Method for removal of a foulant from a carrier gas in a single vessel using cryogenic liquids

Patent ·
OSTI ID:1568356

A method for removal of a foulant from a carrier gas is disclosed. A solids conveyance device that spans a vessel is provided, comprising an enclosed section and a filtering section. A cryogenic liquid and the carrier gas are provided to the enclosed section. The foulant condenses, dissolves, or desublimates into the cryogenic liquid, forming a cryogenic slurry and a foulant-depleted carrier gas entrained in the cryogenic slurry. The solids conveyance device advances the cryogenic slurry into the filtering section. The foulant-depleted carrier gas leaves the vessel through an upper portion of the permeable exterior wall and a warmed cryogenic liquid is removed from the cryogenic slurry through a lower portion of the permeable exterior wall, resulting in a solid foulant that is passed out of the solids outlet. In this manner, the foulant is removed from the carrier gas.
