摘要： A system for removing acid gases from a raw gas stream the system includes a cryogenic distillation tower. The tower receives and separates the raw gas stream into an overhead methane stream and a bottom liquefied acid gas stream. Refrigeration equipment downstream of the cryogenic distillation tower cools the overhead methane stream and returns a portion of the overhead methane stream to the cryogenic distillation tower as liquid reflux. The system also may include a first molecular sieve bed upstream of the distillation tower and a second molecular sieve bed downstream of the distillation tower. The first molecular sieve bed adsorbs water while the second molecular sieve bed adsorbs additional acid gases from the cooled overhead methane stream.

摘要： The air distillation unit (2) has a low-pressure column (11C) which operates clearly above atmospheric pressure. The waste nitrogen coming from this column serves to purge, under low pressure, the air purification adsorbers 10A, 10B) in order to desorb at them of the contaminants (water and CO2), then is mixed with the impure nitrogen stream sent directly to the nitrogen compressor (14) which feeds the combustion chamber (8) of the gas turbine (1). At the start of regeneration, each adsorber is decompressed down to atmospheric pressure, then brought back up to the low pressure by means of impure nitrogen.

摘要： A system and method for recovering high-quality biomethane (RNG) from biogas sources is provided. The gas stream is compressed and liquids are separated from the gas stream at elevated pressure and reduced temperature. The compressing is performed using a plurality of compressors operating in parallel with common control set points. The system and method improve upon conventional practices and yield a biomethane product which meets strict gas pipeline quality specifications. Additionally, the system and method are an improvement to the overall methane recovery efficiency for biogas processing facilities.

摘要： A method and apparatus for the production of air gases by the cryogenic separation of air with front end purification and air compression can include using an available compressed dry gas such as nitrogen, oxygen, stored purified air, or synthetic air to repressurize the adsorber without diverting any of the purified air just exiting the currently on-line adsorber or changing the flow rate of the main air compressor or air sent to the cold box. This enables the main air compressor (MAC) to operate at a relatively constant flow rate while also sending a relatively constant air flow to the cold box during this repressurization step, thereby reducing the risks of process upsets and minimizing capital expenditures related to the MAC and other warm-end equipments.

摘要： A system and method for recovering high-quality biomethane (RNG) from biogas sources are provided. The system and method improve upon conventional practices and yield a biomethane product which meets strict gas pipeline quality specifications. An online sample is captured of a gas stream in near real-time at a pressure swing adsorption vessel, and the online sample is analyzed to detect the presence of one or more targeted products such as CH4, CO2 or N2. The system and method are an improvement to the overall methane recovery efficiency for biogas processing facilities, specifically with regard to PSA control to prevent over or under saturation of the PSA media.
