Abstract
Pressure pulsations are an intrinsic feature of reciprocating compressor systems, that may lead to various issues. The API 618 standard is the most relevant guideline for pulsation and vibration control during the design stage. However, the main focus of API 618 is on pulsation effects in the field piping, and less on the pulsations close to the compressor. Recent experiences indicate that these Cylinder Gas Passage (CGP) pulsations can lead to serious consequences, such as limited lifetime of compressor valves, high-frequency vibrations of the compressor manifold, reduced compressor performances and failure of compressor parts. To enhance awareness and to formulate best practices to identify and control CGP pulsations, a pre-competitive research project was assigned by EFRC’s R&D group. The investigation included literature study, interviews with experts from industry and review of analysis and measurement techniques. A systematic discussion and demonstration of harmful effects is presented, along with best practices for numerical evaluation and field measurements. Furthermore screening techniques that do not require detailed simulation tools are presented, enabling a risk assessment very early in the design. The benefits and limitations of the common control techniques are discussed, along with potential benefits of more advanced control techniques.
