“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
