3 PART I : Scrubber

4 The FlareGas Cleaner Biological desulphurization technology very low operational costs (no usage of caustic soda or similar chemicals). Highly economically. Environmentally friendly. Proven Technology more than. H2s Content of Flare Gas 1,182 ppm to be reduced to the desired level of < 5 ppm H2s for use as CNG as an alternative automotive fuel.

5 The FlareGas Cleaner Consist of: 4 x FRP-tank D=2,0 m x H=10,0 m - Insulated acid resistant tank incl. ladder and platform - Gas distribution system - Spray system - Drain system - QSR - system - Packing media - Heat coils and heat return valve

6 The FlareGas Cleaner Consist of: Process Technique Unit (PTU) - Insulated 20 container placed besides the tank -- Circulating/drain pump -- Fertilizer dosing unit -- Water flow meter -- PLC controller -- Electrical installation, incl. lighting - EX gas detector system - Start-up bacteria - Air Blower and BioGas Analyser.

7 Disposal of Water Waste The effluent from the scrubber is water with up to 8% SO4 ( mg/l sulphate) and with a ph of down to Despite of the low ph you can dip your finger in the effluent w/o getting your skin burnt. The typical application is that the effluent is mixed with the treated waste water or organic waste and recycled to fields as fertilizer. Per day 2,5m3of waste water will be disposed. Per day 2,5m3of fresh water is required. Per day approx. 200kg of S-Fertilizer will be produced.

8 The LP Booster Compressors 4+1 Claw compressors Dry and contact-free running compressor for operating in potentially-explosive atmospheres Inlet:8-15mBarG Outlet: 30kW, 400VAc, 50Hz EC directive 94/9/EG ATEX Process heat will be used for heating the Tanks during winter time and Drying the gas

9 The Chiller Cooling circuits w/refrigerant gas: R407C Evaporator with stainless steel plates brazed with copper. Condenser with stainless steel plates brazed with copper. With Dimister. 400VAc, 50Hz.

10 The Dryer Closed circuit regeneration without gas consumption 2 column design without interruption Water discharged 36 kg for a 8-hours cycle and 55 kg in case of hours cycle Dew Point: -60 C 22kW, 400VAc, 50Hz

11 PART II : HP Boosters

12 The HP Booster Compressors 3+1 HP Booster compressors 1,6BarG inlet 200BarG outlet Aircooled With el. Control cab. ATEX 150kW, 400VAc, 50Hz

21 OBJECTIVES OF EMIRATES GAS CNG PROJECT Contribute to building a sustainable future, promote clean environment in Dubai, and reduce air pollution; Develop the Natural Gas Vehicle industry as an alternate and sustainable energy solution which would reduce fuel costs; Reduce the carbon footprint of the Dubai by substantially reducing the exhaust emissions and pollutants such as carbon monoxide, carbon dioxide, nitrous oxide and other ozone depleting substances; Being the most favored tourist destination, to bring Dubai in league with the leading developed cities of the world to promote CNG as an alternate environmentally friendly fuel

22 EMIRATES GAS PROPOSED CNG INITIATIVE CNG Mother Station 1 Existing Mother Station connected to DUGAS pipeline 1 Mother Station at Al Aweer Sewerage Treatment Plant CNG Daughter Station 4-5 Daughter Stations to be set-up as Dedicated Stations on fleet owners premises 1-2 Daughter Stations to set-up on existing ENOC petrol stations CNG Mobile Filling Unit 1 Existing MFU for small fleets with capacity of 800 cubic meters on board storage

23 EMIRATES GAS MARKETING STRATEGY Installation of CNG Daughter Stations at Dedicated Fleet Owners premises in Dubai Address potential Government Fleets

34 CNG ADVANTAGES The Environmentally Clean Advantage Compressed natural gas is the cleanest burning fuel operating today CNG vehicles produce the fewest emissions of any motor fuel In gasoline vehicles, fueling emissions account for at least 50% of a vehicle s total hydrocarbon emissions CNG is a fossil fuel that generates less air pollutants and greenhouse gases Tailpipe emissions from gasoline operated cars release carbon dioxide, which contributes to global warming. This is greatly reduced with natural gas.

35 CNG ADVANTAGES The Performance Advantage Natural gas gives the same mileage as gasoline in a converted vehicle Dedicated CNG engines are superior in performance to gasoline engines CNG has an octane rating of 130 and has a slight efficiency advantage over gasoline Because CNG is already in a gaseous state, NGVs have superior starting and drivability, even under severe hot and cold weather conditions NGVs experience less knocking and no vapor locking

36 CNG ADVANTAGES The Maintenance Advantage Some fleet operators have reduced maintenance costs by as much as 40% by converting their vehicles to CNG Intervals between tune-ups for natural gas vehicles are extended 30,000 to 50,000 miles Intervals between oil changes for natural gas vehicles are dramatically extended anywhere from 10,000 to 25,000 additional miles depending on how the vehicle is used Natural gas does not react to metals the way gasoline does, so pipes and mufflers last much longer
