Abstract

Heat sources such as geothermal brine, biomass, and other waste heat sources have the potential to be recovered. Organic Rankine Cycle (ORC) plants can use to convert low-temperature heat sources into electrical energy. Working fluid selection for a simple system of the Organic Rankine Cycle plant is essential because the system works in limited conditions. This research will analyze the performance of several fluids that can use as working fluids. Simulation using EES, the selected fluid must have excellent cycle efficiency, a high volumetric vapor flow rate, and a high expansion pressure difference. Working fluids compared at a constant pump flow rate of 4.5 liters/minute with a heat source temperature range of 70-180 oC to obtain thermal efficiency, volumetric vapor flow rate, and expansion pressure difference of the expander. The simulation results obtained 11 types of work fluids that meet these criteria. Considering environmental aspects, three types of working fluids are ideal for testing. N-Pentane as a working fluid with the highest volumetric vapor flow rate. R-123 as a working fluid with the highest cycle efficiency. R-1233zd as a working fluid with the highest expansion pressure difference.
