TECHNOLOGY difgen
Pressure the forgotten energy source Two ways of reducing pressure: Discharge to open basin Conversion to kinetic energy and back again (pressure reduction valve) Common for both types energy from pressure drop is lost! A third method is to control the pressure with a rotating barrier device, which is harvesting the energy from the pressure drop as electricity Pressure reduction Pressure & leak mgmt Power produc -tion Feed-in tariffs/ CRC s Flow meas -ure Manual PRV X Remote ctr. PRV X X difgen X X X X X
Difgen pressure reduction Volumetric displacement turbine - impellers form a physical, rotating barrier between the upstream and downstream fluids A fixed volume is dosed through the turbine for each revolution By applying load to the shaft, rotational speed is retarded, and a differential pressure is created By dynamically controlling the generator speed, the upstream/- downstream pressure is also dynamically controlled The load is an electric generator, converting work to electricity Impellers acting as barriers are functionally comparable with mechanical transmissions
Speed ref. difgen Pressure management & Grid Connection DCS Press. Setpoint DC-bus Pressure set point from DCS Pressure control loop with speed control adjust the pressure dynamically Control To grid Connected to the grid in the same way as wind turbines Always connected Dual front-end VFD s to transform to grid voltage and frequency Production determined by available flow/pressure Parallel turbines controlled by one controller
Predictability As opposed to wind, solar, tidal and wave, Difgen provides predictable power supply In a well known industrial process, the excessive pressure pattern is known In a utility system (e.g. drinking water supply), the power supply even correlates to energy demand levels & pricing
Flow rate difgen Return on investment Available power (and ROI) is a product of Flow rate Available pressure reduction Local incentive schemes, feed-in, CRC, etc Revenue from power generated can offset high utility power costs Excellent ROI Normal ROI Poor ROI Long term ROI Pressure
Typical applications Process plant cooling water (ref. offshore production platforms) Process trains Desalination plants Food processing Drinking water Closing the energy loop
Drinking water supply Features Electricity production from intended pressure reduction Accurate upstream/downstream pressure control Enables dynamic pressure management, e.g. to reduce leakages Built-in flow measurement Dampening of pressure transients Qualifies for various renewable energy grants/feed-in etc. Included in the 2009/10 Carbon Trust list of approved products
Requirements for installation Delivered with standard flange in both ends Simple replacement of existing pressure chokes Requires space for the generator next to, over or under difgen Simple grid/site connection via VFD s
IVAR pilot site - Norway Tested different versions since spring 2008 Drinking water treatment plant 7,3 bar pressure Max 7,3 bar diff. pressure 65 l/s 55 kw
