Title: Extra combustible gas added to reduce detonation risk - in gas mixt. before absorption removal of combustible gases
Inventor: ABIDIN IRAWAN ING GRAD
IPC: B01D53/02
Filed: 1980-02-15
Abstract: Before the combustible components are adsorptively removed from gas mixts. which run the risk of dtonating, the mixt. is made inert by adding a further combustible gas, making the total combustible gas concn. at least 50% above the upper explosive limit. The added gas should be unadsorbed or adsorbed only to a small extent. One possible combination is methane addition with active carbon as the adsorber. Used as a safety measure, e.g. for discharged vapour mixts. from oil refineries, as an alternative to adding enough air to thin the mixt. below the lower explosive limit. The gas volumes for handling are thus considerably reduced.
