ABSTRACT:
An improved method and apparatus for treating a gaseous medium polluted with volatile organic solvents to produce a purified gaseous medium and a separate methane-rich and combustible gas. The method involves wet-scrubbing the gaseous medium with a liquid stream in a countercurrent wet scrubber to produce a purified gaseous medium and a separate liquid stream loaded with the volatile organic solvents; channelling the liquid stream loaded with the volatile organic solvents to an anaerobic bioreactor consisting of a sealed vessel containing a biomass having methanogenic bacteria adapted to transform the volatile organic solvents into a methane-rich and combustible gas and a separate liquid stream output substantially free of the volatile organic solvents; recovering the methanerich and combustible gas by collecting the gas from the anaerobic bioreactor.
