Abstract

Penelitian ini bertujuan untuk menentukan parameter proses optimum untuk menghasilkan biodiesel dengan yield tinggi dari minyak jelantah melalui metode transesterifikasi metanol superkritikal, serta mengevaluasi kelayakan teknis dan ekonominya. Proses disimulasikan menggunakan perangkat lunak Aspen HYSYS dengan pendekatan reaktor Plug Flow Reactor (PFR). Berbagai parameter seperti temperatur, tekanan, rasio methanol to oil, dan penggunaan katalis dianalisis untuk menemukan kondisi optimum. Hasil simulasi menunjukkan bahwa kondisi optimum dicapai pada suhu 280°C, tekanan 100 bar, rasio methanol-to-oil 5:1, dengan katalis KOH, yang menghasilkan yield biodiesel sebesar 98,15%. Neraca massa menunjukkan kesesuaian konversi dengan perhitungan teoritis. Analisis energi menunjukkan konsumsi energi terbesar berasal dari kolom distilasi sebesar 6.225 kW. Namun, energi output dari biodiesel yang dihasilkan mencapai 12.723 kW setelah dikonversi menggunakan generator diesel berefisiensi 25%, menghasilkan net energy gain sebesar 5.103 kW. Dari sisi ekonomi, plant biodiesel dengan katalis KOH berkapasitas 5.000 kg/h yang beroperasi 8.000 jam per tahun menunjukkan kelayakan finansial dengan Net Present Value (NPV) sebesar 18,8 juta USD, Internal Rate of Return (IRR) sebesar 16%, Break-Even Point (BEP) dalam 3,64 tahun, dan rata-rata Benefit to Cost Ratio (BCR) sebesar 1,72. Analisis sensitivitas menunjukkan bahwa yield minimum agar proyek tetap menguntungkan secara finansial adalah 85%.

This study aims to determine the optimal process parameters for producing high-yield biodiesel from waste cooking oil through the supercritical methanol transesterification method, as well as to evaluate its technical and economic feasibility. The process was simulated using Aspen HYSYS software with a Plug Flow Reactor (PFR) model. Various parameters, such as temperature, pressure, methanol-to-triglyceride ratio, and the use of KOH catalyst were analyzed to identify the optimal conditions. Simulation results show that the optimal condition is achieved at 280°C, 100 bar, a methanol-to-oil molar ratio of 5:1, with KOH as catalyst, resulting in a biodiesel yield of 98.15%. The mass balance indicates a strong agreement between theoretical and simulated conversion. Energy flow analysis reveals that the distillation column accounts for the highest energy consumption at 6,225 kW. However, the energy output from the produced biodiesel reaches 12,723 kW after being converted using a diesel generator with 25% efficiency, resulting in a net energy gain of 5,103 kW. From an economic perspective, a KOH catalyst biodiesel plant with a capacity of 5,000 kg/h operating 8,000 hours per year is financially feasible, with a Net Present Value (NPV) of USD 18.8 million, an Internal Rate of Return (IRR) of 16%, a Break-Even Point (BEP) of 3.64 years, and an average Benefit to Cost Ratio (BCR) of 1.72. Sensitivity analysis shows that a minimum yield of 85% is required for the project to remain financially viable.
