In this study, design of biodiesel production process from waste cooking oil through supercritical and subcritical processes with co-solvent methods was studied. The processes with production capacity of 10,000 tons a year were designed and simulated using the simulation software Aspen Plus. Simulation results showed that both processes can provide purity of fatty acid methyl ester as biodiesel standard. Furthermore, economic analysis was performed using Aspen Process Economic Analyzer. Results showed that the subcritical with co-solvent process is more economically promising, that is, the process has lower capital cost, lower payout period, and higher internal rate of return.
