RMS Windows-based software program allows users to quickly and easily design safety systems that assess a runaway chemical reaction and to determine the best and safest relief-venting method. Design of emergency venting requirements for vapor, gassy and hybrid systems can be made based on the Design Institute for Emergency Relief Systems (DIERS) two-phase flow methodology and its extensions. Other features include a user-friendly interface, benchmarking against actual data and the ability to perform sensitivity analyses. Fauske & Assoc. 16 W070 83rd St. Burr Ridge, IL, 60527
