Compressor pressure issues
Thread Content
I have an ammonia compressor in my setup, which is used to compress ammonia; it has two cylinders. The inlet temperature at the second stage is 30 degrees, and the pressure is 0.8 MPA. Is ammonia a liquid under these conditions? If so, can the compressor still operate?
The saturated vapor pressure at 30 degrees is 1.09 MPa. I’m not sure if it is
The saturated vapor pressure at 30°C seems to be 1.167 MPa.
A pressure of 0.8 MPa corresponds to a temperature of less than 20°C; since the current temperature is 30°C, it’s impossible for it to be in liquid form You can check the “ammonia temperature and pressure chart”!
Under these temperature and pressure conditions, it is a gas
