"That's all for the coal and coke chemical industry, let me talk about the situation of the seawater chemical industry, I am engaged in the electrolysis work in the lead and zinc mine, Mr. Zhao said that I am familiar with the business, so let me explain.

First of all, we have obtained two sets of micro seawater desalination equipment, one is electrodialysis method, and the other is multi-stage flash evaporation method, which belongs to the special equipment for seawater desalination, which belongs to the more advanced category in technology, of course, the technology is also very mature. ”

"Brother Gui!"

I heard high school students here raise their hands to ask questions.

"Huh? Go ahead. ”

"We don't seem to have a shortage of fresh water in this archipelago, so why does Anna give us desalination equipment?"

"That's a good question! Please sit down, I didn't understand it at first, but after reading the equipment list, I understood......"

Gui Xianning waved his hand to sit down, cleared his throat, and continued:

"The key here is the by-product of desalination – concentrated seawater!

According to the analysis of the equipment that Anna gave us, we can further process the concentrated seawater, in addition to producing extremely high-quality edible salt, we can also obtain seawater chemicals that are very important to us, such as magnesium, bromine, iodine, potassium and so on.

I won't say much about the specific technical details, you don't have to worry about the process, these are mature processes, I was originally worried that there are a series of technical difficulties, such as the preparation of filter sand, enrichment agent and catalyst, etc., but now it seems to be too much. Because according to our original understanding, even in this old world, the filtration media, enrichment agents and catalysts of seawater chemical industry are a major technical problem, let alone travel back to that era three hundred years ago.

But! Everybody! Anna gave us a lot of technical information, hehe, a lot of technical secrets that are not available in this world!

Now I am happy to tell you that many rare earth catalysts, enrichment agents and filter materials that are difficult to prepare in this world can be extracted from many marine organisms and plants!

For example, kelp anemone shells or something, the most advanced of which is the biomolecular filter, which is extremely cutting-edge technology in the contemporary industrial field, I dare to say that human science and technology are still ignorant of this field!

For example, if a certain seaweed is propagated, processed into a powder, and then mixed with animal fat and processed in some way, it can be made into a filter for a special purpose.

For example, by refining the oil of a certain fish in the sea, and then combining it with a certain plant on land, it is possible to make enrichment agents and catalysts with unexpected effects, and so on.

Suffice it to say, as long as you know, then these methods are very straightforward and simple, but obviously this is by no means the technology of our time, it is the technology of the future that Anna brings to us!

Probably Anna thinks that these technologies belong to the category of harmlessness of humans and animals, so he gave us the process flow and various process data and parameters. Therefore, in terms of seawater chemical industry, we have the most advanced technology and process in the world.

The equipment for the seawater chemical industry is universal, as its key enrichment agents, catalysts and molecular filter technologies are far ahead of their time, and as a result, our seawater chemical industry can do almost anything in the production of chemical products!

Let's put it this way, open the periodic table, as long as there are elements in the seawater, we can basically produce them through seawater chemical means! Cheers everyone! ”

"Too professional to understand ......"

"Cheer what?"

"Xiao Guizi, it's a little difficult for you to get outsiders to cheer you in your field of expertise."

Everyone responded.

"Well, all you need to know is that we don't have a golden finger, but a golden thigh thicker than an elephant's leg. Anyway, we have crossed over, and we can't hear the complaints of a group of reasonable parties who travel through novels......"

"Oh? Is there a golden thigh hug? That's a lot of cheering! ”

"So, I already knew that Anna was a cold-faced and hot-hearted fellow."

"Applause!"

Seeing that everyone's reaction was really enthusiastic, Gui Xianning was very happy, so he went on to introduce:

"Of course, not all chemical products are suitable for seawater chemical preparation in terms of production efficiency and cost, but if there is demand from various industrial sectors, we can make it!

Awesome, guys! Note that this is a technical secret given to us by Anna, and we are going to take it to the new world, and it is a great gift from Anna to us. Obviously, this is a great benefit to our chemical industry, and it also means that the development of our various industrial industries will also take a lot of detours! Here, we owe our heartfelt and recurrent thanks to Engineer Anna......"

"Applause!"

Bang Bang Bang ......

Finally, there was a rare round of applause in the restaurant, and everyone's mood gradually rose.

"Everyone! Be quiet! There is one more important thing to explain.

Although Anna didn't say it explicitly, we certainly wouldn't leak this technology to the current world, and we didn't want to leave it to this fucking old world. What's more, it won't be long before this era will become a mutilated ancient human relic!

Of course, if you are interested in learning about these technologies, you can get them, because they are all our ......

Thankfully, we have a chance to leave this dirty old world, so to hell with it! Alright, that's the end of my introduction! ”

Gui Xianning finished speaking concisely, bowed slightly to everyone, and sat back in his seat.

Bang bang bang, there was a rare round of applause in the cafeteria, and the sound of slapping the table and stomping feet, especially the most noisy from the group of high school students.

"Well said!"

"To hell with this filthy old world!"

"To hell with it!"

"There is no hopelessness in this world!"

"Eat jujube pills!"

By the end, almost everyone in the restaurant shouted in unison, and people rhythmically slapped the tables together, and the sudden sound made the glass windows of the restaurant tremble slightly......

No matter how excited the noise is, there is a time when it calms down, and Sun Lao waited until everyone felt a pain in their hands, and stood up in time and said to everyone:

"Everyone! Everybody! Let's continue to let Mr. Zhao explain the chemical industry well, okay? ”

"Let's talk, let's listen!"

Someone in the crowd responded.

"Then I'll continue."

Zhao Xihe stood up again, looked at the few pieces of paper in his hand and continued to explain:

"Oh, now to reply to a question, this is what someone asked me just now, saying that edible salt is a bulk trade commodity in the new world, and the quality of our products should be the first in the world, so why not take this product as the first batch of export commodities to be developed?

In fact, we have discussed this with many people, and Nicole listened carefully to our advice at the beginning, but she came to the conclusion that it was not worth it, at least initially.

Although she didn't give a reason, we later understood what Nicole meant, which was probably mainly considered from two aspects: cost and market access.

Although there is no problem with the quality competitiveness of our salt, there is a problem of cost performance. Although the total market value of salt is high, the unit price is far less than that of glass and sugar, and the market capacity of salt is also related to population.

However, in the 17th century, almost all densely populated salt markets were monopolized by the government under the control of the government, and if you wanted to enter it, you had to deal with the government.

To be honest, our group of people is actually very unsuitable for dealing with the government, especially the government of 300 years ago that belongs to corruption, ignorance and inefficiency in our eyes.

But whether it is smuggling or using artillery to open other people's borders, this is not something we can do in the early days. In order not to ask for trouble, the salt project was not selected.

The second is the issue of our production capacity.

Because the unit price of this thing is not very high, so the amount is less than how much money can be earned, and the large amount consumes our precious resources, taking the Pride as an example, the value of transporting a shipload of sugar overseas is obviously much higher than transporting a shipload of salt. If we produce salt in large quantities, it may even affect our industrial development progress, because seawater chemical industry is a very electricity-intensive process, and in the early stage of crossing, it is likely that we will not be able to carry out this industrial project because of the lack of electricity. In the end, the project was rejected by us. ”
