  2. Combined Heat and Power (CHP) • What is CHP? • An efficient way to generate heat and power together • What does CHP provide to the rest of the project? • Electricity • Pure water • Why is CHP needed? • Improves fuel efficiency • Cuts down energy cost • Reduces investment • Our Goal • “To optimize energy production and consumption of the whole plant .“ - Prof. Perl

  3. Block Flow Diagram Grid Plants Reject (Blow Down) Power Block Natural Gas Cooling Water Makeup Water (Frac Water) Reclaimed Water Boiler Feed Prep Plants Plants Reject (Blow Down)

  4. Combined Heat and Power Natural Gas Coal Steam Prime Mover Generator Heat Exchanger Thermal System

  5. - Reciprocating Engines ( Hot Water/ Low Pressure Steam) - Industrial Gas Turbines (High Pressure Steam) - Steam Turbines (Large Pressure Drop Requirements) - Micro-turbines (Relatively Small Capacity Required) CHP Prime Movers

  6. Gas Turbines Conventional Turbines Microturbines 20-300kW Aeroderivative Power output : 16-120 MW Efficiency: ~54% Emission: 15-25NOxpp/ 25ppmCO Industrial Small duty Power output : 5-50 MW Efficiency: ~35% Heavy duty Power output : 11-340 MW Efficiency: ~55% Emission: 4-15NOxpp/ 25ppmCO Power block - Gas Turbine options

  7. Power block- Steam Turbine options Steam Turbines Backpressure Turbine Condensing Turbine

  8. Power Block

  9. Cooling Water System • Function: Convert Supply Water to Industrial Cooling Water • Types of Cooling Water Systems: • Once-Through • Open Recirculation • Closed Recirculation • Design Considerations: • Deposition of Solids • Corrosion of Equipment • Microbial Growth

  10. Hydraulic Fracturing Fluid (Frac Water) • Composition: 80-99% water • Additives that need to be removed: • Proppant (sand, silica) • Gel • Relevant Separation Processes: • Clarification • Precipitation Softening

  11. Treatment Processes • Clarification • Coagulation – precipitation • Flocculation – clumping of impurities • Sedimentation – settling • Filtration • Precipitation Softening – for Silica Reduction • Addition of Lime – precipitation • Sedimentation – settling • Filtration

  12. Boiler Feed Pretreatment • What is boiler feed pretreatment? • A series of separation processes to provide pure water for boiler • Why do we need boiler feed pretreatment? • Maximizes lifetime • Maximizes performance • Reduces costs

  13. Boiler Feed Pretreatment • Design Basis • Production scale – Required amount of water for boiler • Feedstock – Reclaimed water • Blow down – Hazards for environment • Main Pretreatment Processes • Clarification • Filtration • Reverse Osmosis • Ion Exchange • Available Suppliers • GE; Nalco; Siemens; Veolia

  14. Q & A • Welcome to ask questions
