Evaluation of the Lewisite Protection Provided by the Oquirrh Mountain Facility (OMF) Process Filter
Abstract
The Program Manager, Elimination of Chemical Weapons, tasked the U.S. Army Edgewood Chemical Biological Center (ECBC), Chemical Biological Filtration Team, to estimate the protection time afforded by the Oquirrh Mountain Facility's (OMF) process filter for lewisite. To accomplish this, it was necessary to construct a test apparatus to measure lewisite breakthrough data and develop a defensible methodology to convert these data into a process filter performance estimate. This report provides all the details of the experimental system design, data measured, and analysis used to generate the process filter protection time. In addition, data were measured for two additional adsorbents: (1) 12 x 30 mesh ASZM-TEDA carbon to establish protection times for a C2 canister, and (2) 6 x 16 mesh ASZM-TEDA carbon to determine if using this material would be more suitable than using the Vapure 612 in the process filter. The process filter using the Vapure 612 carbon currently installed at the OMF site will prevent lewisite from penetrating the first 3-foot bed section for at least 5 years. This estimate assumes the worst operating conditions possible. There is a potential for false positives due primarily to the fact that the Vapure 612 will not retain HCl. The authors recommend changing one filter bank of Vapure 612 carbon with the Calgon's ASZM-TEDA carbon to prevent this.
