PROCESS FOR THE SEPARATION OF CO2 FROM A GASEOUS FEED STREAM
摘要
<p>The invention provides a process for the separation of CO2 from a gaseous feed stream, comprising the subsequent steps of: a) cooling a porous body in the form of a fixed bed (101,102,103) to a temperature below the sublimation temperature of CO2 to obtain a cold body; b) contacting a gaseous feed stream (120) comprising CO2 and one or more other gaseous compounds with the surface of the cold body to obtain a body comprising solid CO2 and a CO2-depleted effluent gas (124); and c) removing the solid CO2 by exposing the porous body comprising solid CO2 to a fluid CO2 stream (130) having a temperature above the sublimation temperature of CO2 whereby fluid CO2 (136) and a warm porous body are obtained.</p>
