CONSTANT INTENSIFIED ATTENTION TO MAINTENANCE OF EXPLOSION SAFETY FOR AIR SEPARATION UNITS

Abstract

The basic decisions on reliable maintenance of explosion safety for air separation unit (ASU) should be realized at their designing, development of effective monitoring systems and managements. In all complex of questions considered in article is important the operation of ASU in view of performance of some requirements of its safe work. Recommendations which necessarily should be used at designing of modern air separation units are resulted in article. The necessity of analysis of processes in operating equipment, units and manufactures of ASU near air inlet for estimation of possible emissions in an atmosphere of significant amounts of the dangerous impurity caused by occurrence of extreme situations. This conclusion confirms by situation caused the explosions of two large ASU in the countries of Southeast Asia. It is paid the attention to necessity of using additional decisions for maintenance of explosion-proof work of ASU, using zeolit blocks for clearing of the processed air containing the raised quantity of dangerous impurity.
