Ringkasan Eksekutif Prarancangan Pabrik Metanol Dengan Proses Lurgi-Low Pressure Methanol Dengan Disain Alat Utama Destilasi Metanol
ABSTRACT
Domestic demand for methanol continues to increase, it was recorded that in
2018 Indonesia imported 701,291.5 tons of methanol, which was the highest
import compared to previous years. Methanol is widely used globally for
industrial applications including acetic acid, formaldehyde, MTBE, polyvinyl,
polyester and DME industries. The main raw material used in the manufacture of
methanol with the Low Lurgi Pressure process is natural gas. This factory is
planned to operate for 330 days per year and work continuously for 24 hours /
day with a capacity of 200,000 tons / year which will be established in the
Pelintung Industrial area, Dumai, Riau. The remaining time during the operation
process is used for shutdown, plant maintenance, maintenance and repair of
equipment. The design of the main equipment in this plant is the Methanol
Distillation which functions to separate methanol from water. The distillation
tower is operated at a pressure of 1 Bar and a temperature of 95 ° C. The
economic analysis in this plant design shows that the methanol plant with the
lurgi-low pressure methanol process with the main methanol distillation tool
design is feasible to be established with a BEP value of 41% and a Payback
Period (PBP) 3,008 years factory.
