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. The reaction vessel contains vapor, and optionally liquid, passageways to bypass one or more packed beds, preferably catalyst beds. This permits more stable and efficient vessel operation.
