Abstract:
A comprehensive and robust design approach for reciprocating compressor systems is stipulated in
the API 618 standard. In addition to the acoustic design (aiming at minimizing pulsation and shaking
forces), also the mechanical design must be validated and optimized. The optimization of the pipe support
locations is commonly done based on expert judgement. This ad-hoc approach is time-consuming and
sometimes the optimal layout is not found.
In this paper, an optimization methodology is presented, aiming to reduce the time needed for mechanical
optimization and to enhance the confidence that the optimal solution is found. It is the authors opinion
that these optimization techniques provide a valuable extension of the toolbox of the pulsation and
vibration consultant, saving engineering time and resulting in a more robust system.
