1. “ BIOGAS TO POWER ” Using Biological H2S Removal “ Bioskrubber ” TM System And Gas Engines

2. INDEX  BIOGAS TO POWER …WHY?  BIOGAS APPLICATION SHIFT -“HEAT TO POWER”..WHY?  TARGET DISTILLERIES THAT WILL BENEFIT.  ABOUT “Bioskrubber” TM PROCESS  “ Bioskrubber ” TM ADVANTAGES  SERVICES FROM INNOVATIVE  REFERENCE PLANTS

3. “ BIOGAS TO POWER ”……….WHY?  Power is in short supply. 78,000MW planned in 11 th 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.

4. “ 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.

5. 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  H 2 S 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.

6. 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

7. BIOSKRUBBER TM Biological H 2 S Removal System

8. TYPICAL PROCESS FLOW DIAGRAM BIOSKRUBBER TM + Power

9. Bioskrubber TM is a biological caustic scrubber to remove H 2 S from biogas, in which the spent caustic solution is continuously regenerated in the bioreactor. BIOSKRUBBER TM PROCESS H 2 S gas + OH - HS - liquid + H 2 O HS - + 1/2O 2 + OH - Equation No 1 Equation No 2 SoSo

10.  Clean bio-technology for H 2 S cleaning.  Low operating cost of biogas - upto 92% caustic recycled.  Successful commercially operating plants for last 8 years.  Projects using BIOSKRUBBER TM PROCESS worth 30 MW of power successfully commissioned.  Very high H 2 S removal efficiency - over 99%.  H 2 S 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 BIOSKRUBBER TM PROCESS

11. ADDITONAL BENEFITS OF H 2 S REMOVAL Impact On Surrounding air.  H 2 S 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 ?

12. SERVICES OFFERED BY INNOVATIVE  Turnkey Projects from designing to commissioning.  Supervision on operations of the plant  Financing the project on a B.O.O / B.O.O.T on a case to case basis.  First B.O.O.T project signed -

13. B.O.O.T Projects by INNOVATIVE - Typical features  On a case to case basis,Innovative will entirely fund, operate and maintain the Biogas to power project.  Project size – 1.4 MW +  Innovative will get Biogas and sell Power to the distillery for captive use or will sell power to a third party.  Gas will be free or at cost.  Transfer period of the project will vary depending on other terms and conditions.  Entire plant will be transferred free of cost on transfer.
