Abstract
Methods and systems for regenerating a purification bed take advantage of inert gas pressure, such as, for example, supplied by a pipeline. The inert gas (102) is provided at a first pressure and combined with a recycle composition (116) from the vessel (110, 110a) containing the material being regenerated. These streams form a regeneration fluid composition (114) at a second pressure less than the inert gas pressure, which is then routed to the vessel to regenerate the purification bed. A jet compressor (108) may be used for the combining of the inert gas and recycle streams. The recycled composition allows reduction in inert gas usage, while a portion is flared or otherwise disposed of.
Claims22
A method of regenerating a purification bed contained in a vessel, the method using an open loop cycle wherein a portion of an effluent from the vessel is recycled as a recycle composition and the remainder is vented, the method comprising:
- a) providing an inert gas at a first pressure P1;
- b) combining the inert gas with a recycle composition from the vessel to form a regeneration composition at a second pressure P2, the recycle composition at a third pressure P3 such that P1>P2>P3;
- and
- c) routing the regeneration composition to the vessel to regenerate the purification bed.
A system for regenerating a purification bed contained in a vessel which uses an open loop cycle, wherein a portion of vessel effluent is recycled as a recycle composition, and the remainder is vented, the system comprising:
- a) a supply of an inert gas at a first pressure P1;
- b) the supply of inert gas fluidly connected via a conduit to a jet compressor for combining the inert gas with a recycle composition flowing through a first conduit fluidly connecting the jet compressor and a vessel containing a purification bed being regenerated, the jet compressor forming a regeneration composition at a second pressure P2, the recycle composition at a third pressure P3 such that P1>P2>P3;
- c) a second conduit fluidly connecting the jet compressor with the vessel for routing the regeneration composition to the vessel to regenerate the purification bed.
