Problems with the cycle hydrogen compressor in coal tar hydrogenation units
Thread Content
During the commissioning of the coal tar hydrogenation unit, both hydrogen circulation pumps were operating normally. However, when the catalyst in the reaction system was being dried, one of the hydrogen circulation pumps failed to increase pressure. I’m not sure what the cause is; please help analyze it
The changes in process conditions you mentioned should not have an impact on the new hydrogen machine; it’s probably a purely mechanical issue
Check the valve disc, spring, and sealing surface of the gas valve to see if there are any problems
Check the valve disc and the inlet filter. The circulator is not a pressure booster; it’s better to say that it cannot achieve the desired flow rate, rather than saying that \"there is no increase in pressure.\"
Is your pump reciprocating? It should be a problem with the engine unit.
Poster: The circulating hydrogen compressor is used for gas circulation, with a low outlet pressure. The new hydrogen compressor requires a higher pressure: lol
