ABSTRACT
Dimethylacetamide (DMAc) is a highly important organic solvent widely used in the pharmaceutical, textile, and plastic industries due to its excellent thermal stability, high purity, and superior solvent properties. The demand for DMAc in Indonesia has continued to grow annually; however, the supply is currently fully dependent on imports. This presents a significant opportunity for Indonesia to produce DMAc independently and emerge as a regional manufacturer. The DMAc plant is planned to be established in Purwakarta District, Cilegon City, Banten Province, in 2028 with a production capacity of 70,000 tons per year.
PT DaiNusa Chemical will produce Dimethylacetamide (DMAc) using raw materials dimethylamine and acetic acid, based on patented technology from DuPont (US3300531). The production process consists of two main stages: amidation reaction using Fe₃O₄ catalyst in a bubble column reactor, and a subsequent separation and purification stage via two distillation towers (T-101 and T-102). The main product, DMAc with 98% purity, is collected from the bottom of T-101, while acetic acid and water are separated and recycled through T-102. To support continuous operations, the plant is equipped with utility systems including a steam generation unit (natural gas-fired water tube boiler), water supply unit (sourced from the Cidanau River), and power supply unit. Process control in the DMAc plant involves instrumentation systems comprising sensors, indicators, controllers, recorders, and safety devices such as alarms.
Economic analysis results show a Total Capital Investment (TCI) of IDR 3,398,059,342,046, a Total Production Cost (TPC) of IDR 2,254,478,401,358, and a Working Capital Investment (WCI) of IDR 509,708,901,307. Profitability analysis indicates a Net Present Value (NPV) of IDR 5,590,892,011,804, with an Internal Rate of Return (IRR) of 22.43%. The Break-Even Point (BEP) occurs at 54.49% production capacity, and the Payback Period (PBP) is 2.82 years. These results demonstrate that the DMAc plant is feasible and represents a profitable investment opportunity.
Keywords: Economic feasibility analysis, DMAc, Plant Design, Sensitivity, Utilities.
