Simulasi Proses Torefaksi Sampah Sistem Kontinu Menggunakan Software Aspen Plus

Abstract

The heating value of solid fuels obtained from torrefied MSW reaches 6,000 kcal/kg so that it has the potential to replace coal. The challenge faced today is how to develop a continuous reactor system to get solid fuel from torrefied MSW. The objective of this study is to simulate torrefaction process using ASPEN TM software on a continuous system with a tubular reactor. MSW feed capacity of 5 kg/hr with variation of moisture content about 30-80%. The simulation system consists of a drying reactor (Rstoic), a reactor of torefaction (RYield), a separator and a splitsparator. The drying process retained at temperature 100°C and torefaction temperature at 275°C, occurring continuously on the tubular reactor. The simulation results show that the mosture content content of MSW has significant effect on the energy requirement in the drying and torefaction process. The energy required for torefaction increased by about 1.6 kW to 3.4 kW in a 30-80% moisture content variation, while solid fuel production decreased by about 2.1 kg/hr to 0.6 kg/hr

Peningkatan Kualitas Briket Ampas Kopi Menggunakan Perekat Kulit Jeruk Melalui Metode Torefaksi Terbaik

“…Torefaksi bertujuan untuk meningkatkan nilai kalor biomassa agar setara dengan batubara [4]. Keunggulan proses torefaksi adalah temperatur dan tekanan yang digunakan relatif rendah dibanding dengan teknologi lain, serta efisiensi konversi energi cukup tinggi hingga 90% [5].…”

Simulasi Kenaikan Kapasitas Produksi Gula Pada Proses Karbonatasi Di Pt. Industri Gula Glenmore Menggunakan Perangkat Lunak Aspen Plus

“…Hal ini disebabkan karena adanya kenaikan massa pada setiap proses. Kenaikan energi akan sebanding dengan kenaikan massa yang terdapat dalam suatu reaksi (Amrul, Triyadi, & Gandidi, 2019;Muharja et al, 2019). Hasil perhitungan mengalami perbedaan antara spreadsheet dan Aspen plus, Hal ini disebabkan karena perhitungan evaluasi dengan proses simulasi menggunakan kondisi ideal sedangkan kondisi dilapangan tidak ideal.…”
