The understanding of the reaction involved in the transesterification process is important for the design of appropriate reactor for the process. Simulating such process is of primary importance to understanding the parameters that might be required for the design of the reactor. An Aspen-HYSYS simulation was used to determine the condition at which methanol and triglyceride react in a CSTR reactor for optimum yield of methyl ester and glycerol. The model was simulated with variation of parameters to optimize the process and to find an optimum solution. The stoichiometry coefficient used for the design in the ASPEN-HYSYS are -1 for Triglyceride, 2.570 for Methyl ester, 2.50 for Glycol and -3 for Methanol. The simulation was based on 60oC reactional temperature to avoid explosion as the boiling point of methanol is 64.7°C and 15 bar for a CSTR. The heat of reaction obtained from the design is −2.0×105𝐾𝐽/ 𝐾𝑔𝑚𝑜𝑙𝑒. A new design was inferred from the results data obtained. Copyright@ International Science Community Association
