Oxygen compressor issues
Thread Content
Why does a piston oxygen compressor require a much higher temperature for decompressing nitrogen when producing oxygen pressure? Is it because of the change in compression ratio? Isn’t nitrogen less dense?
Changes in the molecular weight of a gas affect the exhaust temperature of the compressor. When the molecular weight increases, the flow resistance rises, the isothermal compression efficiency decreases, and more energy is required, resulting in an increase in the exhaust temperature. Conversely, when the molecular weight decreases, the situation is reversed~~
The compression ratio has changed. The nitrogen outlet pressure is lower than that of oxygen.
