Relief vent sizing and location for long tubular reactors

Abstract

The DIERS (Design Institute for Emergency Relief Systems) methodology for emergency relief evaluation is recognized as a state-of-the-art procedure for reacting systems operated in batch or semi-batch mode process vessels. By comparison, the evaluation of emergency relief requirements for tubular reactors has received little consideration. This paper addresses the questions of location and size requirements for long tubular reactors. Much of the DIERS methodology is applicable in principle, and this paper suggests where certain key details may be modified for tubular reactor considerations. This paper presents emergency relief evaluation procedures for both tempered and pure gassy reacting systems and provides example illustrations of each case.
