Understand pulsation bottle design principles, Helmholtz frequency, and API 618 requirements
A pulsation bottle is a filter vessel that dampens pressure pulsations generated by the reciprocating compressor's intermittent gas flow.
Pulsation bottle design follows API 618 guidelines for reciprocating compressor piping and pulsation control.
It calculates Helmholtz frequency, choke tube sizing, orifice plate sizing, attenuation analysis, and HP loss estimation for pulsation bottles.
Helmholtz frequency is the natural acoustic resonant frequency of the bottle-choke tube system, which must be tuned below the compressor's pulsation frequency for effective dampening.
