Basis for determining whether to install a buffer tank in front of the new hydrogen compressor
Thread Content
Fresh hydrogen is free of liquid; there is no basis for installing a buffer tank in front of the fresh hydrogen compressor, and currently such buffers are generally not used with fresh hydrogen compressors. The reason for it. Is a buffer tank provided for the new hydrogen compressor in gasoline and diesel hydrogenation?
A buffer tank must be installed; firstly, to separate liquid from the fresh hydrogen, and secondly, to buffer the pressure at the inlet of the fresh hydrogen compressor. If liquid is accidentally carried in with the hydrogen supply, the consequences could be severe
There is no such thing as absolutely no liquid present; the inlet buffer tank serves to remove liquid and provide buffering. If liquid enters the reciprocating compressor, you can probably guess what will happen
A buffer tank must be used; although it is pure new hydrogen, it is necessary to ensure the proper operation of the compressor in cases where there is no guarantee of complete absence of liquid. Moreover, this can also be considered for the future: for diesel hydrogenation, the purity of the new hydrogen does not need to be very high; therefore, it is possible to use other sources of hydrogen, such as reformed hydrogen.
Based on the configuration of my system, it is considered unnecessary to install a buffer tank, as the fresh hydrogen in my system comes from the PSA used for hydrogen production
Saving two buffer tanks at night won’t save much, but it is necessary to assess how much the safety level will increase and what benefits it will bring to the process operations
I feel that even if we consider new hydrogen sources and the samples pass the testing and analysis, safety issues related to compressors are not something to take lightly. Moreover, as mentioned by the person upstairs, a buffer tank doesn’t help that much. We already have a sufficient dehydration and drying system before installing the new hydrogen compressor, yet we still decide to use a buffer tank~
