Perancangan Pabrik Dimethyl Ether (DME) Dengan Bahan Baku Gas Alam Andaman Dengan Desain Alat Utama DME Reactor (R-102)

ABSTRACT
Indonesia's demand for LPG is projected to increase by up to 2.7 times by 2050, with only one-third of the demand met by domestic production. Andaman natural gas, with a feed of 182,249.96 tons/year, is utilized as a raw material to produce 200,000 tons/year of Dimethyl Ether (DME). Methane from Andaman natural gas is converted into synthesis gas (syngas) and subsequently synthesized into DME. The plant is planned to be built in Lhokseumawe City, Aceh, Indonesia, chosen for its proximity to the natural gas source from Andaman. DME has the potential to supplement or replace LPG due to its similar properties to propane and butane, with a heating value of 20.5 MJ/kg. Syngas production from natural gas employs the methane tri-reforming (MTR) process, which combines steam reforming, dry reforming, and partial oxidation of methane, achieving 99.99% CH₄ conversion and an H₂/CO product ratio of 1.43—an optimal ratio for direct DME synthesis. DME synthesis is carried out using a direct synthesis process simulated in a plug flow reactor (PFR), achieving 78.91% methanol conversion with 99.42% overall methanol conversion. Unconverted methanol is reprocessed in a reactive distillation column (RDC) while simultaneously purifying DME to 99% concentration. CO₂ produced from the direct synthesis process is recycled back into the MTR feed, with the remainder processed as a byproduct in the form of liquefied CO₂ amounting to 7,670.44 tons/year. Profitability analysis parameters—NPV, ROI, PBP, IRR, and BEP—are valued at Rp 919,103,136,403.66; 33.02%; 1.96 years; 22.71%; and 24%, respectively, under the assumption of constant raw material and product prices.
Keywords: Economic Analysis, Dimethyl Ether, Plant Design, Sensitivity, Utilities.
