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.
