ABSTRACT
The planning of a Dimethyl Ether (DME) plant in Pauh Ranap Village, Peranap District, Indragiri Hulu Regency, Riau Province, focuses on utilizing coal as the primary raw material. Coal from PT. Samantaka Batu Bara-Peranap is chosen due to its sufficient production capacity of 300,138 tons per year to support the planned plant capacity of 210,000 tons of DME per year. The plant's location, approximately 15 km from the coal source, has the potential to reduce distribution costs. However, it is important to note that coal distribution can cause environmental impacts such as NOx, SO2, PM2.5, and mercury emissions. Therefore, selecting a location close to the raw material source is expected to minimize negative environmental effects.
The DME production process uses an indirect method, starting with coal gasification to produce synthesis gas (syngas). The syngas is then sent to a water-gas shift (WGS) reactor to adjust its composition for methanol synthesis. The methanol produced from the syngas is then processed in a methanol dehydration reactor to generate DME. The plant requires 83 MW of energy, 300 tons of steam per hour, and 6,250 tons of cooling water per hour. The plant’s utility system is designed with a cogeneration system that produces both energy and steam simultaneously. To meet its energy needs, the plant requires 86,899 tons of coal and 396,761 tons of natural gas per year. Waste from the plant is treated through an activated sludge process to reduce the chemical oxygen demand (COD) and biological oxygen demand (BOD) in wastewater.
Economic analysis of DME plant from coal with product selling price of Rp. 12,933.33 shows that total capital investment (TCI) is Rp. 7,594,628,874,270 and total production cost (TPC) is Rp. 1,015,157,082,481 per year, with sales revenue reaching Rp. 2,716,178,640,000 per year. The results of profitability analysis show that the payback period (PBP) is 3.46 years, the break-even point (BEP) is at 26% production capacity, the internal rate of return (IRR) is 24.28%, and the net present value (NPV) is Rp. 616,592,995,946 with a discount rate of 20%. Based on these results, this plant project is considered feasible and an attractive investment option.
Keywords: Coal, Dimethyl Etheer, Gasification.
