Abstract: Based on the scale-up of laboratory experiment, the Superpro Designer? emluator was applied to simulate the whole process of supercritical methanol production technology for 50000 t/a biodiesel production, coupled with costing and economic evaluation on the flowsheet. Simulation results indicate that the process design is reasonable with main process data complying with experimental results. The economic analysis shows that high temperature and high pressure equipment shares larger proportion of equipment purchase cost, and raw materials cost is more than 70% of operating cost, this technology has good feasibility as the after-tax profit is about 27.04 million yuan per year with the project total investment of approximately 72.72 million yuan.

Key words: biodiesel, supercritical methanol, process simulation, economic analysis
