SIMPLIFIED METHODS FOR VENT DISPOSAL SYSTEM SIZING FOR RUNAWAY CHEMICAL REACTIONS: EC AWARD PROJECT GUIDANCE FOR SMEs

摘要

The EC AWARD project had an objective to produce a design methodology for disposal systems to protect the environment from pressure relief of runaway chemical reactions. One required output was simplified guidance suitable for SMEs. The needs of SMEs are discussed. Simplified sizing methods, which are documented in the HSE Workbook for Chemical Reactor Relief System Sizing (Etchells, 1998), have been compared with large-scale experimental results from the AWARD project. Based on this limited comparison, recommendations are given for the estimation of: 1. The quantity of material vented to the disposal system. 2. The flow rate to the disposal system. 3. The pressure in the reactor (which is an input to calculating the flow rate).
