Compressors have a long way to go, both challenges and opportunities!

The petrochemical industry is an important foundation and pillar industry of the national economy, and plays an important role in the development of macroeconomics. The compressor has played a key role in promoting the development of the petrochemical industry. Compressors are the key equipment of petrochemical plants. Most petrochemical plants have gas compressors. Therefore, compressors, as the "heart" of petrochemical equipment, play a very important role in the development of the petrochemical industry. In the petrochemical industry, centrifugal compressors, reciprocating compressors, and screw compressors are commonly used.


Petrochemical companies at home and abroad are all focused on the construction of a number of production facilities to form large petrochemical industrial zones. In the zone, the oil refining unit is a "leading", which provides cracking raw materials for petrochemical units, such as light oil and diesel, and produces petrochemical products; cracking units produce basic petrochemical raw materials such as ethylene, propylene, benzene, xylene; etc .; The series of production equipment for the production of synthetic materials and organic raw materials is mainly described as raw materials, and their products and raw materials have a certain proportion. If an annual output of 300,000 tons of ethylene is required, roughly 1.2 million tons of cracked raw materials will be required, corresponding to the processing capacity of the refinery of about 2.5 million tons, which can be used to produce 800,000 to 900,000 tons of synthetic materials and basic organic materials. It can be seen that a large amount of capital must be invested in the construction of the petrochemical industrial zone, and the plant site must be properly selected. Not only must the transportation of raw materials and products be ensured, but also sufficient power, water supply and other supporting infrastructure engineering facilities. Each production facility requires a large number of standard, qualitative machinery, equipment, instruments, piping, and non-specific special equipment.


Compressors are the key equipment in the petrochemical industry. A new set of 10 ton / year oil refinery will need 30 to 40 compressors, and a new set of 1 ton / year ethylene plant will need 40 to 50 various compressors. With the increasing scale of petrochemical equipment, petrochemical compressors are currently developing in the direction of large-scale, complete sets, high efficiency, integrated mechanical and electrical, energy saving and environmental protection, high reliability, and low noise. If the efficiency of large compressors is increased by 1%, annual operating costs can be saved by 5 to 8 million yuan.
