Abstract
Methanol is a chemical compound with a wide range of uses and benefits across various industrial sectors. It is used as an antifreeze coolant, a raw material in the chemical and petrochemical industries, as a solvent in pharmaceuticals and polymers, and as a fuel; consequently, the potential for establishing a methanol plant in Indonesia is quite significant. The plant is scheduled to be operational in 2029 with a capacity of 100,000 metric tons per year at the JIIPE Industrial Park in Manyar Subdistrict, Gresik Regency, East Java. The methanol plant will operate 330 days a year and employ 180 workers. Methanol is produced from natural gas through a metallurgical process that begins by reacting natural gas with steam and oxygen in a combined reformer to produce synthesis gas. The syngas is then reacted in a multitube fixed-bed reactor operating at a temperature of 250°C and a pressure of 50 atm. The reaction in this reactor is reversible and exothermic, with conversion rates of 68% and 3.5%, respectively. The product from the reactor still contains impurities; therefore, a purification process is carried out using a flash drum to separate impurity gases and the methanol-water mixture. Subsequently, the methanol-water mixture is further separated to increase its purity in a distillation column, resulting in a methanol concentration of 99.85% wt.
