Abstract
The present invention is a single vessel apparatus for separating at least a first component from a second component of a process stream. The apparatus has a vertically-elongated vessel which contains a plurality of vertically spaced apart distillation contactors for vapor and liquid distillation and an adsorbent-retaining volume defined at least in part by a solids-impermeable member located above the contactors for passing a fluid into the retaining volume. The apparatus also contains a mechanism for adding adsorbent above the solids-impermeable member and a mechanism for withdrawing adsorbent particles from the retaining volume to contact the fluid with adsorbent particles and to provide at least intermittent downward gravity flow of adsorbent particles through the retaining volume and to selectively adsorb a portion of the fluid. The apparatus further contains a regenerator for desorbing fluids from adsorbent particles which is in communication with the mechanism for adding adsorbent above the solids-impermeable member and the means for withdrawing adsorbent particles from the adsorbent-retaining volume. The fluids are desorbed in the regenerator by passing a regenerant into an…
