The Design Institute for Emergency Relief Systems (DIERS) Users Group awarded Arthur D. Little, Inc., a contract to provide the next generation computer program for emergency relief system and effluent handling designs. The new computer program, SuperChems for DIERS, is a dynamic simulator, capable of performing emergency relief system and effluent handling designs for complex geometries and multiphase reaction systems. In addition, SuperChems for DIERS is an equation-of-state based program which provides several benefits over existing non-equation-of-state based methods for systems involving supercritical reactions like polymerizations of butadiene and acrylonitrile, solution effects such as HCl/Water, and a priori determination of phase splitting. This new computer program allows the user to dynamically simulate several common configurations for vent containment design. For example, the user is able to simulate a vessel discharging a two-phase mixture into a quench/vent where the catch/vent tank will vent to a stack or a scrubber. Unit operations available include separators (horizontal and vertical), cyclones, etc. The impact of back pressure and continuing reaction in the vent containment system is accounted for in the dynamic simulations.
