<p>A single pass, shell and tube reactor which is designed for downflow of reactant fluid in tubes containing contact material is improved to allow more than one downflow pass of fluid through the tubes by providing upper and lower vertically aligned partition members to divide the upper and lower tube end chambers into isolated compartments and by using an empty tube to allow upflow communication between adjacent compartments. In a two compartment configuration, the upper and lower tube end chambers are each partitioned in half, but the lower partition member has a screened port to allow fluid from the first compartment to reach, and move upwardly through, an empty tube(s) in the second compartment which is isolated from the other tubes in the second compartment at its bottom end but not at its top end.</p> |
