| Abstract | The objective is to design the control structures for a smooth biodiesel production from palm fatty acid distillate. Thekinetics of continuous esterification was investigated by considering the following operating parameters: reaction temperature inrange of 50-70 ?C and retention time in range of 10-30 min at a molar ratio of palm fatty acid distillate to methanol of 1:8. Theexperimental results gave the kinetic model as the pseudo-first order in free fatty acid for forward reaction and the second orderin fatty acid methyl ester and water for backward reaction. The design and control of this process were studied also. Conventionaland on-demand control structures with tray temperature control instead of composition control were proposed. Results showedthat both proposed structures could handle changing in the process, ?10% of feed rate change, ?10?C of reactor temperaturechange, and 92-98% free fatty acid content with a satisfiable dynamic performance. |
