“BIOGAS TO POWER”……….WHY?
Power is in short supply. 78,000MW planned in 11th Plan.
1.25 lac villages and 56 % of household are non electrified-
Power is in big deficit.
Rural, decentralized and renewable power -A Priority.
Enactment of Electricity Act 2003 and Renewable policy
2005 in place.
Process industries need high quality and uninterrupted
power.
Any expansion /New downstream projects will require
additional, quality power.
Power generation/Cogeneration is becoming an important
revenue stream.
“BIOGAS TO POWER”……….WHY?
Successful reference plants available –reduced risk.
Elemental Sulphur as a high value biproduct from
Bioskrubber process , an added advantage.
CDM benefits – Generate more power, get more benefit
Therefore generating additional power from biogas now
makes good business sense.
Biogas application from “ Heat to Power ” A High Value Shift
Biogas already available with many distilleries.
Current utilization of biogas - mostly as heat value.
Biogas fired Gas Engines - for high value shift.
1 m3 of gas fired in engine can give 2 units of power .
High efficiency - Electrical 40.8%+17.5%+22.9% =81.2%
System configuration -Biogas+Bioskrubber+Gas engines
H2S in the biogas must be removed for gas engine
application.
Typical H2S in biogas from distilleries is 3% to 5%.Should be
brought down to 250 ppm.
TARGET DISTILLERIES
Biogas to Power project will benefit all Distilleries such as:
Those having high power consumption from the grid.
Those having other plants/offices in Group companies
buying high and expensive power from the grid.
Those attached to sugar factory having cogen unit and
selling power to the grid.
Those wanting to sell power to a Third party

BioskrubberTM is a biological caustic scrubber to remove H2S from biogas, in which the spent caustic solution is continuously regenerated in the bioreactor.
BIOSKRUBBERTM PROCESS
H2Sgas + OH- HS-liquid + H2O
HS- + 1/2O2 + OH-
Equation No 1
Equation No 2
So
Clean bio-technology for H2S cleaning.
Low operating cost of biogas - upto 92% caustic recycled.
Successful commercially operating plants for last 8 years.
Projects using BIOSKRUBBERTM PROCESS worth 30 MW of
power successfully commissioned.
Very high H2S removal efficiency - over 99%.
H2S reduction to less than 250 ppm guaranteed.
No expensive catalyst and chemical required.
Operation at ambient temperature, pressure and PH between 8
and 8.5 .
Elemental SULFUR as bi-product with 90% purity.
ADVANTAGES BIOSKRUBBERTM PROCESS
ADDITONAL BENEFITS OF H2S REMOVAL
Impact On Surrounding air.
H2S is Highly Corrosive – Can damage other equipments and expensive instruments in the vicinity.
Health Hazard and odour nuisance.
Pollution Board Norms - Sulphur emission “Cap” in kgs/day - Today laws are not stringent,
Tomorrow ?
SERVICES OFFERED BY INNOVATIVE
