Countercurrent reaction vessel
CA 2262370 A1
Abstract
A reaction vessel for processing liquid petroleum or chemical streams wherein the stream flows countercurrent to the flow of a treat gas, such as a hydrogen-containing gas, in at least one interaction zone (r1, r2, or r3). The reaction vessel contains vapor, optionally liquid, passageways (VB1-5) to bypass one or more packed beds, preferably catalyst beds (r1-3). This permits more stable and efficient vessel operation.
