3 Waste to Energy -OUTLINE-

4 WASTE GENERATION Jubail Petrochemical Industry ( Basic/ Refineries/ others ). Examples:  Aqueous solutions (w/out organics; spent caustic)  Solvents and organic solutions  Heavy metal solutions  Oils/ greases/ water mixtures  Organic sludge  Other (Activated carbon/ resins/absorbents/ biosludge/ filters/ chemicals/ sand/ asbestos/ tar/ fly ash/ used catalyst)

5 WASTE GENERATION QUANTITIES Treatment/ Disposal Method Received /MT Wastewater96,285 Landfills55,057 Incineration18,058 Total169,400

6 Solar evaporation Physical Chemical Incineration Waste Treatment

12 Mechanical Evaporator 2 Evaporator units 1 Drier Capacity: 100m 3 day Wastewater Distilled Water Residue (80% solids) Steam is utilized to raise wastewater temp to increase evaporation rate

13 Ammonia Stripper Ammonia contaminated wastewater 250m 3 day Steam is used in a heat exchanger to heat up waste (70˚C) Temp increases stripping efficiency

14 Turbine Generator Power Output: 630Kw Steam (at 21bar) is utilized to generate power. Generated Power Usage: Lighting Power air compressors (bubbling systems/ other uses) 400w

15 General Cleaning Drums Waste containers Filters Trucks

16 Water Recycling Evaporator (4.3) Cooling Tower (4) Bleed (1) Wastewater All units: m 3 /hr Wastewater Boiler (5) RO (8.75) Stack (2.95) Scrubber (3) Bleed (0.8)
