Flame and Detonation Arrestor Design

Source: NAO
The selection, design, construction and testing of reliable deflagration and detonation arrestors must be based on worst-case analyses of all operating parameters.
The selection, design, construction and testing of reliable deflagration and detonation arrestors must be based on worst-case analyses of all operating parameters. Full-scale tests, matching actual plant layouts, should then be conducted for the most dangerous range of flammable gas concentrations, pressures and temperatures.

An informative six page color reprint of a Petrosafe Conference paper (Report RP93-7) includes valuable information on how peculiarities of detonation waves affect braking of sonic detonations and effective quenching of subsonic deflagrations. Colorful illustrations of various full-scale tests for butadiene, ethylene, ammonia flares, etc. essential criteria for dependable low-pressure drop arrestors, designed to prevent explosions and flashback in process equipment, as well as in transportation and storage of gasoline and other flammable materials.

Fourteen references to associated reprints are included; and all are available to plant operating and maintenance personnel upon request, including a report by W.B. Howard in Chemical Engineering Progress, "Use Precaution in the Selection, Installation and Operation of Flame Arrestors" (RP92-1).
