BioRenewables EPC TURNKEY PROJECTS: BIOGAS TO POWER: Biogas genset based projects for conversion of waste to bio-power BIOGAS TO BIOCNG: Projects for conversion of waste to CNG grade fuel

Highlights of BioRenewable Projects

Beneficiaries Feedstock Agricultural Waste Animal Waste Industrial Waste (distillery/palm oil/starch/sugar/paper/food processing) Sewage Treatment Plants (STP) Municipal Solid Waste (MSW) Beneficiaries Farmers Gas Producers Gas Distribution Companies Industries Producing Organic Effluents Nations

Biogas to Power Clean electricity from waste More profitable option than firing biogas in boilers 33 large-scale projects successfully commissioned by IETL across 16 different industries

Biogas to Power- Typical Plant Scheme Biogas Generation from organic solids/effluents. Biogas Cleaning System for H2S removal (BIOSKRUBBERTM) Biogas Fired Engine i.e. Biogas Genset. Steam Generator running on Engine Exhaust. Plate Heat Exchanger connected to Engine Jacket to recover jacket water heat.

Biogas to Power- Case Study 140 MLD capacity STP at Rithala, New Delhi being constructed by M/S. Degremont India Ltd.; an Indian business unit of a French major in the STP space First biogas genset-based power generation plant in the Sewage Treatment sector in India STP Completely self sufficient in terms of electrical power requirements Operating successfully on BioskrubberTM since 2002. Operations and Maintenance Contract being carried out by us for the entire period since the commissioning STP Capacity Biogas Generation H2S % Biological Sulfur Removed BioPower 140 MLD 20160 m3/day 1% 288 Kgs./day 2 MW

Biogas to BioCNG Highest return for every m3 of biogas Replacement of fossil fuel e.g diesel/petrol/CNG/LPG Pioneering projects - Inspiration for others Environmentally cleanest fuel- better than natural gas Renewable source of energy.

Biogas to BioCNG- Case Study IETL has designed, constructed and commissioned the first large scale Biogas to BioCNG upgradation project for Spectrum Renewable Energy at Warana in India on pressmud and distillery biogas. IETL has provided the entire Biogas Upgradation Plant consisting of H2S cleaning and CO2 removal system Upgraded Biogas i.e. BioCNG contains more than 95% Methane, H2S less than 5 ppm and moisture at -40o C DP This BioCNG will be used as vehicular fuel/LPG replacement The project status: Successfully commissioned

SulfabactTM- Biological Sulfur New formulation by IETL for development of activated biological sulfur as vital “S” nutrient additive under the brand name SulfaBactTM (Pat pending) Advantages of SulfaBactTM: Timely availability of needed sulfur nutrient to plants Activity of soil microorganisms enhanced on soil application due to optimum pH No leaching out by rains, flooding as in sulfate fertilizers Sulfur dispersion in soil very high and conversion very efficient due to colloidal size of sulfur Appropriate environment for microbes – slow release All other pH dependant nutrients of soil slowly unlocked and made available to plants.

Additional Services Offered OiI & Gas Processing Projects: IETL has the capability to provide EPC services for small oil and natural gas processing projects. Our competitive advantage lies in the ability to offer our customers support across all phases of an asset, from conceptual design, technology, through construction, operations, training, and where appropriate, co-investment. Engineered Skids: H2S Removal Skids BioskrubberTM biochemical system with recovery of high commercial value biological sulfur SulfabactTM Absorbent-based systems to reduce the H2S to ppb level Membrane-based gas cleaning skids to remove CO2 and H2S from gas streams.

Additional Services Metering skids IETL provides innovative and integrated fiscal/custody transfer metering skids for oil & gas metering. IETL can build quality-engineered, pre-assembled and pre-tested modular systems fully integrated into a skid-mounted package.   Chemical injection skids IETL supplies pre-designed and packaged Chemical Injection Skids for a wide range of liquid chemical injections.
