Abstract

Cryogenic air separation distillation columns which employ structured packing can have multiple packed sections in order to accommodate incoming and outgoing liquid and vapor streams along with distributors and redistributors. Thus in general the liquid and vapor loading will vary in the different sections. To maximize the utilization of the packing it is desirable to operate each section as close to its flooding limit as possible, such as 75 - 85% of flooding velocity. There are several ways to accomplish this objective.
