Simulasi Proses Torefaksi Sampah Sistem Kontinu Menggunakan Software Aspen Plus

ABSTRACT Municipal Solid Waste becomes one of the most unbreakable major problem in cities in Indonesia than other problem. The heat that can be generated from municipal waste reaches 25,2 MJ / kg (6.000 kcal / kg) into one potential alternative energy source to be developed. One development that can be done is to do heat treatment with a solid fuel end product or called torrefaction.The objective of the study was to obtain solid fuel products equivalent to sub-bituminous coal. Developing a laboratory scale system for laboratory waste dumping using a tubular tube, calculates the energy requirement of waste dumping process with 50-80% moisture content in feed waste.The study used ASPENTM simulation software is to simulate the municipal solid waste system laboratory scale process using tubular reactor. The waste system's waste capacity is 5 kg / hour. The simulation system consists of a reactor dryer (Rstoic), reorefaction reactor (RYield), separator and splitsparator. The process of cultivation is retained at 100°C and the torefaction at 275°C occurs continuously on the tubular tube.The simulation results show that the waste water content of the baits has an effect on the energy needs in the drying process and the process of torefaction to the city. Drying energy requirements increased 1,3 kW-3,2 kW on waste water content varation 30- 80%, while solid fuel production reduced about 1,9 kg/hour to 0,5 kg/hour.
