摘要： A solid desiccant cooling system and method of operating a solid desiccant cooling cycle is provided comprising a desiccant support structure for cyclic movement of solid desiccant between a first location where a solid desiccant contacts a source of air to be dehumidified and a second location with a solid desiccant is regenerated. A heat exchange arrangement is provided preferably at the first location. The heat exchange arrangement provides a heat exchange or thermal engagement of a heat exchange fluid e.g. water, with the desiccant containing tubes. The proposed method and apparatus cools the desiccant while dehumidification of air is conducted. Preferably, the heat exchange fluid is provided to the desiccant support structure at a position at or adjacent its longitudinal axis, to flow radially therefrom.

摘要： An adsorption process for xenon recovery from a cryogenic liquid or gas stream is described wherein a bed of adsorbent is contacted with the aforementioned xenon containing liquid or gas stream and adsorbs the xenon selectively from this fluid stream. The adsorption bed is operated to at least near full breakthrough with xenon to enable a deep rejection of other stream components, prior to regeneration using the temperature swing method. Operating the adsorption bed to near full breakthrough with xenon, prior to regeneration, enables production of a high purity product from the adsorption bed and further enables oxygen to be used safely as a purge gas, even in cases where hydrocarbons are co-present in the feed stream.

摘要： The invention relates to a process for the regeneration of an adsorber. For the regeneration a liquid stream (S2) comprising at least one alkane is converted from liquid phase into gaseous phase. Then the adsorber is regenerated and heated by contact with gaseous stream (S2) up to 230 to 270° C. Subsequently, the adsorber is cooled first by contact with gaseous stream (S2) to a temperature of 90 to 150° C. followed by cooling with liquid stream (S2) to a temperature below 80° C. The outflow of the adsorber (S2*) during the cooling with gaseous stream (S2) and optionally the outflow of the adsorber (S2*) during cooling with liquid stream (S2) is recycled in at least one of these steps.
