Combined Heat and Power (CHP)What is CHP?
An efficient way to generate heat and power togetherWhat does CHP provide to the rest of the project?
ElectricityPure water
Why is CHP needed?Improves fuel efficiencyCuts down energy costReduces investment
Our Goal“To optimize energy production and consumption of the
whole plant .“ - Prof. Perl

Cooling Water SystemFunction: Convert Supply Water to Industrial Cooling
Water
Types of Cooling Water Systems:Once-ThroughOpen RecirculationClosed Recirculation
Design Considerations:Deposition of SolidsCorrosion of EquipmentMicrobial Growth
Hydraulic Fracturing Fluid (Frac Water)
Composition: 80-99% water
Additives that need to be removed:Proppant (sand, silica)Gel
Relevant Separation Processes:ClarificationPrecipitation Softening
Treatment ProcessesClarification
Coagulation – precipitationFlocculation – clumping of impuritiesSedimentation – settlingFiltration
Precipitation Softening – for Silica ReductionAddition of Lime – precipitationSedimentation – settlingFiltration
Boiler Feed PretreatmentWhat is boiler feed pretreatment?
A series of separation processes to provide pure water for boiler
Why do we need boiler feed pretreatment?Maximizes lifetimeMaximizes performanceReduces costs
Boiler Feed PretreatmentDesign Basis
Production scale – Required amount of water for boiler
Feedstock – Reclaimed water Blow down – Hazards for environment
Main Pretreatment Processes ClarificationFiltrationReverse OsmosisIon Exchange
