Pressure fluctuations occur in the gas in reciprocating compressor connecting lines because of their discontinuous operation. To smooth these fluctuations, pulsation dampeners are provided for each cylinder. The volume, V, of these bottles, which are generally empty, is notably derived from the maximum allowable amplitude, p, of the pressure fluctuation (residual pulsation). Furthermore, V also depends on the cylinder data, the gas and the operating mode. Under otherwise similar conditions, residual pulsation and/or bottle volume can be reduced by additional pressure losses or acoustic filters. The paper describes acoustic resonance, effects of acoustic filters, acoustic filter design, and illustrates with an example.
