Filter Assembly Developed for a High Integrity Container off-Gas Vent System

摘要

The development of a filter system to be used in disposal of EPICOR II prefilter demineralizers is described. The system was developed to permit passage of gas quantities greatly in excess of those generated in the prefilters. The filter also prevents ingress or egress of liquid or solids for the worst case conditions of potential use. The heart of the system is a polyethylene filter element of 1 micron pore size. The hydrophobic nature of polyethylene permits gas flow at low driving pressures while restricting liquid flow at relatively high driving pressure. (ERA citation 10:019983)
