Learning Outcomes
On successful completion of this module the learner will be able to:
LO1 Conduct energy balances on single process units, without reaction, or with combustion.
LO2 Conduct energy balances on systems of thermal units
LO3 Devise appropriate control strategies to thermal energy generators and consumers
LO4 Apply the concept of Pinch Technology to heat and power networks to identify the major factors that affect the overall performance of these networks.

Module Content & Assessment

Indicative Content
Energy flow balancing and mapping
Energy balancing: linking energy accounting and energy conversions. Energy balances on non-reactive systems. Combustion balances. Utility energy balances: steam, thermal fluids, cooling and refrigeratin systems. Cogeneration and trigeneration in balances. Representation of energy flows for complex units, sites, districts and regions. Use of Sankey diagrams. Identification of energy recovery potential.
Process integration
Heat exchanger networks. Composite curves. Problem Table Algorithm. Minimum approach temperatures, pinch and pinch significance. Utilities, minimum utility requirements, grand composite curve, threshold problems. Heat exchanger networks, minimum number of units, area estimates. Steam and cooling systems. Cogeneration and heat pumps. Cost targets. Retrofit issues.
Measuring and controlling thermal systems
Identification of key parameters (efficiency, safety, environmental) in thermal process equipment. Measurement methods, direct and inferential. Control strategies for thermal process equipment e.g. steam and hot water boilers, cooling water systems, refrigeration plant, heat pumps, cogeneration plant.
