This study performs the simulation and energy, exergy, economic analyses of an organic Rankine cycle (ORC) integrated with a natural gas combined cycle. Working fluids studied in this research are ammonia, isobutane, R-11, R-113, R-141b. The power plant ORC simulated using Aspen HYSYS software. results show that leads to improvement thermo-economic indexes plant. sensitivity analysis also demon...

An intermediate fluid vaporizer (IFV) is a typical of liquefied natural gas (LNG), which used in large number LNG terminals. Since it requires supply seawater during its operation, generates lot energy consumption. In this study, to reduce the consumption regasification system, heat transfer process was first numerically calculated, and coefficient IFV determined for different inlet temperature...

Fatty acid adalah salah satu bagian dari produk industri oleochemical. Salah hilir yang bergerak pada produksi fatty (asam lemak) PT. Domas Agrointi Prima. Pada Prima diproduksi di acid-1 plant. Untuk menghasilkan sesuai spesifikasi pasar, maka perlu dilakukannya proses pemisahan dan pemurnian kolom distilasi/fraksinasi. utama plant banyak mengandung asam oleat (C18:1) dipisahkan dimurnikan dis...

The global production and consumption of plastics have continued to increase. Plastics degrade slowly, causing persistent environmental pollution Developed waste plastic recycling methods are discussed in this report, with a focus on the dissolution/reprecipitation technique restore low-density polyethene (LDPE) wastes. Aspen HYSYS is used simulate LDPE. Turpentine/petroleum ether (TURP/PetE) c...

In recent years, using new methods in utilization of energy resources has become necessary due to environmental pollution and restriction of energy resources. The hybrid system presented in this article produced power with SOFC and Stirling engine. The purpose is to analyze a 50 kW Solid Oxide Fuel Cell that could produce enough thermal energy for a 10 kW Stirling engine working in the hybrid s...
