ABSTRACT
The national demand for Ethyl Tertiary Butyl Ether (ETBE) as an environmentally friendly fuel additive continues to increase, while domestic needs are still entirely met through imports, amounting to 238.4 tons per year (BPS, 2023). To reduce dependency on imports and to optimize the utilization of agricultural waste, an ETBE plant is designed with a production capacity of 90,000 tons per year, using bioethanol and isobutene derived from oil palm empty fruit bunches (EFB). The choice of EFB is based on its abundant availability in Riau Province and its high lignocellulosic content that can be processed into high-value compounds. The plant is planned to be built in Basilam Baru Village, Sungai Sembilan District, Dumai City, Riau Province, on a land area of 121.29 hectares. This location was chosen due to its proximity to raw material sources and access to transportation infrastructure such as ports, highways, and airports.
The ETBE production process begins with biomass pretreatment and fermentation of hemicellulose (C5) and cellulose (C6) to produce ethanol, followed by additional fermentation for isobutene synthesis. The etherification reaction between ethanol and isobutene is carried out in two reactors operating under isothermal and adiabatic conditions using Amberlyst-15 as a catalyst. The resulting product is purified using a hybrid process of distillation and pervaporation membrane technology to overcome the azeotropic separation challenge between ethanol and ETBE, resulting in a product with 99% purity. The utility system is supported by a cogeneration power plant fueled by methane generated from anaerobic digestion of liquid waste, producing 130.09 MW of electricity and three types of steam (1, 5, and 15 bar). The total electricity demand reaches 53,510.02 kW, and the total water demand is 1,103,950.68 kg/hour, sourced from the Geniot River and treated through an integrated water treatment system. Process safety and control systems are designed according to chemical industry standards to ensure operational sustainability and safety.
Economic analysis shows that the project is feasible, with a Net Present Value (NPV) of Rp 18.186.484.461.458, an Internal Rate of Return (IRR) of 28%, a Payback Period (PBP) of 3.25 years, a Return on Investment (ROI) of 28%, and a Break-Even Point (BEP) at 22,55% plant utilization.
