Abstract

A method of mitigating the consequences of a vapor cloud explosion resulting from an accidental release of a flammable gas in an open area, the method comprising: defining a hazard area in which an accidental release of a flammable gas may occur; receiving (300, 305 ) a signal from a detector device capable of detecting the presence of a flammable gas in a hazardous area, upon receipt of a signal indicative of the presence of a flammable gas in a hazardous area, generating (309) a flame acceleration inhibitor as The release activates the control signal at a rate determined as a function of the volume in the hazardous area.

Description

technical field

[0001] The present invention relates to a method of mitigating the consequences of unconfined or partially confining vapor cloud explosions by suppression. Background technique

[0002] A particular hazard in petrochemical plants and refineries is the accidental release of large quantities of flammable materials which lead to the formation of flammable clouds within the facility. Historical evidence has shown that ignition of such clouds can lead to devastating explosions and destruction of equipment. Such accidents are commonly named "Vapor Cloud Explosion" (VCE) or "Unconfined Vapor Cloud Explosion" and referred to as "VCE".

[0003] Flame suppression refers to the weakening of a flame, ie, the reduction of the rate of the overall exothermic reaction in the flame. Depending on the flow field in which the flame exists, this weakening may or may not result in extinguishment.

[0004] Flame suppression is distinct from extinguishing, flame extinction, or fl...
