Originating in the era of high oil prices in the 1990s, the coal chemical industry boomed in China. As a leading coal chemical industry, large-scale coal gasification technology used to be controlled by people for a long time, making the huge Chinese market an exclusive feast for foreign companies. However, this situation has finally changed today.
An advanced large-scale coal gasification technology, China Multi-Slurry New Gasification Technology (MCSG), demonstrating China’s own technological capabilities has risen rapidly in recent years. In contrast with foreign technologies, it has become an eye-popping industry and has become a coal chemical industry. One of the mainstream technologies in the industry.
This inventor with independent intellectual property rights technology is the pioneer of China's coal gasification technology development - the Northwest Institute of Chemical Industry in Xi'an. The rise of the new coal chemical industry has allowed the Ministry of Chemical Industry directly under the Ministry of Chemical Industry, which has devoted more than 30 years to the development of coal gasification technology, to accumulate a lot of achievements. It has become increasingly famous in the industry and coal gasification technology of China's independent intellectual property rights has finally come to the market. "The right to speak". This is a breakthrough in the independent innovation of the Northwestern Institute of Chemical Industry and a historic turning point for the Chinese coal chemical industry.
According to rough statistics, in only two or three years, the Northwest Research Institute of Chemical Industry successively signed 18 large-scale synthetic ammonia, methanol, and coal companies in Inner Mongolia, Shanxi, Shaanxi, Xinjiang, Guizhou, Anhui, and Shandong. Most of the coal gasification technology transfer contracts for oil projects have already started construction. The use of new multi-component slurry slurry gasification technology in Shandong has been completed and put into operation, and the annual production capacity of 300,000 tons of synthetic ammonia and 200,000 tons of methanol per year have been stably operating. This project is a model project for the industrialization of large-scale advanced coal gasification technologies.
The 18 large-scale coal chemical projects that have been built or under construction mean that the new multi-component slurry gasification technology of the Northwest Research Institute of Chemical Industry has quietly sat on the top of the industrialization promotion performance rankings of various large coal gasification technologies. One's position.
Some people say that the Northwestern Institute of Chemical Industry had a good luck and caught up with the good time for the development of coal chemical industry and stepped onto the hot spot of the market.
In fact, people in the “Coal Gasification Circle†know that the new multi-component slurry gasification technology that has been launched in the coal chemical market today has embodied the efforts and efforts of the two generations of the Northwestern Institute of Chemical Industry for more than 30 years. When some domestic companies just started to pay attention to coal gasification technology more than ten years ago, as the first “national team†to develop large-scale coal gasification technology in China, the Northwest Research Institute of Chemical Industry has been exploring and trekking in this field for nearly two decades.
Despite being in a fiercely competitive industry, the Northwest Institute of Chemical Industry still feels fortunate for itself: “If we do not engage in independent brand development and independent research and development in time, we will not have the initiative to participate in international competition today if we do not stick to it and stick to it.â€
Opened the “Graduation Book†of the Northwest Research Institute of Chemical Industry. More than 30 coal gasification technology achievements and national and provincial and ministerial-level science and technology awards and dozens of national patents obtained at different stages have truly documented the history of their independent innovation. It also paved the way for success for the Northwest Research Institute of Chemical Industry.
With "autonomy" only "active"
The unusually lively coal gasification technology market in China is an arena for strong players. A project often has five or six competitors at the time of formal negotiations.
It is in such a multi-technology market that the multi-material slurry gasification technology and coal chemical market docking seem to be particularly successful. In the confrontation with the strong hand, the Northwestern Institute of Chemical Industry can become a winner, and its profound experience is: With "autonomy", there is "active".
One of the initiatives:
The core technology of independent innovation The Northwest Chemical Research Institute, as the “national team†of independent innovation in the field of coal gasification technology, when it decided to “independent brands, independent research and developmentâ€, was exposed to greater risks and pressures than technical cooperation, but it also avoided Technology development and marketing are subject to people.
The development of this large-scale coal gasification technology began in the 1960s. It has undergone laboratory exploration research and basic research, and has undertaken the national scientific and technological research plan during the “6th Five-Year Planâ€, “July 5th†and “Eighth Five-Year Plan†period. During the period, it took charge of the scientific and technological development projects of China Petrochemical Corporation and China National Petroleum Corporation and the different phases of the technical development of scientific research institutes of the Ministry of Science and Technology during the Tenth Five-Year Plan period. Based on the completion of intermediate tests and industrial demonstration tests, the new multi-slurry slurry gasification technology successfully implemented industrial applications in Zhejiang in 2001.
This technology is characterized by adopting the concept of wet entrained flow gasification to form a multi-component slurry by optimizing the compounding of carbonaceous materials such as coal, petroleum coke, and petroleum pitch, and oils (crude oil, heavy oil, residual oil, etc.) and water. The slurry and oxygen are instantaneously vaporized by mixing through nozzles. The technology has the characteristics of wide adaptability of raw materials, advanced gasification indicators, mature and reliable technology, and low investment costs. The entire process and slurry preparation, additive technology, nozzles, gasifiers, gas aftertreatment systems, etc. have obtained 8 national patents. .
Has its own intellectual property rights, providing a "core" guarantee for the large-scale industrial application of the technology. The advanced nature of the new gasification technology of multicomponent slurry is equivalent to that of foreign technology, but the technology use fee is only a quarter of that of foreign technology and it has a stronger competitiveness.
Even in the process of industrialization and promotion, the hospital has never stopped the pace of innovation in multicomponent slurry gasification technology. According to different raw material characteristics, different target products, different device scales, and different requirements of users, they designed different gasification pressures and gasifier furnace types, and achieved “according to local conditions and tailored clothing†to form the leading technologies and applications. Closely-combined technology, multi-level technological innovation system.
When the Northwest Chemical Research Institute “fired up†in the coal chemical market, some famous foreign companies began to visit and expressed their desire to cooperate in the development of new coal gasification technologies. However, the Northwest Research Institute of Chemical Industry has always adhered to the principle that cooperation can, but Mainly to me.
The second initiative:
Industrial technology that users feel comfortable with At present, there are many advanced technologies in the coal gasification technology market, but not all are mature and reliable industrial technologies.
For the new multi-component slurry gasification technology, the advanced entrained bed technology, investment is lower than the introduction of technology, energy conservation and environmental protection, these hard indicators are undoubtedly an important reason recognized by the market. However, another key reason for users to give high scores to the new gasification technology of multi-component slurry is that this technology is down-to-earth in the process of industrialization and application, and the gasification pressure is from low to high. , Coal chemical projects from synthetic ammonia to methanol and coal to oil in a multi-field development process. The mature industrial technology with advanced nature and reliability allows the owners of coal chemical projects to use their confidence.
The new multi-component slurry gasification technology has been applied successfully since the first industrialization project in 2001 and has been applied in more than ten industrial installations, including an annual output of 30,000 to 300,000 tons of synthetic ammonia and an annual output of 200,000 to 600,000 tons of methanol. With an annual output of 160,000 tons of coal oil-making devices, four of them have been successfully put into operation and have been operating smoothly. The industrial equipment adopting this technology has a slurry concentration of 60% to 68%, a single furnace daily coal injection volume of 750 to 1800 tons, a gasification pressure of 1.3 to 6.8 MPa, an effective gas content of 80% to 86%, and a specific oxygen consumption of 400 Nm3/1000 Nm3. (CO+H2).
Almost every large-scale coal chemical plant in China has the supporting technology or technical services of the Northwest Research Institute of Chemical Industry.
The initiative three:
Industry-leading comprehensive technical services With more than 30 years of profound technical know-how in the field of coal chemical industry, the quality of technical service of Northwest Research Institute of Chemical Industry is second to none in the industry, and in particular, all free service models based on customer satisfaction are even more open. The first in the industry.
In the process of the construction of the owner's project, the Northwest Research Institute of Chemical Industry conducts every project as a model project: tracking the entire process of the equipment construction phase, providing free technical guidance after the completion of the trial installation, and providing the coal gasification process software package for users free of charge. Provides proprietary equipment construction drawings, free training for owners, free on-call service... Their first industrialized application customer has so far “enjoyed†free services for 6 years.
The hospital is also unique in its pre-phase technical services for coal gasification projects. They have conducted more than 100 coal sample tests for coal chemical projects each year. At present, more than 1200 coal samples have been evaluated for different gasification performance, gasification methods, and comprehensive coal utilization, and a gasification performance database has been established. It became the "first business card" for domestic coal evaluation. In addition to coal samples from all over the country, but also from Vietnam, Indonesia, Malaysia, Mongolia, North Korea and other countries. The complete set of test data obtained by coal chemical users can be directly used as a design basis, saving the cost of a large number of coal trial burns.
Continuing innovation won the initiative In recent years, the Northwest Institute of Chemical Industry has made exciting achievements in the coal gasification technology market, but they are fully aware that the key to being able to break through the “encirclement and suppression†in the fierce market competition is to take the first step. And after decades of unremitting efforts, the formation of independent intellectual property technology. Faced with the current situation of China's coal chemical technology market, the sustainable development of independent technology will only have lasting vitality.
From the various “titles†of the Northwest Research Institute of Chemical Industry, we can see their mission: coal water slurry gasification and technical support units of the National Engineering Center of Coal Chemical Industry, the core member of the Midwest Coal Gasification Engineering Center, Shaanxi Province Coal Chemical Engineering Technology Research Center, etc.
As the pioneers of the independent innovation of coal gasification technology in China, their greatest desire is to make this country invest a lot of capital, manpower, and material resources for decades. The independent intellectual property rights set of technology formed by more than a dozen research institutes and enterprises has been formed. , to promote the application in a wider range. In the process of continuous innovation of coal gasification technology, it continues to receive national and various policy support.
Coal is a kind of resource with complicated causes and composition. Only in China, the degree of deterioration, ash melting point, and ash content of coal in different regions are different, and there is no coal gasification technology that can “conquer the worldâ€.
At present, China has become the "hot spot" of the world's coal chemical industry. The Northwest Research Institute of Chemical Industry is not complacent about the successful industrial promotion of mature technologies. On the one hand, they did not stop further expanding the range of raw materials and process optimization and innovation of the new gasification technology of multicomponent slurry, especially the development of solid slag gasification technology, which will account for about 40% of the high ash melting point of coal resources in China. Coal is used effectively. On the other hand, the research on the dry coal gasification technology that started in the 1980s is being promoted to industrialization through close cooperation with large-scale enterprises and design institutes. At that time, the Northwest Institute of Chemical Industry will become the "all-weather multi-climate force" in the field of coal gasification, and continue to lead China's independent coal gasification technology.
