초록

Separation of one or more fluidic components from a feed fluid containing a plurality of components is accomplished by adsorbent powder entrained in a stream of fluid, such as gas, and preferably is operated as a temperature swing adsorption process using waste thermal energy from a plant.

[ We claim:] [1.]1. A process for selectively removing from a feed fluid at least one of a plurality of fluidic components present in a stream of feed fluid, the process comprising:(a) providing the stream of feed fluid at a first temperature;(b) providing unloaded selective adsorbent powder and entraining said adsorbent powder in the stream of feed fluid to provide a mixture of adsorbent powder suspended in the stream of feed fluid, said selective adsorbent powder adapted to selectively adsorb at least one of the plurality of fluidic components from the stream of feed fluid;(c) cooling the mixture of the adsorbent suspended in the stream of feed fluid to a lower second temperature whereby said selective adsorbent powder selectively adsorbs the at least one of the plurality of fluidic components from the stream of feed fluid;(d) separating the adsorbent powder from the cooled suspension of adsorbent in the stream of feed fluid to provide:(1) separated adsorbent powder having adsorbed thereon the at least one selectively adsorbed fluidic component from the stream of feed fluid, and(2) as a first fluidic product, a stream of feed fluid having selectively removed therefrom the at least one selectively adsorbed fluidic component;(e) providing a secondary fluid stream and introducing the separated adsorbent powder of (d)(1) into the secondary fluid stream;(f) heating the separated adsorbent powder in the secondary fluid stream to a third temperature higher than said second temperature to desorb and release from the adsorbent powder the at least one selectively adsorbed fluidic component to provide:(1) unloaded adsorbent powder, and(2) as a second fluidic product, a stream of the secondary fluid containing the at least one selectively adsorbed/desorbed fluidic component from the feed fluid stream; and(g) separating the unloaded adsorbent powder of (f)(1) from the second fluidic product of (f)(2).
