It is understood that, as with axial flow compressors and blast furnace gas energy recovery turbines, centrifugal compressors now have a wider range of applications and fields. China's petrochemical and other industries are also boldly adopting domestic centrifugal compressors in major projects. product. This shows that China's centrifugal compressor technology has begun to take a new step in terms of performance, efficiency, safety and reliability.
Shaanxi Blower (Group) Co., Ltd., the vanguard of China's fan industry, has been devoting itself to research and development of new technologies for many years to expand its market applications. Through the combination of production, study and research, Shaanxi Drum Group has formed the design, manufacture and complete sets of high-pressure special medium centrifugal compressors with independent intellectual property rights, and has designed and manufactured rich gas, synthesis gas, nitrogen oxide, carbon dioxide, recycle gas, natural gas, Hydrogen, gas, cracked gas, raw gas and other centrifugal compressors. At the same time, the company also has the ability to design and manufacture ethylene, propylene, purified terephthalic acid, and natural gas transmission centrifugal compressors.
Coal chemical industry
Occupy commanding heights
With the rapid development of China's economy, how to effectively take advantage of coal resources, optimize the energy structure, vigorously develop new types of alternative energy sources, and solve oil shortages and the resulting energy security problems have become issues that our government has attached great importance to.
China's coal resources are abundant, especially lignite accounts for a large proportion, but due to its low calorific value, poor quality and heavy pollution, it has greatly limited the application of lignite. However, lignite is easily liquefied and is the preferred coal for coal liquefaction. Therefore, it can be used for chemical production after liquefaction.
Recently, Shaanxi Blower (Group) Co., Ltd. won the bid for the first batch of raw material gas and finished gas compressor manufacturing in the domestic coal-based 200,000-ton/year ethylene glycol project. It has won the bid for the domestic application of compressors in the coal chemical industry. Opened the door.
The 200,000-ton/year ethylene glycol project is a high-tech project with full independent intellectual property rights developed by the Chinese Academy of Sciences and Shanghai Jinmei Chemical New Technology Co., Ltd. The project uses ethylene glycol as the raw material to make ethylene glycol, which is the first in the world. Therefore, after the project is successfully put into operation, it will play a positive role in the optimization of China's energy structure. Shaanxi Drum signed the contract for the production of raw gas and finished gas compressors for this project, which signifies that the application of centrifugal compressors produced by Shaanxi Blower (Group) Co., Ltd. has occupied the commanding height in the field of coal chemical industry.
It is understood that the development of China's coal liquefaction industry prior to 2010 will be dominated by engineering development and industrialization demonstration. After 2010, with the gradual maturity of domestic coal liquefaction engineering technology development and the accumulation of engineering operating experience, the industrialization of the technology will enter the second stage. Some experts predict that by 2020, the total coal direct liquefaction capacity in China will reach 16 million to 18 million tons per year, and the total indirect liquefaction capacity will reach 20 million to 23 million tons per year, which provides a broad market for centrifugal compressors. space.
Air separation area air compressor
Manufacturing to a new level
The air compressor unit is the key auxiliary equipment of the air separation unit, and the air separation unit is an important auxiliary equipment widely used in oil refining, ethylene, chemical fertilizer, coal chemical industry, metallurgy and other industries. At present, Shaanxi Shaanxi Blower (Group) Co., Ltd. 40,000 to 60,000 class air separation equipment, the main performance parameters and technical indicators have reached the international advanced level. In the next 5 to 10 years, with the construction of China's million-ton-class large ethylene, 10-million-ton large-scale oil refining, large-scale coal-to-olefin and methanol projects, and steel and thermal power projects, the market demand for very large air separation plants The amount will increase.
In order to seize market opportunities, Shaanxi Blower (Group) Co., Ltd. has continuously increased investment in scientific research and development in recent years, and strived to improve the technical level of design and manufacture of air compressor units, and achieved remarkable results. The company has the ability to design and manufacture compressors of 60,000 class air separation units, and its main performance parameters and technical indicators can reach the advanced level in foreign countries.
According to statistics, since 2002, Shaanxi Blower (Group) Co., Ltd. has provided more than 50 sets of air compressor units for chemical and metallurgical enterprises in Shandong Hualu Hengsheng and Jiangsu Linggu, with the market share ranking first in the country. .
Centrifugal Compressor Package Technology Shows Efforts in Various Fields
As the earliest enterprise in the industry for system technology and complete set of technology research and application, Shaanxi Blower (Group) Co., Ltd. has mastered system technology related to centrifugal compressors and sets of multiple units through research on process systems and multi-generators. Technology, has now designed and completed more than 200 sets of large-scale units. Including the largest engineering contracting project for the 270,000-ton/year nitric acid plant of Jinkai Group in China, the success of this project has laid the foundation for the rapid occupation of the domestic market by Shaanbi centrifugal compressors.
At present, Shaanxi Blower (Group) Co., Ltd. has produced more than 1,000 sets of centrifugal compressors and more than 20 sets of nitric oxide compressors for nitric acid plants, making it the only company in China able to independently design and manufacture 3-in-1 and 4-in-1 units of nitric acid. enterprise.
In the design and manufacture of high-pressure, special-media centrifugal compressors, Shaanxi Drum has gradually shifted from co-manufacturing to independent design and manufacturing. Among them, fully domestically produced raw gas (natural gas) compressors designed and manufactured for methanol plants, and fully domestically produced rich gas compressors designed and manufactured for refineries have been put into operation by a number of users. Recently, Shaanxi Drum successfully won the bid for the first fully domestically produced 100,000-ton/year coking gas-to-methanol engineering syngas compressor unit, marking a solid step in the localization of chemical high pressure real gas centrifugal compressors.
The facts show that the centrifugal compressors manufactured by Shaanxi Drum have begun to show their talents in many fields.
