Vacuum compressor consultation
Thread Content
Hello everyone. . There is a vacuum on the front side (with an absolute pressure of around 0.05 MPa; the degree of vacuum is not high), and the pressure on the back side needs to be increased to 0.5 MPa. Can a vacuum compressor be created? During the pressurization process, a small amount of gas may liquefy, but as long as the temperature remains above 80°C, it stays in gaseous form. Looking for recommendations.
It is recommended to detail and comprehensively specify the required conditions, such as medium, flow rate, temperature, etc. For easy discussion and reference.
80% of the inlet is hydrogen, with 18% acetaldehyde and 2% ethanol. The inlet pressure is 0.05 MPa (gauge pressure), the temperature is around 40°C, and the flow rate is approximately 3000 standard cubic meters. The required outlet pressure is 0.5 MPa (absolute pressure). How to achieve it, thank you
The water ring compressor, with a back pressure of 0.5 MPa at present, has an air extraction rate of around 3000 m3/h (at the inlet condition). This requires two units to be used simultaneously, and the cost is very high.
No problem, our vacuum compressors can handle it
You have only one option; there are no other choices. It’s the liquid ring compressor. There are two companies whose products can meet this requirement well: GDNASH and NSB
Obviously, the designer of this condition chose it based on liquid ring compressors
Relying on a single pump to achieve both suction and discharge pressures results in low stability and efficiency. It is recommended to connect the two pumps in series.
