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.

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; andutilizing the utility stream in the utility component. 2. The method of claim 1, wherein the gaseous feed stream contains at least one hydrocarbon component. 3. The method of claim 1, wherein the gaseous feed stream is a compressor discharge stream. 4. The method of claim 1, wherein the gaseous feed stream is a pressurized process stream. 5. The method of claim 1, wherein the gaseous feed stream is at a pressure above the critical point of the gaseous feed stream. 6. The method of claim 4, wherein the gaseous feed stream is at a pressure of from at least about 200 bar to at least about 320 bar. 7. The method of claim 1, wherein the utility component is selected from the group consisting of a compressor, a compressor string, a turbo-expander compressor, a turbo-expander generator, a pump, a fired steam boiler, a fired process heater, a gas engine, a hermetically sealed direct-drive electric motor, turbomachinery equipped with magnetic bearings, and a gas turbine. 8. The method of claim 7, wherein the first utility stream is utilized as a dry seal gas for at least one of a dry gas seal, a labyrinth seal, and a mechanical seal in the utility component. 9. The method of claim 8, wherein the at least one swing adsorption process unit is selected from the group of units consisting of a pressure swing adsorption (PSA) unit, a thermal swing adsorption (TSA) unit, a partial pressure swing or displacement purge adsorption (PPSA) unit, a rapid cycle thermal swing adsorption (RCTSA) unit, a rapid cycle pressure swing adsorption (RCPSA) unit, a rapid cycle partial pressure swing or displacement purge adsorption (RCPPSA) unit, a compact PSA, a compact TSA, a compact PPSA, and any combination thereof. 10. The method of claim 9, wherein the selective component removal system (SCRS) further comprises at least one of an absorption unit, a membrane separation unit, a molecular sieve, a distillation tower, and a glycol contactor. 11. The method of claim 1, wherein the gaseous feed stream comprises from about 60 mol % to about 90 mol % methane. 12. The method of claim 1, wherein the gaseous feed stream is a sour process gas stream and the portion of the gaseous feed stream is a slip stream from the sour process gas stream. 13. The method of claim 1, wherein the utilizing the utility stream in the utility component reduces condensation across a seal face of the utility component.
