Rancangan Pabrik Alpha Olefins Proses Alpha Sablin dengan Desain Alat Utama Kolom Distilasi 1-Butena

Alpha Olefins are linear hydrocarbons with a double bond at the alpha position, such as 1-Butene, 1-Hexene, and 1-Octene. The production of Alpha Olefins is considered a basic chemical product because they are used as raw materials for the production of other chemicals. In Indonesia, Alpha Olefins are used as comonomers for the production of Linear Low-Density Polyethylene (LLDPE) and High-Density Polyethylene (HDPE). The production of LLDPE requires 10% of Alpha Olefins comonomers (C4-C8), while HDPE requires 4% of Alpha Olefins comonomers (C4-C6). Currently, Indonesia's demand for Alpha Olefins is met through imports, as they are not produced domestically. The establishment of an Alpha Olefin plant will reduce the need for imports and increase national revenue. The Alpha Olefin plant is planned to be built in Ciwandan Subdistrict, Cilegon City, Banten Province, in 2024, with a production capacity of 58,000 tons per year.
The process used to produce Alpha Olefins involves the oligomerization of ethylene using toluene as a solvent, zirconium (IV) silicate (ZrSiO4) as a catalyst, and trimethylaluminum (Al(CH3)3) as a co-catalyst. The reaction takes place at an operating temperature of 80°C and a pressure of 30 bar, yielding 1-Butene, 1-Hexene, and 1-Octene as the main products. The plant’s electricity needs are met by a turbine driven by steam. Water requirements are fulfilled through seawater desalination via reverse osmosis. Liquid waste from the laboratory, maintenance, and domestic sources is treated using Tertiary Treatment, which includes filtration, activated sludge, and chemical processing. Hazardous waste (B3) from deactivated catalysts is managed by a third party, PT Krakatau Steel WWTP. The plant is designed with a Heat Exchanger Network (HEN). Equipment in the plant is equipped with safety instruments and process control instruments to ensure process performance, stability, and minimize external disturbances. The main tool design in this design is a 1-butene distillation tower which functions to separate 1-butene from the mixture. The type of distillation column used is the tray column. The operating conditions on the distillation column are 187.85 °C with a pressure of 9.89 bar.
The Alpha Olefin plant operates 347 days per year and 24 hours per day. The plant runs for 47 weeks per year, with 3 weeks allocated for shutdown, maintenance, and repairs. The company is established as a Private Limited Company (LTD) with types of functional organizational structures and employs 131 personnel. Based on the economic analysis, the Alpha Olefin plant is feasible for construction, with a Discounted Payback Period of 4.78 years, an Internal Rate of Return of 24.29%, a Break-Even Point of 35.36%, and a Net Present Value of Rp10,006,357,284,476.
