Abstract. Natural gases containing impurities, namely carbon dioxide (CO2), heavy hydrocarbons, hydrogen sulfide (H2S), and water vapour, need treatment for removing acidic (CO2 H2S) to reduce corrosion enhance the heat capacity of gas. This gas is commercially known as "sour", typically, sour any that contains significant levels sulfide. The presence can affect natural quality, which also lead...

The optimal design of single mixed refrigerant (SMR) natural gas liquefaction process is decisive for upgrading the liquefied (LNG) value chain and can be achieved using simulators derivative-free optimization techniques in simulation–optimization frameworks. work consumption reduced by modifying flowsheet manipulating refrigeration cycle thermodynamic conditions composition. goal this paper en...

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...

This study investigates the performance of co-firing palm kernel shell (PKS) and pulverized coal in a steam power cycle. The process simulation software Aspen Hysys was used simulation. analyzed various emitted combustion product gases. cycle efficiency Power output for each fuel sample blend carried out. provided basis comparison sample. Sample D with mix ratio 80 (coal)-20 came out best havin...

En esta investigación se hizo el diseño y la simulación de un gasificador carbón con captura dióxido carbono para obtención hidrógeno, mediante software Aspen HYSYS versión 9.0; utilizó como materia prima antracítico bituminoso, procedente diferentes regiones Colombia. Las características del carbón, así las condiciones los demás flujos alimentación al reactor, inciden en finales gas producto s...

Exergy analysis is an important tool to identify the improvements in various industrial processes. In this study, existing steam power plant examined based on energy and exergy analyses. The network comprised of two sections, one them used for paddy drying, while other portion operate turbine in-house electricity production. Mass, energy, balances are applied individual equipment plant. modeled...

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...
