ABSTRACT
This report presents the design details and economic analysis of a coal-based dimethyl ether (DME) plant. The plant is planned to be built in Peranap, Indragiri Hulu, Riau, Indonesia, due to the abundant coal resources available near the site. The plant is designed to produce 210,000 tons of DME per year, with a coal feedstock requirement of 581,383 tons per year. DME production is focused on meeting market demand for an LPG substitute and reducing LPG imports in Indonesia. The DME market in Indonesia is valued at 9 million USD in 2024, with a growth rate of 22.7% per year, making the construction of a DME plant in Indonesia a potentially profitable investment.
The process used to produce DME is the indirect process. Coal is gasified to produce syngas, which is then fed into a water-gas shift (WGS) reactor to adjust the composition for methanol synthesis. The methanol produced from syngas is then fed into a methanol dehydration reactor to produce DME. The plant requires 83 MW of electrical power, 300 tons/hour of steam, 6,250 tons/hour of cooling water, and 962 tons/hour of refrigerant. The plant's utility system is designed with cogeneration, where power and steam are produced simultaneously. To meet the power requirements, 86,899 tons of coal and 396,761 tons of natural gas per year are needed. Plant waste is treated using the activated sludge process to reduce chemical oxygen demand (COD) and biological oxygen demand (BOD).
The economic analysis shows a total capital investment (TCI) of Rp 7,594,874,954,270 and a total production cost (TPC) of Rp 1,084,861,223,763 per year, with sales amounting to Rp 2,716,178,640,000 per year. The profitability analysis yields a return on investment (ROI) of 16.96%, a payback period (PBP) of 3.46 years, a break-even point (BEP) at 26% production capacity, an internal rate of return (IRR) of 24.28%, and a net present value (NPV) of Rp 616,592,995,946 at a 20% discount rate. The profitability analysis indicates that the coal-based DME plant is feasible and represents an attractive investment.
