In this study we present advanced mathematical model was used to capture the batch reactor characteristicsof reacting compounds new parameters and new a prerequisite average slope analysis (PASA) methodfor the system dynamic behaviour under different operational conditions is a prerequisite to the good selectionfor these parameters. The model was applied to batch reactor for the production of bio-diesel from palmand kapok oils. Results of the model were compared with experimental data in terms of conversion oftransesterification reaction for the production of bio-diesel under unsteady state. A good agreement wasobtained between our model predictions and the experimental data. Both experimental and modeling resultsshowed that the conversion of triglycerides to methyl ester was affected by the process conditions andby using PASA that could be achieved by making some deterministic tests either in real data plant or in thephysical model that properly and adequately fits the actual process. The input-output relationships arestudied using the open-loop dynamic response of the process, which can be determined from the processmodel by stepping different inputs and recording output responses. Starting from steady state conditions,each input is perturbed with certain magnitude that is enough to show the effect on the system dynamics.The transesterficition process with temperature of about 70 oC, and methanol ratio to the triglyceride ofabout 5 times its stoichiometry and the NAOH catalyst of wt 0.4%, appear to be acceptable process conditions.PASA shows methanol ratio to the triglyceride has big effect on the system. PASA method can be appliedfor different processes |
