Hi,

In a slug catcher area with 100 meter length, 6 No of 34" bottles where natural gas (87%methane is separated from HC condensate) in an open area of plant should I consider a scenario for vapour cloud explosion? if I use Multi energy method what figure should I use for block ratio for a release of 100 tons/hr of natural gas. Considering explosion has happened in some natural gas pipeline in open area, should I consider VCE in open area for a high pressure natural gas?

Thanks,
