Preface
On June 1, 2020, the world's first "3,000-ton super slurry bed forging and welding hydrogenation reactor" independently developed by mainland China officially appeared, which is the only one in the world and is also the dream of many European and American countries.
It stands to reason that with such technology, even if you sell equipment, you can make a lot of money, why doesn't the mainland sell it to the outside world?
3000-ton super slurry bed forged welding hydrogenation reactor
In today's scientific and technological development, oil resources are still an indispensable part of modern human beings.
At the same time, it is also one of the most important strategic resources, and once it leaves oil, the basic operation of the entire country will also be greatly affected.
The "3,000-ton super slurry bed forging and welding hydrogenation reactor" displayed by the mainland in 2020, this national "sharp weapon", will provide favorable help for the mainland's petroleum resources.
This sharp weapon was released by China First Heavy Group Co., Ltd. on June 1, 2020, saying:
"The world's first 3,000-ton super slurry bed Zhejiang Petrochemical forging and welding hydrogenation reactor manufactured by Dalian Nuclear Power and Petrochemical Co., Ltd. of China First Heavy Group was completed, shipped, installed and set sail. ”
As soon as this news came out, it attracted the attention of many domestic and foreign media.
Therefore, this equipment has set a new manufacturing record for forged and welded hydrogenation reactors in the world, and also proves that Continental is currently at the leading level in the world in the manufacturing technology of ultra-large tonnage petrochemical equipment in China.
This equipment weighs more than 3,000 tons, so it is also known as a 3,000-ton reactor, its length is more than 70 meters, the thickness of which reaches 0.32 meters, the outer diameter reaches 6.15 meters, and it is currently the world's heaviest slurry bed forged and welded hydrogenation reactor.
As the world's first 3,000-ton super slurry bed forging and welding hydrogenation reactor of Zhejiang Petrochemical, it will be the core equipment of the second phase of the 40 million tons/year refining and chemical integration project of Zhejiang Petrochemical in mainland China.
Needless to say, it is difficult to manufacture such a large-tonnage hydrogenation reactor, and the production process also requires advanced cutting-edge technology, because its working environment is relatively special.
This "national weapon" created by China First Heavy Industries, its name is a hydrogenation reactor, which is a device used to promote the reaction between hydrogen and other substances.
And this kind of reactor is mainly used in a high temperature and high pressure environment, so the requirements for the equipment itself are very high, by adding hydrogen, so that the reactor is in an oxygen-like state, thereby affecting the efficiency of the reaction.
Therefore, hydrogenation reactors are widely used in petrochemical industry, chemical synthesis and hydrogenation reaction.
Why does the mainland want to build this "weapon of the country"?
Why did you create this weapon?
In fact, this is still related to the oil resources of the mainland.
The reserve-to-production ratio of the mainland's local oil is only 14.8, which means that the oil reserves are insufficient, and a large amount of expensive crude oil needs to be imported.
However, this kind of large-tonnage equipment only a few industrially developed countries in Europe and the United States have a certain manufacturing capacity, and the tonnage of these countries is incomparable with the 3,000-ton level developed by the mainland.
In addition, before the mainland did not develop a super-large tonnage, super slurry bed forged welding hydrogenation reactor, the equipment in these countries was very expensive, and the maintenance costs and costs in the later stage also needed to be considered after use.
Therefore, it is difficult to meet the needs of such a large scale on the mainland.
As a result, the mainland began the road of independent research and development very early, and the main role of this sharp weapon is to carry out deep processing of crude oil.
Why process crude oil?
In fact, the quality of crude oil is also very different, and the density of each place or each type of crude oil is actually different.
There are light crude oils with low density, but they are also more expensive in terms of selling price, and there are medium crude oils with moderate density, and the price is relatively moderate.
This is followed by heavy crude oils, which are the cheapest but have a very low oil conversion rate, and finally, extra-heavy crude oils, which are extremely dense and rich.
Although heavy crude oil and extra-heavy raw materials are very rich, including asphalt, paraffin, lubricating oil, coke, etc., which can be made into plastics, rubber, and even pharmaceuticals if extracted.
However, because the density of heavy and extra-heavy crude oil is too high, and the viscosity is high, and the flammability characteristics, the cost of refining these two types of crude oil is very high, and the extraction rate of usable crude oil is also very low.
As a result, many countries prefer to use more expensive light crude oil than heavy and extra-heavy crude oil, which is rich in energy.
In addition, heavy crude oil and extra-heavy crude oil are ten times more stored than light crude oil, so if the high processing cost of this crude oil can be solved, then it means that more oil resources can be obtained at a lower price.
As a large country with a relatively short supply of oil, the continent is also the country with the most cars in the world, so the demand for oil resources will also be greater.
As a result, the mainland began to independently develop the "big country heavy equipment", so the world's first "3,000-ton super slurry bed Zhejiang Petrochemical forging and welding hydrogenation reactor" was born.
So, how does this sharp machine work?
How does this sharpener work?
Hearing that this name and title are so long, I also know that this weapon must be very powerful.
First of all, we need to understand the processing process of heavy crude oil, in fact, compared to the processing of light crude oil, the most critical node of heavy crude oil is the "cracking reaction".
The so-called "cracking reaction" is actually to decompose these relatively large molecules into smaller molecules through this sharp weapon.
In fact, it is equivalent to breaking down a large stone into very small sand, and in this way, the production of various oils of heavy oil can be increased as much as possible.
And it can also filter out other "impurities", but this magazine also has many other uses, simply put, through this "national weapon", the value of heavy crude oil is developed as much as possible.
Therefore, this method has become the direction of many industrial countries since the last century, and having an advanced reactor means the degree of development of heavy crude oil.
Not only can oil resources be retained as much as possible, but more petroleum add-on materials can be obtained, i.e. bitumen, paraffin, coke and other raw materials.
However, if you want to achieve the high efficiency operation and conversion rate of this equipment, there are certain technical problems, so the hydrogenation reactor is the key equipment used to realize this reaction.
Therefore, due to various factors in the mainland, the mainland began to develop hydrogenation reactors for this super-large tonnage, and the larger the reactor, the more difficult it is to do, because all parts and components must work hard to produce and adapt independently, so as to be able to manufacture products that meet their needs.
Continental has continued to grow from 400 tons at the beginning, and finally realized the world's first 3,000 tons hydrogenation reactor in 2020.
So, does this "weapon of the country" solve the mainland's oil problem?
Domestic sharp weapons help the mainland solve the oil problem
In fact, after the accident of this sharp weapon, it successfully helped the mainland to improve the problems raised by oil resources.
With the blessing of this "3,000-ton super slurry bed Zhejiang Petrochemical forged and welded hydrogenation reactor", the conversion efficiency of heavy oil in mainland China has been directly increased to 85%.
If ordinary equipment is used, the conversion rate of this heavy oil will not even exceed 50%, and it is generally around 45%.
Therefore, with the blessing of this "domestic weapon", the conversion rate of heavy oil in the mainland has been greatly improved.
In this way, more oil resources have been obtained and the utilization rate of heavy oil has been pulled to a very high level, which has greatly improved the utilization rate of heavy oil on the mainland.
So, with the help of this sharp weapon - the problem of oil resources, the continent has been greatly improved.
Because of the blessing of this sharp weapon, the mainland's target for heavy oil is getting higher and higher, so China's oil production continues to increase in order to meet the domestic supply of oil resources.
Therefore, the economic value of this is actually very huge, after all, the production capacity has increased a lot of half.
Even if the input is a crude oil product of relatively poor quality, it can be better refined after being processed by this sharp tool.
Moreover, even unusable and obsolete optimized resources can be reused through this tool, so as to maximize the utilization of crude oil to a greater extent.
This is also the leading position of this core technology of the mainland, which has further improved the utilization rate of oil resources in the mainland.
This makes it possible to produce more gasoline, diesel, kerosene, lubricants, and other high value-added products, which are widely used in various fields, including energy, industry, medical, and agriculture.
Therefore, this machine not only realizes the problem of waste of resources, but also solves the problem of environmental pollution to a large extent.
Therefore, this "weapon of the country" has really affected many fields in real life, so it is of great significance.
However, with the delivery and application of this sharp weapon on the mainland, European and American countries are also very jealous, because the increase in the conversion rate of heavy oil is a problem for global industrial countries, who doesn't want to get more oil out!
Core technology is never sold
Therefore, it has attracted the attention of European and American countries, because the production capacity problem of heavy crude oil is a global problem, and they do not yet have such a powerful technology.
As a result, they have proposed to buy this 3,000-ton super hydrogenation reactor.
You must know that this is a reactor with an ultra-high conversion rate, and it is also unique in the world, so Continental said that this product will not be sold to the public.
First of all, this product, because it involves the core secret technology of the state, this technology is very important to the mainland itself.
Moreover, who would export such a powerful weapon to foreign markets not long after it was developed.
The mainland's current demand for oil resources is much higher than that of any other country, so it will ask for as much as there is for this sharp weapon.
Because it can alleviate the continent's oil energy problem to the greatest extent.
Just like a knife to cut a cake, there are so many resources in the world, and having this technology will also lead to lower prices for raw materials.
After sending this knife out, then not everyone is the same, then even cheap heavy oil will cause the price to rise for this reason.
Therefore, it is not only the core secret technology, but also in the future, and there are not many 3,000-ton hydrogenation reactors in the mainland, and they are not enough, so they are prohibited from exporting.
At present, "12 forging and welding hydrogenation reactors of more than 3,000 tons have been successfully delivered in April this year".
This means that Continental has the ability to manufacture major technical equipment for ultra-large petrochemical companies in batches and specialization, and has become the world's leading manufacturer of forged and welded hydrogenation reactors!
epilogue
The 3000-ton super slurry bed forged welding hydrogenation reactor is an extreme manufacturing that requires a pile hammer to replace the ring, so the requirements for the technical limit are very high.
Therefore, as the largest oil consumer, the mainland has such a powerful weapon, and it will also greatly improve the problems that the mainland is currently facing in terms of oil resources.
It will surely enable China's petroleum field to achieve corner overtaking and lay a solid energy foundation for the great rejuvenation of the Chinese nation.
