Is the load control of the cycle hydrogen compressor and the fresh hydrogen compressor in hydrogenation controlled by which process signal?
Thread Content
It is said that the gas flow rates delivered by the recycled hydrogen compressor and the new hydrogen compressor are related to the process parameters, but in terms of actual control, which process instrument signals are used to regulate the compressor load?
The load control of the cycle hydrogen compressor and the new hydrogen compressor relies primarily on hydrogen flow and pressure signals for regulation. Specifically, the operating speed or on/off status of the compressor is adjusted based on the feedback signals from flow meters and pressure sensors, to ensure that the hydrogen supply meets the process requirements. .

You must be referring to variable frequency control, right? The motor speed is controlled via hydrogen flow or pressure signals to meet the process requirements. The load on the compressor itself can be determined by the current.
The circulating hydrogen compressor controls the amount of hydrogen mixed in and the feed rate to the unit, based on the hydrogen-to-oil ratio of the unit and its processing capacity, in order to maintain a relatively stable hydrogen-to-oil ratio. The load of the new hydrogen machine is adjusted based on the hydrogen consumption, by maintaining a relatively stable pressure to increase or decrease its load. As for how to adjust the load of this machine, it depends on the method used for such adjustment – it may be done through frequency variation, using a margin, via a return line, or through a combination of these methods.
New hydrogen compressors are generally controlled via a return line based on system pressure
