Regarding the issue of waste hydrogen emissions
Thread Content
Should waste hydrogen emission occur before or after the separation of circulating hydrogen in (reciprocating compressors)? Previously, with the unit in the front, was the gas flow rate of the cyclic hydrogen compressor stable? Now the unit is at the back, which allows some of the condensable oil to be recovered. Which one is specifically good
It is generally installed before the gas side of the recycled hydrogen separation tank. The circulating hydrogen buffer tank provides buffering for the flow rate and pressure at the inlet of the circulating hydrogen compressor.
The purpose of releasing waste hydrogen is mainly to improve the purity of the circulating hydrogen. I’m not sure what the original poster means by talking about recovering condensed oil – is your pipeline connected to the bottom of the tank?
The device located at the back of the exhaust gas line is generally used for the purification of recoverable hydrogen, and it doesn’t matter whether it is placed in front of or behind the machine. However, when it is placed at the machine inlet, it is more convenient for nitrogen replacement and hydrogen replacement during startup, as well as for ensuring airtightness. If it’s at the machine’s outlet and hydrogen is used for displacement, is it still necessary to depressurize the machine? I’m not sure whether the person asking has a pressure-reduction line in place before the machine.
It is generally better to do this after liquid removal, as this can reduce the impact of the emitted hydrogen waste on downstream equipment or gas pipelines
