摘要： A system for removing acid gases from a raw gas stream is provided. The system includes a cryogenic distillation column. The cryogenic distillation column receives a dehydrated and chilled sour gas stream, and separates the sour gas stream into an overhead gas stream comprised primarily of methane, and a bottom acid gas stream comprised primarily of carbon dioxide. The system also includes a series of co-current contactors. The co-current contactors may be placed in series to receive the bottom acid gas stream and recapture any entrained methane gas. Alternatively or in addition, the co-current contactors may be placed in series to receive the overhead gas stream, and sweeten it using a reflux liquid such as methane. In this instance, the sweetened gas is optionally liquefied and delivered for commercial sale, or is used as fuel gas on-site.

摘要： In the transportation and processing of natural gas liquid nitrogen and liquid carbon dioxide is used in a heat exchanger process to liquefy natural gas supplied by a field site. The liquefied natural gas is transported to a regasification plant where cold energy in a part of the liquefied natural gas in an air separation device is used to produce liquid nitrogen and oxygen, natural gas. The oxygen is combusted in a power production plant, which captures the carbon dioxide produced by the combustion. This carbon dioxide is liquefied it using another part of the liquefied natural gas. The liquid nitrogen and liquid carbon dioxide is then transported to be used for further liquefaction of natural gas supplied by the field site.

摘要： A process for concentrating and recovering methane and carbon dioxide from landfill gas includes absorption of commonly occurring pollutants using a reduced amount of carbon dioxide absorbent which itself may be an in situ derived and recoverable constituent. Separated methane may be concentrated into a high heating value fuel, and a highly pure food-grade carbon dioxide product may also be recovered. Process streams may be used to provide fuel for compression and refrigeration and/or to regenerate carbon dioxide absorbent.

摘要： A method for producing power and argon is provided by providing a residual gas stream, purifying the residual gas stream in a front-end purification unit to remove carbon dioxide, thereby forming a purified residual gas stream, and introducing the purified residual gas stream to a cold box, wherein the purified residual gas stream is cooled and expanded within the cold box to produce power and then fed to a distillation column system for separation therein, thereby forming an argon-enriched stream and optionally a nitrogen-enriched stream and/or an oxygen-enriched stream, wherein the residual gas stream is sourced from a retentate stream of a cold membrane having oxygen, nitrogen, carbon dioxide, and argon.

摘要： A single compressor is used to separately compress permeate from cascaded first and second gas separation membrane-based separation units and residue from a fourth gas separation membrane-based separation unit in order to avoid too high a CO2 partial pressure in the compressed permeate. After the permeates from the first and second stages are compressed, the compressed stream is fed to a third gas separation membrane-based separation unit.

摘要： A natural-gas purification apparatus includes: a compressor; a cooling unit that liquefies and separates a part of natural-gas liquid; a heating unit; first to third carbon-dioxide separation units that separate carbon dioxide through carbon-dioxide separation membranes; a detection carbon-dioxide separation unit that further separates carbon dioxide through a carbon-dioxide separation membrane; a carbon-dioxide-flow-rate sensor that detects the amount of carbon dioxide separated by the detection carbon-dioxide separation unit; an arithmetic control device that adjusts and controls at least one of the pressure to be applied by the compressor, the cooling temperature of the cooling unit, and the heating temperature of the heat unit based on information from the carbon-dioxide-flow-rate sensor such that the amount of carbon dioxide to be separated by the detection carbon-dioxide separation unit will be higher than or equal to a prescribed amount.
