The end of the Ming Dynasty swept the world

Chapter 557 Petroleum Expert Mito
Ding Yi smiled and nodded: "Thank you for your gift. In return, you can take away two thousand catties of candy in a while." Ding Yi didn't accept his gift in vain, and immediately returned the gift.

He has just been a senior officer for less than a year now, and he needs to establish his credit and reputation with merchants from all over the world, so as to attract more foreign merchant ships.

Awei was even happier. He thought for a while, and finally said: "I heard that the general is looking for someone who understands oil? Petroleum, the name is very interesting. Did you choose it, the general?"

"Yes, oil, 1000 taels of gold, I need an expert in this field." Ding Yi remained calm: "Mr. Awei, do you understand?"

"I only know a little bit, but I know an expert." Awei said: "He has been studying this since he was a child, and because he likes this, he was cast aside by his father, who thought he was not doing his job properly, and was abandoned by his family."

"Oh, where is he?" Ding Yi was overjoyed, but he didn't react much on the surface.

After all, he doesn't really believe that there will be relevant experts in this era.

He just had a fluke mentality and didn't ask the other party to be professional, as long as he could understand a little bit of principles, he could help them.

Awei didn't say anything at this time, and looked at Ding Yi.

Ding Yi smiled quickly: "Come here, take 1000 taels of gold."

"Wait." Awei shook his head: "General Ding is not afraid that I am a liar, so trust me?"

"You should be able to exchange sincerity in business. I believe Mr. Awei, you look like an honest businessman." Ding Yi smiled.

Avi felt embarrassed when he was said, of course he is not an honest businessman, honest businessmen can make money.

Only profiteers can survive in this world.

"I don't want gold." Avi said at this time.

"Oh, what do you want?" Ding Yi asked strangely.

"I don't need anything now. I want him to stay with the general. If you think he is really useful, general, I hope I can do something for him in the future."

Awei doesn't want gold, but a promise from Ding Yi.

"Is that so?" Ding Yi fell into deep thought.

He is a very trustworthy person. If he agrees to Awei, he is afraid that Awei will propose difficult things in the future.

These business people are really cunning, Ding Yi did not expect Awei to make such a request.

"Let me think about it." Ding Yi stood up and walked around.

There was a smile on Awei's face. If Ding Yi agreed on the spot without thinking about it, he would doubt whether Ding Yi would keep his promise in the future.

Now Ding Yi is deep in thought and consideration, which proves that this Ming man pays great attention to promises, so he thinks about it carefully.

Feeling that Ding Yi was a bit embarrassed, he thought for a while, and said: "Well, this promise does not have to be made by General Ding. In fact, I also feel that this promise is very difficult, but, I said but, if At that time, General Ding, if you have the ability, you can help to complete it, if it is difficult, then forget it."

Ding Yi immediately felt that this Awei was very interesting, and what he said made it easy for people to have a good impression of him.

Definitely a smart businessman.

"Okay, I promise you." Ding Yi said solemnly: "If the person you introduce is really useful, no matter how difficult this promise is, I will definitely do my best."

Thinking about this matter many years later, Ding Yi must regret that he promised so readily.

Overjoyed, Avi quickly turned around and asked someone to call Mito.

"Abbas—Mito, pay your respects to General Mingguoding." Mito folded his hands under his stomach, bent slightly, lowered his head, and raised his head quickly.

Although he was blind in one eye, he had a calm demeanor and a good temperament. Ding Yi knew at a glance that this man must be a nobleman in Persia.

"Hello, Mito, I heard that you have a lot of research on oil?" Ding Yi asked with a smile.

"Is it called oil here in Daming? Well—" Mito nodded: "I have been interested in oil since I was a child."

"In our country, the royal palace and noble officials' homes will use oil extracts to light lamps, and the special wicks can last forever. A long time ago, the Persian Zoroastrianism called this kind of flame the holy fire."

Ding Yi was overjoyed, walked down from his seat, and took his hand happily: "Go, go and have a look, do you know how to refine and use it?"

"Of course, I've liked this since I was very young, it's my hobby." Mito laughed.

Not long after, Avi, Mito and Ding Yi came to a basement.

The two didn't expect that Ding Yi would store the oil in the basement, but it was obviously the right thing to do.

Oil cannot withstand high temperatures and is best kept in the basement.

They found that the place where Ding Yi stored oil was far away from Tainan City, and it took more than ten minutes to ride a horse. When they arrived at the scene, they found that it was at the foot of a mountain, surrounded by soldiers, but there were not many soldiers and horses.

There are small defenses on the left and right in front of the cave, each with a 12-pound cannon and a dozen gunmen.

There is only a team of fifty soldiers here. The defense force is not much, but it is absolutely strong. As long as there are enough guns and shells, thousands of people may not be able to attack.

There is an iron-wooden door between the two forts, which is very heavy. After opening it, you walk into the passage, and then go along the passage to the basement.

The excavation below is very large, and there are still many workers continuing to work.

They passed a storage room and saw that the oil was packed in barrels and handled in an orderly manner. When Avi heard someone transporting them, making a light and crisp sound, he knew that those barrels were made of iron.

Then everyone walked through the passage in the mountain and went to the back of the mountain.

There is another cave here, surrounded by mountains, with houses built in the middle, and many workers and craftsmen are here.

There is a relatively far distance, a separate house is used to study oil, the whole body of this house is built with large pieces of bluestone, it is estimated that it is afraid that the explosion will spread to the surrounding area.

All the bluestones were dug from the surrounding mountains and erected on the spot.

One can tell that Ding Yi has put a lot of thought into it.

The more they watched, the more they felt that General Ming Guoding was very methodical, careful and serious in doing things.

Ding Yi led them into the stone house: "My people are researching here, but they have no clue."

Ding Yi also has a little understanding. Oil seems to need to be heated to decompose, but how to heat it is hard to say, so the craftsmen and technicians can only mess around here, and it exploded twice. After the explosion, everyone was scared. Be more and more careful now.

After Mito came in, he took a look and smiled: "General Ding's idea is right. The oil needs to be heated, but your method of heating is wrong. If the temperature is too high, it will be dangerous."

According to the current saying, it is to use heating method to distill and separate gasoline, kerosene, diesel oil, asphalt, petroleum gas and so on.

They used asphalt to pave roads in Persia in the 8th century, and Mito was interested in this and studied it for many years.

He said: "We are going to make a fractionation tower and a fractionator, and we need to use glass. I wonder if there are any craftsmen here who can make glass?"

"Yes, yes, of course." Ding Yi was ecstatic. The so-called expert will know if there is one as soon as he makes a move.

As soon as Mito opened his mouth, Ding Yi knew that he really understood.

He immediately called Miao Weidong, the person in charge here, and from now on, everything will be under Mito's command, and Mito will supply whatever he needs.

Miao Weidong nodded repeatedly.

But at this time another problem was involved. Mito could not speak Chinese, and now that Avi was here, the two sides could communicate.

Avi immediately said, I have an interpreter on board, and leave one for you.

After that, Awei didn't stay for long. He exchanged a lot of carpets for sugar, and Ding Yi gave him another [-] catties.

Finally, he left Da Yuan with [-] catties of sugar. He will pass through the Ming Dynasty to Japan, and he will pass here when he returns from Japan to see Mito.

Awei is very smart, and he asked Ding Yi specifically, is there anything he needs to bring back from Japan or the Ming Dynasty?He can drop by.

Ding Yi thought for a while: "I need craftsmen and population, these are the things I'm most in short supply."

Avi nodded thoughtfully.

Ding Yi could clearly see that this Awei valued Mito very much, and was even willing to help Ding Yi with things for Mito. Ding Yi felt that Mito's identity was certainly not simple.

But this time he was too far away from Persia, and he had no idea what was going on there.

Even if you know it, you will be beyond your reach.

But he thinks it is a good sign, maybe, the future will be good for everyone.

After Awei left, Mito concentrated on building the studio. Ding Yi originally planned to return to Lushun, so he also came to visit for a few days, mainly to learn, and at the same time strictly ordered Miao Weidong and the others to learn.

Mito is also willing to teach them, unlike the craftsmen of the Ming Dynasty, most of them don't like to teach others.

Because it takes time to make a fractionator and a fractionator, Mito drew pictures in the early stage and asked the glass craftsman to do it.

After Ding Yi comes, he will explain to Ding Yi.

Ding Yi also understood quickly.

Mito uses mud bricks and iron barrels for heating. The main thing is to control the temperature. It should not be too high or too low. If it is too low, it can only separate gasoline and diesel, but cannot separate asphalt. If it is too high, it will naturally be more dangerous.

There are no thermometers in this era. After many experiments in the past, Mito used fixed thick iron and mud bricks, set the time for burning, then lowered the flame, kept the temperature for a period of time, and then observed the speed of oil and gas separation, and used the speed to roughly judge the temperature. (According to modern industry, it is about four or five Baidu)

When necessary, you can also use cold water to cool down. It is better to lower the temperature, slow down, and not too high.

Petroleum is slowly refined at such a temperature, and finally turns into steam and then enters the fractionation tower.

In the fractionation tower, it is divided into several layers, the higher the position, the lower the boiling point.

Petroleum vapor gradually liquefies, cools and condenses into liquid fractions as it rises.

The gaseous fraction with a lower boiling point slowly rises up the tower and condenses at the upper layer of the tower, such as fuel gas, liquefied petroleum gas, light oil, kerosene, etc. In layman's terms, this is relatively light, and the lightest is in the On the top.

Then the liquid fraction with higher boiling point is condensed at the bottom of the column, such as diesel oil, lubricating oil and wax.

There is also a layer of sticky residue that will be left at the bottom of the tower, which is bitumen and heavy oil, which can be used as raw materials for coking and bitumen production or as boiler fuel (good for iron and steel making).

Different fractions are collected in each layer, and then transported to the fractionation tower through conduits, so that different substances such as gasoline, kerosene, gas, diesel oil, lubricating oil, and asphalt can be obtained.

When Mito did his research, he mainly wanted to get gasoline, kerosene, etc., but Ding Yi immediately thought of asphalt, lubricating oil, wax, etc. when he said that.

Asphalt can be used to pave roads, lubricating oil can be used on his machinery, and wax is often used in daily life.

When Ding Yi said this, Mito also learned new knowledge. All the separated things are useful. Before he was in Persia, many things were directly thrown away.

At this time, the fractionation tower and fractionator have not yet been completed, and Ding Yi is already very happy. The completion of this matter is definitely a great progress in human industrialization, enough to be included in the epic.

The most important thing to do this is to control the temperature. Too low or too high will not work. If it is too high, it will easily ignite and cause an explosion. This is why they exploded when they did it by themselves.

Because he wants to separate more points at one time, the fractionation tower and fractionator will be made larger, and Ding Yi has no time to wait. After learning the whole process, he is going to return to Lushun at the end of the month.

Before returning to Lushun, he summoned Amakusa Shiro from Japan.
