Comparative study on the performance of the standardized test method for detonation flame arrestors

  • Detonation flame arresters are widely used as protection systems in industrial applications to avoid damage from incidental gas explosions, by preventing the propagation of the ongoing explosion from one section of a plant to another. Numerous processes in the chemical and petrochemical industry are taking place under non-atmospheric conditions (e.g. increased pressure and/or temperature) in order to optimize the production capabilities. The suitability of detonation flame arresters is verified and examined according to the DIN EN ISO 16852 standard, which is only based on findings from experiments under atmospheric conditions. In some instances, differing results are obtained by the different institutes using the current standardized test procedure, especially for instable detonations as well as for detonations at elevated pressures before ignition.

The primary objective of this study is to develop an improved test method for detonation flame arresters, which offers a higher reproducibility and moreover, an applicability under non-atmospheric conditions. For this aim, the project partners (PTB, BAM, Braunschweiger Flammenfilter GmbH and IBExU GmbH) jointly conduct an interlaboratory comparison on the performance of in-line flame arresters for stable and instable detonations. The experiments are performed according to the test method regulated in the DIN EN ISO 16852 standard for different pressures before ignition and for different explosion groups (IIA, IIB, IIC). The interlaboratory comparison points out potential ambiguities of the standardized test procedure that might lead to the differing results at the different institutes. Based on these experimental findings, an improved test method for detonation flame arresters will be developed, which will ensure a greater safety at process plants while handling combustible liquids and gases.zeige mehrzeige weniger
