摘要： A process for separating a feed gas stream into an oxygen-enriched gas stream which is used in a combustor and an oxygen-depleted gas stream. The feed gas stream is compressed, and oxygen is separated from the compressed feed gas stream using an ion transport module including an ion transport membrane having a retentate side and a permeate side. The permeate side of the ion transport membrane is purged with at least a portion of a combustion product gas stream obtained from the combustion in the combustor of the gas stream exiting the permeate side of the ion transport module.

摘要： A process for removing oxygen from a feed stream to obtain an oxygen-depleted product stream by applying the feed stream to at least one separator including a feed zone and a permeate zone separated by a solid electrolyte mixed conductor membrane, and driving a first portion of entrained oxygen in the feed stream from the feed zone to the permeate zone via the mixed conductor membrane by applying at least one of a purge stream and a negative pressure to the permeate zone to establish a lower partial pressure of oxygen in that zone. Oxygen-depleted retentate is withdrawn as a product stream.

摘要： A process is provided for the improved removal of nicotine from tobacco. An essentially nicotine-free solvent in the supercritical or liquid state is fed into a first end of an extraction flow system containing tobacco and a nicotine-rich solvent is discharged from a second end of the extraction flow system. Periodically a portion of extracted tobacco is discharged from the first end of the extraction system while simultaneously a portion of an unextracted tobacco is charged to the second end of the extraction system. Nicotine is then entrapped in an entrapment material or otherwise removed from the solvent and solvent is recycled through the extraction flow system. Various materials are provided as entrapment materials. Among the entrapment materials provided are aqueous solutions containing absorbent selected from various acids and salts. Among the acids and salts provided as entrapment materials are sulfuric acid, phosphoric acid, nitric acid, tartaric acid, citric acid, malic acid, lactic acid, malonic acid, succinic acid, acetic acid, glutamic acid and monopotassium citrate.

摘要： An improved method for extracting caffeine from a coffee material, preferably raw coffee solids, with an extractant comprising supercritical carbon dioxide. Caffeine is continuously absorbed from the extractant with an aqueous wash solution in an absorber. This wash solution is continuously treated by reverse osmosis to form a caffeine-containing retentate stream and a permeate stream containing dissolved solids but substantially no caffeine. The permeate stream is recycled and used as wash water in the absorber or is used to prehydrate solid coffee materials, or both. The permeate stream comprises acidic dissolved solids.
