Are the cycle hydrogen compressors used in hydrocracking and diesel hydrogenation both driven by steam?
Thread Content
May I ask, are the cycle hydrogen compressors used in hydrocracking and diesel hydrogenation driven by steam? Are there any that are driven directly by electricity, or are there other ways to drive them?
My workshop has two sets of equipment: one for hydroprocessing and one for hydrorefining, each equipped with a cycle hydrogen compressor. Both compressors are driven by 3.5 MPa steam. Given the large volume and high pressure of the cycle hydrogen, as well as the need for continuous operation to prevent the reactor bed from overheating, if electric drive were to be used, compressors or reciprocating pumps would have to be employed. However, this would result in a pulsed flow of cycle hydrogen at the outlet, which is discontinuous and can easily lead to overheating of the reactor bed. Overall, steam drive is more stable!
Here, we also use steam turbines for power

The recycle hydrogen compressors used in industrial production are all driven by steam, as using other power sources is very costly.
Are there any models that use a dual-drive system? ? ?
Our hydrogenation circulator is driven by a motor, along with a centrifuge
No, some of them are also driven by electric motors
It’s not entirely steam-driven; motors are also used for propulsion
