What is the principle behind cold high and low pressure centrifugal separators in hydrocracking?
Thread Content
How exactly is the gas separated by centrifugation after being extracted from the cold high and low pressure areas? I hope experienced folks can give me detailed guidance: loveliness:
The process you described doesn’t seem to be common; it should be such that the gas produced at high temperature is cooled first, and then sent to a cold high-pressure separator. The gas coming out of that separator is then subjected to hydrogen desulfurization. It seems that centrifugal separation isn’t used in this process.
Is the poster referring to a coalescing separator?
Cold low-pressure gas is essentially the recycled hydrogen; generally, plants do not install additional centrifugal separators
The cold high-pressure gas is recycled hydrogen, while the cold low-pressure gas is sent to the low-pressure desulfurization unit! ! !
Haven’t heard of it! Don’t mislead people about the 6th floor! :lol
"Cold low-pressure gas is the recycled hydrogen; generally, plants do not install additional centrifugal separators. That statement isn’t correct – it should be that cold high-pressure gas is used for desulfurization of the recycled hydrogen
The cold high-pressure fractionate gas coming out of the hydrocracking cold high-pressure separator enters the circulating hydrogen desulfurization tower to have hydrogen sulfide removed, and then goes on to the circulating hydrogen compressor; whereas high-pressure centrifugal separators are used for the residue oil from hydroprocessing
What are the well-known suppliers of high-pressure centrifugal separators at home and abroad?
