H₂S removal system

H₂S REMOVAL SYSTEM

This scrubber has 3 sections: Absorber section, Reactor section & Sulphur recovery section.

Biogas enters absorber section from bottom. The caustic wash is given from the top. H2S gets absorbed in the alkaline solution and separates it out from biogas. A demister section prevents carry over of fluid into the treated gas. The scrubbed biogas leaves the scrubber at the top.
The spent scrubber liquid is collected at the bottom of the scrubber and directed to the bioreactor. In the reactor, air is dispersed at the bottom in order to enable the biomass to convert the dissolved sulfide into elemental sulfur, thereby regenerating caustic soda. The sulfur is separated as a solid and the Sulphur slurry can be pumped into Sulphur recovery unit. The slurry can be dewatered and discharged as a cake for further use. The liquor is returned to the reactor
