Abstract
AbstractThe biodiesel production catalyzed by naturally derived catalysts such as calcium oxide (CaO) and sulfonated carbon catalysts achieved high biodiesel yield at moderate operating conditions. However, very few studies were conducted to evaluate the economic feasibility of industrial‐scale production of biodiesel catalyzed by both green catalysts of CaO and sulfonated carbon catalysts. The current study aims to assess the technical competency and economic feasibility of industrial‐scale production of biodiesel catalyzed by two processes 1.) CaO catalyst and 2.) sulfonated carbon catalyst. Process simulations via Aspen Hysys were carried out to perform material and energy balances for both process configurations designed earlier with respect to the base catalyst (CaO) and acid catalyst (sulfonated carbon) used. Economic analysis was initiated after the equipment sizing and costing had been carried out. Total capital investment, total manufacturing cost, and key performances of the rate of return, payback time, breakeven point, and net profit after‐tax rate were calculated for each process. Based on the economic analysis, the computed return on investment (ROI) is 105.36%, and it has a low payback period of 0.94 year to offset its original investment. The discounted cumulative profit (NPV) analysis shows that breakeven was achieved in the 3rd year. On the other hand, for the plant that utilizes sulfonated carbon in the transesterification reaction, the computed ROI is 14.02% with a payback period of 7.13 years, and the breakeven was achieved in the 9th year. In conclusion, the manufacturing plant of transesterification reaction catalyzed by CaO catalyst appeared as the most promising pathway either technically or economically.
