Transesterification of Waste Cooking Oil into Biodiesel Using Aspen HYSYS
Keywords:
Reactive distillation column, waste cooking oil ;biodiesel, Aspen HYSYSAbstract
Increasing uncertainty about global energy production and supply, environmental concerns due to the use of fossil fuels, and the high price of petroleum products are the major reasons to search for alternatives to petrodiesel. Biodiesel fuel has become more attractive because of its environmental benefits, due to the fact that plants and vegetable oils and animal fats are renewable biomass sources. This work presents simulation of an industrial plant for biodiesel production and makes a comparative study of preliminary economic feasibility with a reactive continuous distillation process. The process steady-state simulation was performed using ASPEN/HYSYS 8.0 computer software. Mass and energy balances for each unit, as well as operating conditions, were obtained. The effect of parameters such as molar ratio of methanol to WCO, reflux ratio and reboiler duty on biodiesel mole fraction were investigated.
