4 Bilfinger EMS GmbH Your german partner for the renewables technologies 4 > 35 years in gas processing (NG + BG) > 100 references > 530 employees > Turnover 2013: > 72 m EPC for the biogas upgrading unit EPCM for the full biogas plant Concept and feasibility studies Design & Fabrication Implementation of O&M procedures

5 Bilfinger EMS GmbH OASEgreen Process 5 Simplified process Desulfurisation before or after upgrading No pre-dehydration Long absorbent lifetime H2S < 5 mg/m³ possible operation slightly above atmospheric pressure High biomethane recovery Extremely low methane losses <0,05% Methane enrichment to > 99,0 Vol.% Advantages for grid injection Compression after CO2 removal Smaller compressors required

6 Bilfinger EMS GmbH Advantages of OASEgreen Process 6 Advantages of OASEgreen : Chemisorption of H2S Developed solvent: BASF SE, Bilfinger EMS, Wingas Methane-loss < 0,05% Oxygen-resistant Low pressure process ( at atmospheric pressure) Minimum loss of solvent < 5% per year) No unmeant reaction with gas-components Low regeneration-temperature Non hazardous solvent (WGK Class 1) High durability of min h (up to h) Advantages of our upgrading unit: Low maintenance cost Low Energy consumption E <0,06 kwh/nm³ raw biogas T < 0,7 kwh/nm³ raw biogas < 0,4 kwh/nm³ if using excess heat Use of different heat-sources possible Upgrading from 600 up to Nm³/h Fully automated process (daily inspection <1h) Modular compact skid mounted standarized design

12 Bilfinger EMS GmbH Membrane-upgrading process 12 Process Pre desulfurisation Pre dehydration Operation at barg 2 or 3 membrane stages High biomethane recovery Extremely low methane losses Methane enrichment to > 99,0 Vol.% Advantages for grid injection Compression in many projects not required Outlet pressure > bar g

13 Bilfinger EMS GmbH Advantages of membrane upgrading process 13 Advantages of membranes Long-time proven hollow fiber polymer membranes on landfill and biogas applications (est.lifetime 15 years) Methane loss < 0,5% High CH4-quantity in the biomethane (CH4 >98%) Reduction of O2 Biomethane quality guarantee Advantages of our plant Low maintenance cost and high energy efficiency fully automated process (daily inspection <1h) only electrical consumption (<0,26 kwh/nm³ raw biogas) heat recovery possible Outlet pressure >16barg, in most cases no need for increasing the pressure for injection Upgrading from 150 up to Nm³/h No water consumption Fully automated process (daily inspection <1h) Modular skid mounted standard design
