What are the effects of excessive pressure drop in a hydrogenation reactor? What are the causes? I’m asking experts to explain in detail
Carbon buildup affects the proper operation of the compressor
Why does it affect the compressor’s operation?
High pressure difference; high pressure at the compressor outlet
A large pressure difference means there is a big gap between the inlet and outlet pressures of the reactor; as a result, the subcooled fluid returns to the compressor inlet. This results in low pressure at the compressor inlet, and in order to raise it to the operating pressure, the workload on the compressor increases. Is this understanding correct?
What are the consequences of excessive pressure drop in a hydrogenation reactor? What are the causes? I need detailed answers from experts. The reasons for excessive pressure drop in a hydrogenation reactor include: 1) Blockages in the process pipelines before operation, resulting in high local resistance; 2) Excessive pressure drop during processing, caused by blockages in the catalyst bed, partial blockages in the heat exchangers, blockages in the air coolers, blockages in the high-pressure sections, blockages in the compressor inlet filters, and blockages in the compressor exhaust. Excessive pressure drop can lead to the compressor tripping due to overload, collapse of the catalyst bed, internal leakage in the heat exchangers, and complete blockage of the process pipelines. Once such problems are detected, it is necessary to identify promptly where the pressure drop is increasing
