摘要:
A method and apparatus for removing water from compressed air is disclosed. The method includes the steps of passing a stream of compressed air through a pressure swing adsorption (PSA) dryer. The dryer one or a pair of vessels containing a desiccant material bound into pieces, for example tubes, using a polymer binder. The PSA dryer also has a control system for controlling the flow of the compressed air and switching between drying and purging modes. In particular the vessel and desiccant material contained therein are sized to produce a dew point suppression of less than 50°C.
摘要:
A temperature swing adsorption process for the removal of a target species, such as an acid gas, from a gas mixture, such as a natural gas stream. Herein, a novel multi-step temperature swing/pressure swing adsorption is utilized to operate while maintaining very high purity levels of contaminant removal from a produc t stream. The present process is particularly effective and beneficial in removing contaminants such as C0 2 and/or H 2 S from a natural gas at relatively high adsorption pressures (e.g., at least 500 psig) to create product streams of very high purity (i.e., very low contaminant levels).
摘要:
Process for purifying one supply gas stream and one secondary feed comprising one gas stream coming from a secondary gas line, by CPSA, comprising at least two adsorbers, each adsorber following, in an offset manner, a pressure cycle comprising a gas production phase and a regeneration phase, a purified gas enriched with the principal constituent being produced at the distribution pressure P1 during the production phase, said process being characterized in that the regeneration phase comprises at least a first countercurrent decompression step and a first elution step followed by a second countercurrent decompression step and a second elution step, making it possible, during the first elution step, to remove, without recompression, a waste gas at a distribution pressure P2, and makes it possible, during the second elution step, to remove, at a distribution pressure P3, where P1 > P2 > P3, a recycle gas recycled into the multifeed gas supply.
摘要:
A pressure swing adsorption method for separating gas components includes pressurizing an adsorption bed to an adsorption pressure using a first gas component of a feed gas, the adsorption bed including an adsorbent for substantially adsorbing a second gas component of a feed gas; introducing the feed gas to the pressurized adsorption bed, wherein the first gas component of the feed gas substantially passes through the pressurized adsorption bed and the second gas component of the feed gas substantially adsorbs onto the adsorbent; and depressurizing the pressurized adsorption bed to recover at least a portion of the second gas component of the feed gas in the pressurized adsorption bed.
