Ethylene "three machines" (ethylene compressors, propylene compressors, cracked gas compressors) are the core equipment of ethylene plants. At present, ethylene plants in the world are moving in the direction of large-scale, energy-saving and high-reliability. Some developed countries have completed the design, manufacture and complete sets of 600,000 to 1.5 million tons/year of ethylene devices. Prior to this, China did not have the performance of a large-scale compressor unit designed and manufactured independently for 1 million tons of ethylene.
Due to the rapid development of China's national economy, it has greatly stimulated the market demand for ethylene products, and domestic ethylene production companies have newly built or expanded large-scale ethylene plants. To this end, in early 2006, the State Council promulgated the Outline of the National Medium- and Long-Term Scientific and Technological Development Plan, listing large-scale steam cracking ethylene production technology and equipment as one of the priorities for the development of the manufacturing sector. In 2006, China's "Special Plan for the Medium and Long-Term Development of the Ethylene Industry" clearly pointed out: During the "11th Five-Year Plan" period, the country will carry out the second and third rounds of expansion and expansion of Maoming Petrochemical, Shanghai Petrochemical, Fushun Petrochemical and other enterprises. At the same time, the optimization of technical and economic indicators will enable the production of ethylene in these enterprises to reach or approach 1 million tons per year. Therefore, the successful conclusion of the contract for the development of the Shengu 1 million-ton/year ethylene cracked gas compressor unit will lay the foundation for the nationalization of the major technical equipment for the reconstruction and expansion of the next ethylene plant in China.
According to reports, Shenyang Blower (Group) Co., Ltd. is the largest company in China that integrates scientific research, development, design, and manufacturing. It is the only company in China that can develop large-scale ethylene equipment, cracking gas compressors. Its products are widely used in petroleum, In the major technical equipment of various industries such as chemical industry, electric power, metallurgy, and national defense. In 2004, Shenyang Drum Brand Centrifugal Compressor was rated as China's famous brand product; in 2006, Shengu Group was honored as an advanced collective that made significant contribution to the nationalization of major national technological equipment by the National Development and Reform Commission.
Multi-million-ton Ethylene Cracked Gas Compressor Combination Signed
On April 12, Shenyang Blower (Group) Co., Ltd. developed a cracking gas compressor combination for the 1 million tpa ethylene plant of Sinopec Tianjin Branch. The signing ceremony was held in Shenyang. This indicates that the development and development of major technical equipment in China will once again make substantive progress. After the success, it will fill the gap in the manufacture of compressor units for large ethylene plants in China with a capacity of 1 million tons per year.
