Abstract

Indonesia remains highly dependent on fossil fuels and non-renewable energy sources, which contribute to global warming. On the other hand, the country has yet to fully develop waste heat utilization, especially through organic Rankine cycle (ORC) systems, to help reduce reliance on fossil fuels. Take an example, Sorong Gas Engine Power Plant uses diesel engine in which the exhaust gas can produce up to 369℃ of flue gas which get released directly into the atmosphere. This paper presents a thermodynamic calculation and analysis of Organic Rankine Cycle using waste heat from the exhaust gas. This paper includes calculation of the net power output, thermal efficiency, mass flow rate among several choices of refrigerant. Among 20 refrigerants available in Indonesia, R600 offers zero ODP, GWP number of 4, and the lowest refrigerant mass flow rate that can reach up to 13% of Rankine system efficiency. These factors provide valuable strong starting points in designing ORC using waste heat recovery promoting sustainable energy for communities.
