3 Mission Statement We at FEG avoid the use of green labels and eco statements often associated with sustainability. We believe that through a holistic approach to engineering and process design, significant and lasting energy efficiency and reductions can be achieved. Whole life assessments of technologies and schemes can be difficult to perform and in many cases the results are questionable. However, we at FEG believe that through considered and inclusive design principles, an organisation can achieve the foundation of sustainability and reap the genuine and tangible economic benefits.

4 Sources of 'Waste' Heat Opportunities for cost-effective heat recovery: Ventilation System Extracts Air Compressors Refrigeration Plant High Temperature Exhaust Gas Streams from: Furnaces, Kilns, Ovens and Dryers Hot Liquid Effluents Power Generation Plant Process Plant Cooling Systems Boilers Providing Heat for any Process Boiler Flue Gases Steam Boiler Blowdown Flash Steam Process Cooling Systems Heat Rejection Hot Exhaust Air from Dryers, etc. Heat Stored in Products Leaving a Process Heat in Gaseous and Liquid Effluents Leaving a Process Heat in Cooling Hydraulic Oil Systems

5 Case Study 1 Waste Heat Application: Heat Recovery System Client: Kimberly Clark Industry: Tissue Manufacturer Project: Compressor Heat Recovery Design, Supply, Install, Site Supervision, and Commissioning a turnkey project to recover waste heat from compressors and heat various areas of the factory. Installation had to be completed without affecting the compressor uptime as this directly impacted on production. Involved site management, control of contractors, budget management and programme control.

6 Case Study 2 Waste Heat Application: Client: Industry: Project: Product Cooling Hood to Temper Palm Oil Kerry Foods Food Manufacturer Warm Room The waste heat from the air drafted water chiller used for the cooling hood was recovered and blown into a bespoke enclosure, to raise the temperature of Palm Oil IBC s during the winter.

7 All good projects and good engineering practice, however

8 The Problem Many plants that generate waste heat do not have an obvious requirement to re-use or exchange this heat. Worldwide Estimates... 40,000 GWh of energy lost from steam systems 20% to 50% of industrial energy input is lost as waste heat The key is to be able to have a viable way of turning this wasted energy into useful work.

9 The Solution The Heliex Steam Screw Expander offers a solution to recover electrical power from process heat and steam systems. Clean Electricity From Wet Steam Waste Heat Recovery (WHR) Pressure Reduction Valve (PRV) Processes Process Steam Exhaust Gas Energy Recovery Biomass and Biogas Installations Diesel and Gas Engine Exhausts Concentrated Solar Power (CSP) Geothermal Power Sites

10 Heliex Technology The Heliex Steam Screw Expander Well proven screw technology used in the production of compressed air Uses the pressure reduction step in steam distribution circuits to generate clean electricity Work where turbines cannot because they can process saturated steam Work at higher temperatures than ORC's

11 Heliex Steam Pressure Reduction Heliex Open System The Heliex device replaces the Pressure Reduction Valve in a process line or in the discharge line for waste steam. Steam at Transmission Pressure Bypass The Heliex generates electricity that can be used internally or sold back to the grid through the feed-intariff. Fuel Boiler Pump PRV Heliex Power Out Generator Process Heat Out Steam at Process Pressure or Venting Replacement of an Existing Pressure Reduction Valve

12 PRV Case Study By running the Heliex in parallel with the PRV device process security can be achieved. Steam Mass Flow Pressure Drop Nett Electricity Power Working Hours Total Electricity Power Electricity Power Value Electricity Value 3.35 t/hr 17.8 Bar (A) 72.5 KWe 8500 hr/yr 616,250 KWh 0.07 / KWh 43,137 / yr

13 Heliex Waste Heat Recovery Heliex Closed System A suitable waste heat source is used to generate steam in a dedicated boiler feeding the Heliex device that recovers the waste energy in the form of electricity. Cooled Fluid Steam Boiler/Heat Exchanger Heliex Power Out Generator Pump Process Hot Water Hot Fluid

14 Waste Heat Case Study Glass Furnace Flue Gas Heat Recovery: Available Gas Temperature 450 C Gas cooled to 200 C Gas Flow Rate 20,000 Nm3/Hr Available Energy 2019 KW Steam Raised to 15 Bar (A) Steam Flow Rate 3.18 t/hr Nett Electricity Power 147 Kwe Operating Hours 8200 hr/yr Total Electricity Power 1,205,400 KWh Electrical Power Value 0.07 / KWh Electricity Value 84,378 / year Carbon offset by Project 422 t/a Avoided Coal use 612 t/a Thermal Power Remaining 1841 KW

15 Total Package FEG Ltd will supply full 'Turn Key' packages incorporating the Heliex device. This includes maintenance and service plans tailored to the clients needs. We also offer associated services: Flue Gas Analysis & MCERTS Continuous Emissions monitoring Filter Plant Condition Surveys LEV Testing ESOS Assessments
