Patent ID: 8715401

Claim:
A system for separating condensable vapors from gases to form a solid, comprising: a separation vessel having a process stream inlet, a light gas outlet, and a solids outlet separate from the light gas outlet, wherein the process stream inlet is in fluid communication with a process stream that includes condensable vapors; a bed of particles within the separation vessel, the bed of particles in fluid communication with the process stream, wherein the process stream has sufficient pressure to flow through at least a portion of the bed of particles; and an in-bed heat exchanger comprising one or more conduits at least partially submerged in the bed of particles; wherein the temperature and pressure within the bed are sufficient to desublimate at least a portion of the condensable vapors from the process stream onto the bed of particles and/or onto an exterior of the conduit of the in-bed heat exchanger so as to form a condensed solid and a separated light gas stream, wherein the light gas outlet is configured so that the separated light gas stream exits the separation vessel through the light gas outlet, wherein the solids outlet is configured so that the condensed solid exits the separation vessel through the solids outlet.
