Description

We have developed and evaluated a carbon filter to remove dimethyl sulfoxide (DMSO) vapor from the exhaust of the W79 HE (high explosive) Dissolution Workstation. A series of laboratory tests were conducted on eight different carbon samples to establish the vapor breakthrough curves and to select the best sample. Empirical equations were developed to predict the breakthrough curve for various air flows and bed thickness, These equations were used to design the filter cartridge. The filter consists of a cylindrical cartridge 12 inches high and 6 and 10 inches inside and outside diameter and has a pressure drop of 0.8 ... continued below

A series of laboratory tests were conducted on eight different carbon samples to establish the vapor breakthrough curves and to select the best sample. Empirical equations were developed to predict the breakthrough curve for various air flows and bed thickness, These equations were used to design the filter cartridge. The filter consists of a cylindrical cartridge 12 inches high and 6 and 10 inches inside and outside diameter and has a pressure drop of 0.8 inches of water at 50 cfm. Experiments and computations verified the efficiency of the filter cartridge is greater than 99% at 35 cfm, and the carbon filter can process 60 HE assemblies while maintaining greater than 90% efficiency before the carbon must be replaced.
