NITROUSE OXIDE IN AIR SEPARATIONS UNITS

Abstract

In a number of branches of industry the products of air separation are required more pure than usually. By their manufacture with the help cryogenic air separation units it is necessary to take into account conduct and an opportunity of accumulation nitrous oxide (N2O) in an adsorber, the basic heat exchanger and rectifications column. In tonnage plants N2O may to accumulate also in the units which concentrating such gases as Kr and Xe. The analysis of a nitrous oxides problem in the application to processes and elements of cryogenic air separation unit are madding in present article. It is shown and proved that the most effective way of removal N2O from products of air separation - catalytic irreversible decomposition of nitrous oxide for N2 and O2. Characteristics of catalytic transformations of N2O on palladiums catalyst, confirming an opportunity of effective decomposition of nitrous oxide are considered.
