Abstract
An arrangement of downcomers oriented at a 45-degree angle to a support that is either a wall within a divided wall column or a support beam that allows for reduced spacing of from 0.3 to 0.76 m spacing between trays within a distillation column. The advantages include the use of a single support beam to support two trays as well as more efficient operation and allowing for columns having diameters from 0.9 to 15.2 meters.
