摘要

The first article in this series (p. 20, Jan./Feb. 2007) discussed best practices for Dry Gas Seal (DGS) selection and design. This article will cover: Seal gas- conditioning Seal gas control Primary vent systems The source of seal gas may be the compressor discharge, an intermediate pressure point, or an external process or inert gas, or the compressor discharge. For the majority of applications, the seal Gas Conditioning Unit (GCU) will consist only of filtration (5 microns absolute) and moisture-removal equipment. The best practice is to use dual coalescing filters and automatic drainers with high level alarms. However, two special situations may require additional gas conditioning.
