the north, Puzi City in the northeast, Yizhu Township in the southeast, Taiwan Strait in the west, and Beimen Township in Tainan County across Bazhang River in the south.

Like the city of Relanza, it is located on the Jianan Plain, the terrain is low and flat, and it is formed by the alluvial accumulation of Bazhang Creek many times, and the reason for its formation is the same as that of the area where the Hongxing Industrial Zone is located.

It's just that it's a little farther away, about fifty kilometers in a straight line from the city of Geranza, but there is still a road to get there, although it is not easy to walk, but at least there is.

There's a reason why the traversers chose to open another base here.

Before the crossing, it was the largest salt pan in Taiwan Province, off the southwest coast of Taiwan Island. The beach is widespread, the terrain is gently sloping, and the river does not inject much fresh water.

The monsoon here is strong, especially in the winter half of the year, dry and rainless, the sunshine is long, the temperature is high, the steaming is fast, the salt content of the sea water is high, the concentration of Polmy is high, the salt content is 35 parts per thousand. It is known as the "southeast salt warehouse".

After the crossing, the traversers went there to check it out, but fortunately there was not much change.

It's just strange why the salt makers there don't use the drying of salt, but use the labor-intensive and time-consuming technique of boiling salt. waited to read the information, only to realize that it was necessary for Zheng Chenggong to come here for twelve years before he brought the salt-drying technology.

However, as the traversers went deep into the Budai Town area and learned about it carefully, it turned out that the salt boilers here did not know how to dry salt.

The tools for boiling salt only need an iron pot, and you can take it and go. If the method of drying salt is adopted, the initial investment is large, and I don't know how to treat the Dutch red hair, it will be a closed door and a dog, then the early investment in reclaiming the salt pans will be completely lost.

Damn, it's really a qiē that can be explained!

The Dutch East India Company, just one more argument for colonial plunder. In fact, in the hearts of the traversers, they hoped that the Dutch East India Company would open up 10,000 acres of salt pans for them to receive.

(A Taiwanese friend argued with me that Zheng Chenggong would only boil salt before he took back Taiwan, and he thought it was due to technical limitations, at least according to many public sources.) But the kid thinks that the strait of more than 100 kilometers cannot achieve the effect of shielding technology, unless in that world, what kind of mystery is salt drying? So I checked the relevant information and got this conclusion in this article, I don't know which party you recognize? ）

There are only a few salt boilers in Budai Town, only about 100 people, all of whom come from the coastal areas of Fujian to cook salt. Especially the people of Xiamen. It is relatively close to Xiamen and has convenient transportation.

There is also a port here, which is not big and relatively dilapidated. The traversers don't look at it, so they haven't sent someone to receive it, it's not worth it, and they think it can be passed on.

The traversers are also afraid of accidents, so don't scare them away. Before they arrived in Budai Town, they arranged for Wu Hualong to lead his brother there first to promote the policies of the Han and Tang companies.
