BioskrubberTM Process for
H2S removal
BioskrubberTM is a biological caustic scrubber to remove H
2S from biogas, in which the spent caustic
solution is continuously regenerated in the bioreactor.

ADVANTAGES of BioskrubberTM PROCESS
o Very high H2S removal efficiency - over 99%.
o No risk of fire/explosion hazard as the process does not
mix air with the gas stream.
o Production of biological sulphur as a bi product. with 85-
90% purity
o No clogging – very high plant availability.
o Partial co absorption of CO2 present in raw biogas
o Very less requirement of process water as compared to
alternate technologies
o Environmentally friendly method of H2S removal with
very low effluent generation.

ADVANTAGES BioskrubberTM PROCESS
o Very high factor of system availability- Ideal for
continuous applications like power generation at base
load condition
o No expensive catalyst and chemical required.
o Operation at ambient temperature, pressure and
process liquid pH between 8 and 8.5
o No major impact of ambient temperature variations
o Robust gas cleaning system tailor made to suit Indian
Conditions
11

Alternate Application of BiogasBioCNG-The New Frontier
Biogas Upgradation to BioCNG
oBiogas typically consists of Methane, Carbon Dioxide, Hydrogen Sulphide and Moisture
oOut of these constituents only Methane is useful constituent from energy content point of view
oThe other constituents like Carbon Dioxide, Hydrogen Sulphide, Moisture are removed through the BioskrubberTM system followed by CO2 removal system to enrich the gas from biogas to Compressed Natural Gas
Project BioCNG
oIETPL is implementing the first large scale BioCNG project in India at a distillery unit
oThe project will become functional in the next 10 months
oInnovative will provide the entire Biogas UpgradationPlant consisting of H2S cleaning and CO2 removal system
oUpgraded Biogas i.e. BioCNG will contain more than 95% Methane,CO2 less than 5% and H2S less than 5 ppm.
oThis BioCNG is proposed to be used as vehicular fuel
