Stepless Capacity Control Systems for Reciprocating Compressors

This paper was presented at 9º Fórum de Turbomáquinas Petrobras. Steve ChaykoskyManager, Valve Engineering Joel SanfordSr. Project Engineer SUMMARY This paper introduces two stepless capacity control systems for reciprocating compressors: Dresser-Rand’s Infinite Step Control (ISC) system and Hydraulic Variable Volume Clearance Pocket (HVVCP). Case studies describe the relative advantages of each unloader system and how […]

Unique Compressor Design Allows Efficient Operation Over Wide Range

Compressor characteristics aligned with the client’s needs; emissions regulations addressed with electric motor driver. For 60 years, natural gas pipeline companies relied primarily on reciprocating compressors to move gas along the line. Most of this compression was in the form of integral gas engine compressors, which combined the power cylinders and the compressor cylinders on […]
