A Working Fluid Assessment for a Biomass Organic Rankine Cycle under Different Conditions

Many thermal resources are not reasonably used in the chemical industry’s production process. To recover waste heat from organic residue-calcium carbonate (CaCO3), which is added to inhibit hydrogen production, an Rankine cycle (ORC) system applied this research. An ORC can reuse low-temperature that fully utilized. In study, mathematical model of biomass power generation constructed. Five working fluids, R11, R113, R123, R141b, and R245fa, were selected physical characteristics safety fluids. The application case absorption a simulated by Aspen Plus V11 software, so as study analyze influence different fluids conditions on performance obtain preferred under conditions. At same time, economic evaluation entropy method evaluated using investment profit rate PRI angles. It be found R11 R141b have advantages, but does advantages environmental aspects. Through research, it difficult fluid adapt any This paper provide basis for subsequent research selection system.
