A Novel Biodiesel and Glycerol Carbonate Production Plant

Nghi T. Nguyen / Yaşar Demirel
Published Online: 2011-11-16 | DOI: https://doi.org/10.2202/1542-6580.2856

Crude glycerol is the byproduct of biodiesel production plant and the economic value of glycerol may affect the profitability of the biodiesel production plant. As the production rate of bioglycerol increases, its market values drop considerably. Therefore, conversion of bioglycerol into value-added products can reduce the overall cost, hence, leading to a more economical biodiesel production plant. In a direct carboxylation reaction, CO2 reacts with glycerol to produce glycerol carbonate and water. This study presents a direct comparison of the economic analysis of the conventional biodiesel production plant and the possible next generation biodiesel-glycerol carbonate production plant. At the end of 15-year project, the net present value of the biodiesel-glycerol carbonate production plant is $13.21 million higher than the conventional biodiesel plant. The stochastic model has predicted that the biodiesel-glycerol carbonate and conventional biodiesel production plants has about 30% and 63% chance of getting negative net present value, respectively. Heterogeneous catalyst, Ca3La1, is used for transesterification reaction to reduce separation steps in the biodiesel production process.

Keywords: biodiesel; carboxylation of bioglycerol; n-dibutyltin(IV)oxide; heterogeneous catalyst; glycerol carbonate; economic analysis
