COMPARATIVE PERFORMANCE ASSESSMENT OF DIFFERENT ORGANIC RANKINE CYCLES FOR FLUE GAS WASTE HEAT RECOVERY IN GLASS INDUSTRY APPLICATIONS

Nowadays researchers have taken an interest in waste heat recovery systems, driven by the rising cost of fuel and possible pollutants. Utilizing renewable energy sources and waste heat reclamation are practical ways to generate power without adding to greenhouse gas emissions and harming the environment, as they can only reach temperature that is lower than those of fossil fuels. Thus, in this study a different organic Rankine cycle (ORC) configuration is simulated on aspen software that drives on waste heat of the glass industry, and hydrocarbon is opted as the working fluid. The 3E (i.e., energy, exergy, and economic) analysis has been done to evaluate the best ORC configuration with opted working fluids. The zeotropic mixture in all the chosen configurations is a mixture of benzene/nonane and toluene/cyclohexane at a 0.5/0.5 mass fraction. regenerative ORC will generate the maximal work, which is 14.5% and 21.2% more than recuperative ORC and basic ORC, in terms of the study. While using T+C as an organic fluid, the maximum energy and exergy efficiency by using T+C has been evaluated at 48.38 and 72.86%, whereas with B+N it will be 37.19 and 55.28% with the maximized capital cost of 3,396.86 k$/year.
