The inlet temperature issue of two-stage hydrogen compressors
Thread Content
If the pressures are roughly as follows: inlet pressure at stage 1 is 0.1 MPa, exhaust pressure at stage 1 is 0.28 MPa, exhaust pressure at stage 2 is 0.8 MPa, and the volume flow rate is 16 cubic meters per minute, what are the typical temperatures of the inlet air at stage 1 and stage 2 for such a compressor? Is it reasonable to assume that the inlet temperature is around 20 degrees for the first stage and 30 degrees for the second stage?
Generally, the inlet temperature for stage 1 is below 20 degrees, with a maximum of 20 degrees, while the inlet temperature for stage 2 is below 30 degrees, with a maximum of 40 degrees.
Thanks to the person above! Well, the intercooler cools hydrogen from 130 degrees to 25 degrees, right? That shouldn’t be difficult to achieve
The determination of the inlet temperature should be constrained by the exhaust temperature and gas volume, as well as by whether the compressed gas will condense in order to prevent cylinder collision. Generally, a heating device is installed; if this is acceptable, then there should be no problems. In our facility, the inlet temperature of the compressors in the hydrogenation unit is usually maintained between 40 and 20 degrees Celsius.
