Chapter 806
"Yang Jin, why did you take off your shoes!" Yang Jin's aunt suddenly shouted.

When Yang Dongsheng took a look, he saw that Yang Jin had taken off his shoes and was breaking off his toes.

Yang Jin's mother immediately gave Yang Dongsheng a big roll of her eyes.

As a child admitted to university from the countryside, although Yang Dongsheng did not dare to claim to be a top student, he has never been embarrassed by his studies.

The teachers he has experienced, not to mention junior high school and elementary school, even high school teachers, many of them are mixed.

The math teacher will only list a formula, tell you that the calculation has no technical content, and let you calculate the result by yourself.

Students can't figure it out at all based on the formulas he listed.

The English teacher will only copy the writing on the blackboard according to the standard answers.

The student asked him why, and he said it was like this, just remember it.

……

Teachers are fooled in various ways, and students can only rely on their talents.

It is not easy for every child who can be admitted to university from the countryside!
Lying on the bed at night, Yang Dongsheng called up the three-dimensional map, and the mines and steel plants on the Grain Coast had already started production.

In addition to iron ore, gold, diamonds, and the coking coal and combustible ice that Yang Dongsheng transferred.

In fact, the Grain Coast still has good oil reserves, and there are typical oil storage structures near the coastline.

However, Yang Dongsheng will not develop these oil fields in the short term. It is fine if crude oil is not found on the grain coast. If crude oil is found and there are still a lot of reserves, someone will drive an aircraft carrier to protect XX.

Yang Jin's mother suddenly said, "I want to find a good tutor for Xiao Jin, and I can't start falling behind now. Ask someone to ask, is there any famous tutor?"

"I think..." Yang Dongsheng thought for a while, "It's more important to give Xiao Jin a smart younger brother or sister while you are young! Learning this is really a test of talent, otherwise those students in your class, if you are How many children with eight classics take the college entrance examination can be admitted to university?"

The complete process flow of ethane steam cracking to ethylene includes three parts: cracking, compression, cooling and separation.

In the cracking part, the preheated ethane and steam enter the cracking furnace and crack at a high temperature of [-] to [-] degrees.

The cracked gas at this time not only contains ethylene, but also a large amount of by-products such as hydrogen, methane, propylene, butadiene.

After the cracking is completed, the cracked gas is quenched to [-] degrees to avoid further decomposition of ethylene.

The cracked gas then enters the turbo compressor for multi-stage compression to remove acid gas and residual moisture.

The by-product high-pressure steam produced by quenching cannot be wasted, and will be sent to the turbo compressor to do work.

The dry cracked gas will be further cooled and compressed.

Since the boiling point of hydrogen is as low as minus 252.78 degrees, which is much lower than that of ethylene, methane, propylene and other gases in the cracked gas, it will be separated first.

The cooled liquid will be sent to a rectification column to separate products such as methane, ethylene, propylene, butadiene.

They can't plug in the cracking furnace, but after the cracking furnace, refrigeration devices, compressors, pumps, valves and other equipment are needed.

Storage of these products requires cryogenic containers.

Driving the compressor requires an industrial steam turbine.

Methane, one of the by-products, can be used to generate electricity, requiring small and medium-sized gas turbines.

In addition to ethylene production-related equipment, petroleum groups and petrochemical groups also purchase a large number of diesel engines, motors, transformers, bearings every year...

The purchase amount is at least several billion, or even tens of billions, every year.

These devices are all Dongsheng Heavy Industry is good at, and have passed the relevant technical appraisal long ago.

The price is cheaper than foreign equipment, and the quality is not inferior to them.

Compared with other domestic manufacturers, the quality is at least one grade higher, but it has not entered the procurement system of petroleum groups and petrochemical groups.

In the final analysis, the current domestic petrochemical industry is highly concentrated in the hands of several major state-owned enterprises.

They have their own subsidiaries, and they should take care of the subsidiaries first.

What the subsidiaries can't produce are often some high-tech equipment. At this time, they will give priority to purchasing imported products.

These major state-owned enterprises are all supported by the state, and they don't have to worry about the dollar.

For them, using domestic equipment can indeed save money and foreign exchange, but the saved foreign exchange cannot be put into their pockets.

In case something goes wrong, the stick will actually hit him on the ass.

Using foreign equipment is different. Even if something goes wrong, they can also shirk it—they used to be good before, and foreign countries also use these equipment...

So even if they know that domestic equipment is cheaper than imported equipment, they are willing to use expensive imported equipment.

Yang Dongsheng didn't intend to take too much food from the subsidiaries of the petroleum group and the petrochemical group this time. These subsidiaries are all his own sons.

Once too much is seized, it will cause dissatisfaction with the oil group and petrochemical group.

But he must take this opportunity to completely replace imports, which are truly high-end, high-profit products.

Once the petroleum group and petrochemical group purchase, it can also form a demonstration effect and drive other companies in the petrochemical industry to use Dongsheng Heavy Industry's products.

In terms of mine compensation, Petroleum Group, Petrochemical Group, and Shanbei Oilfield will provide some oil wells.

Major coal provinces such as Jin, Liao, Lu, Hei, Henan, and Shaanxi will also provide some coal mines.

In recent years, the coal market has been doing well.

But since 2004, XXX accidents have happened one after another.

The state has repeatedly imposed restrictions and rectifications, but to no avail.

If they were only asked to take out coal mines, they would definitely encounter great resistance. Now that the provinces are asked to exchange coal mines for the ethylene industry to land, the resistance will be much smaller.

In addition, although domestic natural gas is poor, the output has also increased a lot in recent years, mainly concentrated in several western provinces such as Sichuan, Shaanxi, and Xinjiang.

In this life, the eastern region no longer needs natural gas from the west as it did in the previous life.

It just so happens that provincial capital cities like Rongcheng and Chang'an are located in basins, which are very prone to large-scale pollution, so the country decided to simply build gas-fired power plants in these areas.

Originally, there were only cooperation projects between Dongsheng Mining, two major oil companies, and several cities, and they were directly upgraded to more than ten provinces such as Jiangsu, Shandong, Henan, Anhui, Sichuan, Shaanxi, Shanxi, Mongolia, Guizhou, Jiangxi, Xinjiang, and Chongqing. City, as well as the cooperation projects of the five major power generation groups.

The details were negotiated within a few weeks, which is very fast for such a wide-ranging cooperation.

After this time, the number of oil wells in the hands of Dongsheng Mining exceeded 4. In terms of the number of oil wells alone, Dongsheng Mining is already the third largest oil company in the country.

Based on this amount, 5000 to [-] million tons of crude oil is extracted every year, sitting on the throne of the third barrel of oil in the country, or even the second barrel of oil, which should not turn the oil group and the petrochemical group into trouble.

At this time, a cigarette case was pushed in front of him. Yang Dongsheng raised his eyes and saw that it was Li Rufeng who handed it over.

Li Rufeng took out a cigarette by himself, lit it, took a deep breath, and suddenly asked, "Which province in the central and western regions do you think has the most potential for development?"

Yang Dongsheng was taken aback for a moment, and immediately understood the meaning of Li Rufeng's words, "Are you going to release it?"
