    2. Unison Solutions, Inc. Overview Biogas Compression/Treatment System Design and Fabrication 130 Systems In Operation Turnkey Waste-to-Energy Systems Gas Testing and Analysis Multiple Awards for Biogas Systems (EPA project of the year 2003 & 2009, 2006 SWANA Gold Award and 2010 ACEC Grand Conceptor Award)

    3. Fabrication Facility

    4. Assembly and Testing Area

    5. LFG for Drying Ocean Spray Cranberries

    6. Biogas Treatment Systems What is driving the need for increased gas treatment on biogas fueled generation and direct use projects?

    7. Equipment Damage and Performance Issues

    9. Key System Components Hydrogen Sulfide Removal Moisture Removal Compressor or Blower Siloxane Removal Controls/Automation CO2 Removal

    10. Why Hydrogen Sulfide Removal? Equipment Damage from Corrosion (Hydrosulfuric Acid) Health and Safety Issues (1000ppm will cause an individual to lose consciousness.) Odor Control Causes fouling of siloxane removal media

    11. Types of Hydrogen Sulfide Removal

    12. Iron Sponge

    13. Why Moisture Removal? Prevents condensation downstream Improves energy content of gas Condenses into compressors Formation of weak acids from interaction with H2S and CO2 Fouling of Siloxane removal systems

    14. Types of Moisture Removal Equipment Knockout Suction Scrubber or De-mister Ambient Air Cooler Refrigerated Dryer Glycol Chilling

    16. Types of Gas Compression

    17. Centrifugal Blower

    18. Why Siloxane Removal? Organosilicons produced by Dow Corning Used in the manufacture of many commercial products including: makeup, tooth paste, shampoo, lubricants, etc. Present in almost all digester gas from 500ppbv to 140,000ppbv. MM, D4 and D5 account for 75% to 95% in biogas. (2, 4 and 5 silicon atoms per molecule. Do not breakdown during processing in anaerobic digesters.

    19. The Problem When VOCs and Siloxanes are in the digester gas:

    20. The Damaging Results Pressure and temperature transform the Siloxanes into various abrasive silica forms from sand to glass. Causes damage to boilers, internal combustion engines and microturbines. Usage in commercial products is increasing at 5% to 10% annually. Problems with Siloxanes are here to stay.

    21. Siloxane Damaged Piston

    22. Processes for Removing Siloxanes from Biogas Fixed Bed Carbon Filters (Norit, Calgon, Carbon Air) Fixed Bed Silica Gel Bead Filters Regenerated Desiccants (GES Systems, Venture) Regenerated Carbon (Jenbacher TSA) Regeneration with Micro Wave-design phase

    24. Why CO2 Removal? Opportunity to create a fuel that can be injected into a pipeline. Create a compressed vehicle fuel equivalent to CNG.

    25. CO2 Removal Processes

    26. Budgetary Biogas System Costs 50scfm Systems

    27. Biogas End-Use Technologies Direct Use to Boilers Reciprocating Engine/Generators Micro-Turbines (Capstone) Turbines (Solar) Pipeline Vehicle Fueling
