Abstract
Abstract A packed bed gas-liquid contactor wherein the liquid distributor is positioned within and supported by the packed bed, with the portion of the packed bed above the liquid distributor being blocked by an imperforate structure and the remaining portion including non-process packing, whereby gas flows from the process packing through a limited portion of the upper part of the packed bed, defined by the non-process packing to the gas outlet. In this manner, the residence time of the gas in the upper portion of the bed is limited.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
223 words
A gas-liquid contactor apparatus, comprising: a vessel; a gas inlet in the lower portion of the vessel; a gas outlet in the upper portion of the vessel; a liquid inlet in the upper portion of the vessel; a liquid outlet in the lower portion of the vessel; a packed bed within said vessel; a plurality of liquid distributors for distributing liquid into the packed bed, said plurality of liquid distributors being supported within and solely by said packed bed, said liquid inlet introducing the liquid into the liquid distributors, said packed bed including a lower portion below the liquid distributors and an upper portion above the liquid distributors, said lower portion of the packed bed being comprised of process packing, said upper portion of the packed bed being comprised of an imperforate structure and non-process packing, said imperforate structure blocking a portion of the upper portion of the packed bed and being comprised of a plurality of separate imperforate columns which extend from liquid distributors upwardly to the top of the packed bed, the remaining portion of said upper portion of the packed bed being comprised of said non-process packing whereby gas flows through a limited portion of the upper portion of the packed bed defined by the non-process packing to reduce the gas residence time in the upper portion of the bed.
