I am working in Green Hydrogen sector. Wanted to learn requirement of Buffer vessel upstream of Reciprocating compressor if we are generating H2 at 8 barg from Electroylzer. If not like conventional oil ang gas knock out drum is sufficient.

Determine the mechanical requirements from the compressor vendor. Consider also the process requirements for each scenario. I don't think there is any rule of thumb to use as a shortcut to custom calcs for your situation.

Check cold start conditions - you shall guarantee that upstream pipe is free of water. The same shall be valid for water droplets carried out during a pressure/flowrate surge. The core idea is a pipe is not able to provide droplets separation and diverting.

Also consult the manufacturer depulsation requiremens/recommendations.
