What size should the inlet and outlet buffers and separators, as well as the cooler, be for a reciprocating compressor?

What determines the size of the buffers and separators at the inlet and outlet of reciprocating compressors, as well as the size of the coolers? Are there any standard requirements?
Check if the API574 standard has any requirements.
These are not standard components; they are calculated based on the actual operating conditions. For example, in the case of a buffer tank, it is necessary to know the diameter of the piston and piston rod, the stroke, the rotational speed, the adiabatic coefficient, the suction and discharge coefficients of the compressor during operation, the volumetric efficiency, and so on; then, the dimensions are determined in accordance with the standards for pressure vessels. If it’s just a rough estimate, it can be estimated based on experience.
Requirements are specified in API618 and API11N; calculations must be carried out based on the actual conditions
