Method and apparatus for removal of oil from utility gas stream

摘要

The present application is directed to a method and system for preparing gaseous utility streams from gaseous process streams, particularly, removing oil contamination from such streams prior to use in a dry gas seal. The methods and systems may include at least one kinetic swing adsorption process including pressure swing adsorption, temperature swing adsorption, calcination, and inert purge processes to treat gaseous streams for use in dry gas seals of rotating equipment such as compressors, turbines and pumps and other utilities. The adsorbent materials used include a high surface area solid structured microporous and mesoporous materials.

主权项

1. A method of treating a gaseous feed stream, comprising:
providing a gaseous feed stream having a volume of oil therein; treating a portion of the gaseous feed stream using a selective component removal system having at least one swing adsorption process unit to form a utility stream for use in a utility component, wherein the at least one swing adsorption unit includes a structured adsorbent bed comprising a high surface area solid and configured to remove at least a portion of the volume of oil and the portion of the gaseous feed stream is at a pressure from at least about 100 bar to at least about 500 bar; regenerating the swing adsorption process unit in a calcination process; feeding the utility stream into the utility component, wherein the utility stream is compatible with the utility component and wherein the utility stream is a dry seal gas; and utilizing the utility stream in the utility component.
