The main course of dinner on this day was the local specialty, lobster.

Originally, according to the local way of eating, it is usually smeared with a little salt and roasted.

But apparently, the catering service provider that Nicole found for the "tourists" in the Red Mansion has more service qualifications, and has a little understanding of the foodie attributes of these tour groups from an ancient country, so she specially equipped these grilled lobsters with various spicy sauces and drinks, and the amount is very sufficient.

So, tonight, everyone had a good dinner.

When the big lobsters on everyone's plate were almost only piles of lobster whiskers and lobster shells, Sun Lao stood up and announced that the aid list discussion was now open, and the speaker was Mr. Zhao Xihe, and the topic was about the basic raw materials that launched the first industrial revolution in human history after we crossed over: three acids and two alkalis.

After a round of warm applause, Mr. Zhao held a toothpick in his hand, picked between his teeth, stood up from his chair, glanced at a stack of documents in his other hand and said:

"Guys, because this topic has been dragging on for too long, so I'm going to get straight to the point here. Let's talk about sulfuric acid first, Anna gave us two sets of traditional miniature boiling furnace process equipment, well, yes, there are two sets in total.

I won't say much about the specific content that is too specialized, the principle is nothing more than roasting sulfur or pyrite, and then collecting the gas and mixing it with oxygen to turn it into sulfur trioxide, and then passing it into distilled water to become dilute sulfuric acid, and then evaporating the water as needed, it becomes dilute or concentrated sulfuric acid.

Well, these two sets of equipment are good, but there is low-grade pyrite on our island, although the equipment is miniature, but in the early stage of development, both equipment and raw materials are enough.

The importance of sulfuric acid Everyone here should know, from medicine to ** sulfuric acid is indispensable, is the basic raw material of our chemical industry.

Although the yield of the micro boiling furnace is limited, we can replicate this set of equipment in the same way, and if two sets are not enough, three sets will be used! Three sets are not enough, four sets! Until the yield is enough to meet all our needs. Of course, if we get a higher quality raw material than low-grade pyrite, such as sulfur, then the yield will be higher and the quality will be more guaranteed.

Here, on behalf of the members of the chemical group, I would like to express my attitude: please rest assured, because the principle of this set of equipment is simple, the volume is not large, to be honest in our eyes it is like a big toy, it is relatively easy to operate, and the work is not too tiring, the key is that it is not very difficult for us to copy in the future.

In particular, if we can obtain better quality sulfur in the future, then we are sure that in the near future, the production and quality of sulfuric acid will fully meet our needs. Well, that's all for the sulfuric acid issue.

Let's talk about the production of hydrochloric acid, Anna gave us the electrolytic hydrochloric acid production line, although this production line is a large power consumer, but the process equipment is very neat and advanced. Of course, the facilities including electrolyzers, buffer tanks, synthesis furnaces, absorption towers, exhaust towers, and storage tanks are miniaturized, eh...... In addition to the larger storage tank, all the equipment is the same as the sulfuric acid production line, which is the size of a large toy.

What needs to be explained here is that electrolysis is the mainstream method of hydrochloric acid production today, with high efficiency and relatively easy preparation of raw materials, but the disadvantage is that it is more electricity-intensive. In addition, the production of electrodes requires us to carry out technical research, and we will have internal professional discussions on this later, so I will not say much about it here.

However, because it consumes too much electricity, we estimate that we will need to build one or two run-of-river power stations specifically for this production line to provide electricity.

Although it costs electricity, the benefits of this process are also obvious, the by-product of the electrolysis method is sodium hydroxide, commonly known as caustic soda, which is one of the two bases in the three acids and two alkalis, but the yield may not be stable, and we estimate that the limestone causticization method will eventually need to be used to make up for the lack of caustic soda production.

Okay, now let's talk about nitric acid, everyone knows this thing, what nitroglycerin, silver mirror reaction or something, we all know what this thing means, it is known as a weapon for traveling, and it definitely belongs to the goldfinger type of thing in the crossing novel.

So in any sense, nitric acid is our first need, and when the time comes, we will engage in TNT smokeless or something, and nitric acid will be even more essential.

But the problem is that there is no saltpeter as a traditional raw material for industrial nitric acid production in this archipelago, although the toilet soil is a traditional method of making nitrate, but obviously the output is limited, and we do not have a lot of labor to go to the salt land to sweep the nitrate by hand, and the efficiency of doing that is very low, so unless there is a large number of cheap labor, that traditional method is basically unrealistic.

What to do? Those of you who have some chemical knowledge know that in addition to saltpeter, the raw material for making nitric acid also uses ammonia oxidation, but the process is more complicated, and it requires platinum rhodium metal catalysts.

Obviously, Anna didn't mean to give us these supplies, so Anna's engineer's solution was very different, and I was a little surprised: he actually gave us a set of arc production equipment!

Because from the perspective of craftsmanship and equipment, this is an antique-like existence, anyway, I have only seen this kind of craftsmanship in books.

Before I saw this set of equipment in the cave the day before yesterday, I never thought that I would see such a complete set of cultural relic-level industrial equipment in my lifetime!

How old is this thing? I guess you won't find it in any chemical plant in this world, and I think this set of equipment was acquired by Engineer Anna from a museum in the way of space-time replication, and the reason why this method was eliminated was that it was too power-intensive, and second, the conversion rate was very low.

Of course, the benefits are also obvious: the raw material almost does not need to be prepared, because its principle is to use a strong current to generate an arc, and after discharging in the air to produce nitrogen dioxide, due to the large proportion of this gas, it will sink to the bottom of the container, and be absorbed and synthesized into dilute nitric acid by the distilled water at the bottom, and then mixed with sulfuric acid and heated under pressure, it will produce concentrated nitric acid. Simple, right? The raw materials are air and distilled water! However, the seemingly simple process is not easy to achieve, and the main reason is that the power consumption is to the extent of cheating!

Therefore, we believe that it is necessary to build a small thermal power plant or hydropower station to supply power on a special line, otherwise, it is estimated that as soon as our electric arc furnace is turned on, the whole island will have to be blacked out......

Therefore, the production of nitric acid and hydrochloric acid requires the strong cooperation of the power sector.

In addition, whether it is electrolysis or arc method, the preparation of this electrode also needs to be cooperated by the metallurgical department. ”

Zhao Xihe said this, and looked at the Kangda Wang Zhanwu and Huali at the adjacent table.

"Mr. Zhao, I know this process, we have been involved in this knowledge in the university, but I remember that in addition to the power consumption is a bit amazing, the electrode consumption is large, and it is also necessary to manufacture high-temperature resistant materials, right? I'm really worried that we don't have this ability! ”

Wang Zhanwu thought about it and raised another key question.

As a result, this topic immediately sparked a big discussion among various professional groups.
