Carbon oxide co2 compressor refers to the compressor used to pressurize and transport carbon dioxide gas. Mainly used for, 1. Recovery and storage of dry ice volatile gas in CO2 plant and recycling of waste CO2 in the plant, 2. Use the liquid characteristics of CO2 for industrial and pharmaceutical extraction process 3. Large carbon dioxide compressor is mainly used in urea synthesis unit Attention should be paid during design and use: (1) the critical temperature of carbon dioxide is high, which can be liquefied at 31.3 ℃ and 7.14mpa. When used in winter, the interstage cooling temperature should not be too low; (2) When carbon dioxide is below 60MPa, it is conducive to gas compression; (3) Due to the relatively high density of carbon dioxide gas, it is not suitable to use too large average speed of piston, otherwise the resistance of gas valve is large; (4) Carbon dioxide gas contains a small amount of water and is highly corrosive, so the gas valve, cooler and buffer tank should be made of stainless steel.
