Study on Pulsations of Reciprocating Compressor Piping Systems : 3rd Report, Analysis of Pulsations in the Piping

Pressure pulsations in reciprocating pump piping systems Part 1: modelling

A distributed parameter model of pipeline transmission line behaviour is presented, based on a Galerkin method incorporating frequency-dependent friction. This is readily interfaced to an existing model of the pumping dynamics of a plunger pump to allow time-domain simulations of pipeline pressure pulsations in both suction and delivery lines. A new model for the pump inlet manifold is also pro...

Fault Diagnosis of Reciprocating Compressor Using Pressure Pulsations

The major problems encountered in a reciprocating compressor are because of the valve failure .The other problem of leakage past the piston because of the worn out piston rings has also been placed in the reciprocating compressor. Pressure pulsations generated inside the piping of a reciprocating compressor may be taken as one of the tool for diagnosing the nature of fault inside the compressor...

Study on Influence of Certain System Parameters on Pressure Pulsations of Multistage Reciprocating Compressor System

Prediction of pressure pulsation magnitude and their harmonic components for a multistage reciprocating compressor, piping and reservoir system depends on the input design and operating parameters. In the present paper, the results of the theoretical study carried out to study the effect of such parameters on pressure pulsations and their harmonics have been presented. The effect of pipe diamet...

Design Challenges for Reciprocating Compressors in Specialty Gas Services

Many software tools are used to simulate compressor performance and pressure pulsations in piping systems. Designers of reciprocating equipment rely on these tools to accurately simulate gas properties and pressure pulsations for specialty gases. Two case studies on reciprocating compressors, involving ethane and ethylene, outline the root causes and consequences of inaccurate performance and p...
