Process OverviewUltra-Clean GasifierSmall Scale FT ProcessWET-EIG’s Technology4

Human Sludge ProcessingDewaterOriginally sewage is ~80% water, so de-water to ~40%Waste heat will reduce this to ~30% before entering gassifierGasify & CleanScrub away sulphur (H2S), nitrogen (N2) and oxygen (O2)Produce clean synthesis gas (CO and H2)Burn to generate electricity or condense into dieselGenerates ~1.2 MWhr/tonne of dewatered sludge, or Produces ~230 litres/tonne of dewatered sludge5

Technology BackgroundSince 1990 the Company has installed over 1000 low NOx burnersIt has set the California’s emissions standards 4 times, currently < 9ppm NOx, < 50ppm COFirst experience in gasification in Daoling, China in 1993Makes 24,000 gals/day of fuel from tyresPyrolizetyers at 400-450°C to make black oil suitable as coal substitute for power production, but not good for autos, more like light bunker fuel with ~0.4% sulfurBuilt a similar 12,000 g/d tyre plan in Nankang, Taiwan in 2000Produces a cleaner fueldItaly glass recycling plant Since 4yrs, 100 kg/hr, remove plastic & metals from auto glassHeat used for power generation to run the plant, though still in pilotLarger plant being designed at 500 kg/hr220 kg/hr plant in Oregon generates 265kW net powerHuman sludge plant in Los Angeles (Carson), demo plant @ 50 kg/hrHas led to orders for 4 plants at 1-10 ton/hour for Brazil, China, Malaysia, India6

Pyrolysis StepProcesses carbonaceous material, such as coal, wood chips or sewage sludge into carbon monoxide and hydrogen (CO + H2)Partial vacuum – reduces oxygen content in the chamberReducing oxygen content reduces CO2 + SOX formationPatented burner system leads to lowest NOX emissions in the worldRotating feed column circulates coal in reactor over a period of time (30mins -55mins)Inert ash is collected at the base of the reactorIdeal feedstockWater content ~25%Increases hydrogen productionLow ash / high calorific conditionLow SulphurReduce cost of clean up stage7C + H2O -> H2 + CO

Low Temp GasifierTechnologyGasifies organic matter, coal or pet-coke at 750-1000 F to produce syngas (H2, CO and CO2) Syngas used to create synthetic diesel and other petroleum products Remainder used to generate electricity for plantOperates too cool to for CO or NOx400-650°C (750-1200°F) vs 980-1650°C (1800-3000°F)12 proven units in the field operating various feedstockCoal, pet-coke, municipal solid waste (MSW), tires, plasticsAutomatic augur system removes slagLess maintenance, longer catalyst life8

Steam Reforming stepThe F-T process requires a ~2:1 hydrogen to carbon monoxide ratioMost coal types do not produce enough hydrogen Additional hydrogen is created in the reforming stepPyrolysis step also produces a large amount of methane, perfect for reforming with steamCH4 + H2O  3H2 + COCH4 + 2H2O  4H2 + CO2Depending on operating conditions either reaction 1 or 2 will be favoured. Reaction 2 generates more hydrogen but as a consequence generates more CO2% gas composition after pyrolysis9

Fischer-Tropsch ProcessAs previously stated the H2 and CO must be fed into the reactor as 2:1 ratio to maximise conversion efficiencyAll sulphur and other contaminants must be removed to prevent poisoning the catalystThe process uses a floating bed reactor with a high boiling point fluid to transport the F-T catalyst Encourages mixing and reduce chance of carbon deposits on catalystThere are 2 types of catalyst WET-EIG Asia promotesIron OxideCheaper but more susceptible to pressure changes. Produces lighter hydrocarbon chainsCobaltProduces a constant stream of product not depending on pressure. Also catalyst tends to produce heavier compounds, ideal for refinery specificationReaction formula:10(2n+1) H2 + nCO -> CnH2n+2 + nH2O

50kg/hr Test Plant11In addition to sewage sludge, the company has gassified over 75 types of coal, a dozen different plastics, rubber, rail road ties, municipal solid waste, medical waste and biomass (rice straw, grass, wood chips, soy bean shells, switch grass), chicken manure, cow dung, etc.Test burn of synthesis gasBurner / GasifierFischer Tropsch UnitSynthetic Diesel

Sewage Sludge-to-Diesel Pilot Plant12Human sludge plant in Los Angeles (Carson), demo plant @ 100 kg/hourHas run 24 hours/day almost continuously since January, 2009Avoids $70/ton transport charge to San DiegoReduces volume by 92%, lose 1.8%, remaining residue (carbon/phosphorus) makes good fertilizerGive back surplus waterCurrently planning for 60 ton/hour plant for 3.5 million population of Long Beach and surrounding area

1,500 L/day modular plant132 pyrolysis units @ ½ ton/ hr capacity

3 towers if sulphur content is over 1%

1 reforming step – hydrogen production
