Abstract
A device and process for removing vapors from a gas is disclosed. A tower is provided. Sub-cooled pellets are distributed by the solids distributor across a horizontal cross-section of the tower. A process gas, comprising a product vapor, passes through the gas inlet. The product vapor and the sub-cooled pellets comprise the same material. The product vapor and the sub-cooled pellets agglomerate as the product vapor desublimates onto the sub-cooled pellets, forming product pellets and a vapor-depleted gas. A crushing device, a screening device, and a solids heat exchanger are provided. A portion of the product pellets are recycled as sub-cooled pellets to the solids distributor by crushing and screening the portion of the product pellets to the size distribution of the sub-cooled pellets and cooling the portion of the product pellets to produce the sub-cooled pellets.
