Method and Apparatus For Removal Of Oil From Utility Gas Stream
First Claim
1. A system for treating a gaseous feed stream, comprising:
- a selective component removal system, comprising;
a gaseous feed stream inlet configured to pass a gaseous feed stream into a swing adsorption unit having at least one structured adsorbent bed comprising a high surface area solid, wherein;
the gaseous feed stream includes a volume of oil droplets and a volume of oil vapor and has a pressure of at least about 1,000 pounds per square inch;
the at least one structured adsorbent bed is configured to remove at least a portion of the volume of oil droplets and a portion of the volume of oil vapor to provide a substantially oil-free gaseous outlet stream; and
the at least one structured adsorbent bed is regenerated in a kinetic swing adsorption process.

Abstract
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.
