Automated Adsorption Equilibrium Apparatus

摘要

The U.S. Army Edgewood Research, Development and Engineering Center is Currentlymeasuring adsorption phase equilibrium data for a variety of chemical warfare agents and their surrogates on a variety of adsorbent materials to correlate physical properties to filtration/separation efficiencies of each vapor on each adsorbent. Adsorption phase equilibrium data are required to evaluate any adsorption-based gas separation process. This report describes the apparatus developed in-house to measure adsorption phase equilibrium data with emphasis on the automated data acquisition devices that allow the tedious intervention. Preliminary results confirm that the results obtained using the new automated isotherms measurement system compare favorably with data measured in earlier studies using manually-controlled systems.
