Prarancangan Pabrik Dimetil Eter Dari Tandan Kosong Sawit (Tks) Menggunakan Proses Indirect Synthesis Dengan Disain Alat Utama Reaktor Dme
ABSTRACT
The need for renewable energy increases with the number of business and process
that require biogas and dimethyl ether as the raw material in the manufacturing
process. Dimethyl ether is widely used as refregerant, propellant in aerosol
products, solvent, and extraction agent. The main raw materials used in
manufacture of dimethyl ether by indirect synthesis process is palm empty fruit
bunch. This plant is planned to operate for 330 days per year and work
continuously for 24 hours/day with capacity of 50,000 ton/year which will be
established in Dumai, Riau. The remaining time for 1 year of the operation
process is used for shutdown, plant maintenance, maintenance and repair of
equipment. The design of the main equipment in this plant is Dimethyl Ether fixed
bed reactor which functions to generate dimethyl ether by methanol dehydration
process. Reactor is operated at a pressure of 5 Bar and a temperature of 250 °C.
The economic analysis on the design of this plant shows that the dimethyl ether
plant from palm empty fruit bunch is feasible to be established with the profits
that the plant gets after tax is Rp. 1,807,080,722/year and the plant's Payback
Period (PBP) is 2.29 years.
