Overview

Strict enforcement of environmental pollution standards has had a dramatic impact on tank storage of flammable liquids. Rather than expelling vapors into the atmosphere, the trend has been toward the connecting or manifolding of multiple tanks through common piping to a central processing unit. These closed piping systems, or vapor recovery / collection systems, have created unique flammable vapor safety hazards. The piping runs in these vapor recovery systems tend to be longer and more complex. Potential sources of ignition may actually be present within the vapor collection system itself. An ignition within a piping system can result in a flame front that accelerates very rapidly and generates extremely high pressures. A low speed, low pressure confined deflagration can readily transition into a high speed, high pressure confined deflagration and then to a detonation, which is a flame front moving at the speed of sound in the vapor/air mixture. “DETONATION” arresters are specifically designed to stop and extinguish detonations, confined deflagrations and unconfined deflagrations. The limitations that are placed on the location of end-of-line and vent-line / in-line flame arresters with respect to the ignition source do not apply to detonation arresters.
