The continuous support and generosity of my supervisors, Assoc. Prof. Moses O. Tade, Prof. Terry N. Smith and Prof. Ravi Datta, was received with gratitude at all times. The exceptional technical skills of Mr. Colin Glassen and the assistance of many members of the technical staff at Curtin were crucial during the construction of the reactive distillation pilot plant and were greatly appreciated. The contribution of numerous and unknown reviewers was also significant, and their detailed comments, compliments and criticisms added considerably to the completed work. Finally, the support and understanding of my girlfriend and confidant, Creenagh Bond, is acknowledged with the warmest thoughts and respect.
