The contiguous compartments have a common ceiling and floor defining a passage therebetween. Each compartment further comprises a vertical separating wall extending partially the distance from the floor to the ceiling to divide the compartment into liquid and vapor sections so that liquid in the bottom of one compartment flows into the vapor section of the compartment next below.
