The working fluid in both systems was assumed to be R123 because of its thermodynamic and environmental properties. These systems used the waste heat of exhaust gas from a cement plant. Thermodynamic and thermoeconomic analyses of two trigeneration systems were performed through Engineering Equation Solver (EES) software.
