What should be paid attention to in the design and use of carbon 2 oxide compressor

The working principle is that the intake system stores the carbon dioxide gas in the cylinder, and the carbon dioxide compressor pressurizes the carbon dioxide gas through the reciprocating piston movement. After reaching a certain pressure, the pressurized carbon dioxide gas is transported out by the exhaust system.

A carbon dioxide compressor is a compressor used to pressurize and transport carbon dioxide gas.

Mainly used in urea synthesis equipment. Attention should be paid to the following when designing and using:

(1) Carbon dioxide has a high critical temperature and can be liquefied at 31.3 degrees Celsius and 7.14 MPa. When used in winter, the interstage cooling temperature cannot be too low;

(2) When the carbon dioxide is below 60 MPa, it is conducive to the compression of the gas;

(3) Due to the high relative density of carbon dioxide gas, it is not advisable to use an excessively high average piston speed, otherwise the valve resistance will be large;

(4) Carbon dioxide gas contains a small amount of water and is highly corrosive, so the gas valve, cooler and buffer tank must be made of stainless steel.
