Analisis Generator dan Perbandingan Fluida Kerja pada Siklus Rankine Organik Pembangkit Listrik Biomassa dengan Menggunakan Software Aspen Plus

Abstract

The Organic Rankine Cycle (ORC) is a thermodynamic cycle that can be used to generate electrical energy. The Organic Rankine Cycle is a cycle of utilizing low-temperature heat (waste heat) in power plants in generating electrical power. The efficiency of the organic Rankine cycle is influenced by several factors, including the temperature and pressure of the working fluid. using experimental methods. The research variables include calculations using the gasification method in calculating electrical energy in the CPP and calculating the results of the organic Rankine cycle circuit experiment by taking into account the temperature and pressure of the working fluid using Aspen Plus Software which is analyzed using statistical methods. The results of research using the gasification method on fuel CPPs produced a power of 27,279.38 Mw / year for coconut shells, 6,489.66 Mw / year for rice husks and 532.62 Mw / year for corn cobs. as well as for the organic rankine cycle series of rice husk waste produced the largest power of 8,336.67 kw, for coconut shells of 569.723.95 Kw, and on corn cobs of 358,639.63 with the efficiency value of organic working fluid in R-22 of 25.37% and for organic working fluid R-32 of 11.92% at 125°C on coconut shell waste, it can be concluded that the temperature of the working fluid has more effect on the efficiency of the organic Rankine cycle than the pressure of the working fluid. To increase the efficiency of the organic Rankine cycle
