Abstract:
1. A method of reducing pulsations associated with the a flow of fluid through a reciprocating compressor system for operating between two gas transmission lines, the method comprising: (a) Determining an amplitude or a frequency of the pulsations to be reduced in the reciprocating compressor system, the reciprocating compressor system having: and wherein each of the plurality of connecting conduits connects the reciprocating compressor to an other system element; (b) Calculating dimensions of a pulsation-reducing insert to be placed in a connecting conduit, the pulsation-reducing insert being a tube having a tube wall defining an interior passageway, an inlet and an outlet at opposite ends of the tube, and wherein the tube interior narrows from an inlet inner diameter to a narrowed throat inner diameter, and enlarges from the narrowed throat inner diameter to an outlet inner diameter; wherein the dimensions calculated include the throat inner diameter and an axial distance from the throat to the outlet end of the pulsation-reducing insert; (c) Placing the pulsation-reducing insert into a connecting conduit of the reciprocating compressor system such that the inlet end is upstream of the outlet end of the pulsation-reducing insert; and (d) Attaching the connecting conduit having the pulsation-reducing insert therein to the reciprocating compressor or one of the plurality of other system element; and (e) boring a hole through the tube wall of the insert, the hole fluidly connecting the interior of the tube to an annular space defined between the insert and the connecting conduit, such that the annular space between the insert and the connecting conduit further attenuates pulsations.
