Thermodynamics Analysis of ORC for Heat Recovery from Decomposition of Phosphogypsum

Abstract

This paper examine the thermodynamic and physical properties of some fluids used in organic Rankine-cycles (ORC) supplied by waste energy sources. Then Energy requirement and recovery system performances are analyzed using realistic design operating conditions. Thermodynamic efficiencies and alternative results are calculated by varied some recovery system operational parameters at numerous reference temperatures. With relevancy projected application, equations and graphs area unit only if interrelate the recovery system operational parameters for a couple of getable operational fluids with computation results. An analysis of a ORC cycle was performed to determine the increase in power output that would be achieved by adding a bottoming ORC to the utility-scale steam Rankine cycle, and confirm the impact of close conditions (heat sink temperature) on power increase. For the chosen station location, the massive distinction between the winter and summer temperatures encompasses a sizeable impact on the ORC power output. The recovery of the fatal heat leads to two axes of complementary thermal valorization: a valorization in house, to answer to the needs of heat specific to the company; an external valuation. In this study, we will valorize the thermal energy released by the phosphogypsum desulfurization system and protect the environment.
