G-4.8: Safe Use of Aluminum-Structured Packing for Oxygen Distillation

Abstract

Many air separation plants use aluminum sieve trays in their distillation columns. Most plants built after 1990 have used structured packing in place of trays. The low pressure drop and good mass transfer effectiveness of packing make it attractive for some air separation applications, particularly for columns operating at near-atmospheric pressure.

This publication addresses the use of aluminum-structured packing in oxygen distillation. Other materials that can be used in this service such as brass, copper, or stainless steel are not addressed.

A summary of current knowledge and industrial practices used in the safe application of aluminum-structured packing in columns for the distillation of oxygen is included.

This publication is not intended to be a mandatory standard. It is based upon the combined experimental work, operating experience, and design practices of major producers and operators of air separation plants.
