Production of glycerol carbonate using direct carboxyla- tion route suffers from low yield and costly separation units. In contrast, the glycerolysis route using CO2 indi- rectly and urea as a CO2 donor may simplify the glycerol carbonate production, and hence it leads to a more eco- nomical biodiesel-glycerol carbonate production process. Deterministic model predictions show that the net present value of the glycerolysis plant is higher than that of the direct carboxylation plant at the end of 12-year operation. Stochastic model for the economic analysis predicts that the glycerolysis route for glycerol carbonate production increases the probability of getting positive net present value by about 15%.
