Module Aims
To introduce the student to the unit operation concept in downstream processing. To develop the theory underlying a range of solid-liquid and heat transfer operations, especially those studied in module BE322. To apply theory to the design, analysis and optimisation of these operations. To further develop problem solving skills acquired in modules BE221, BE222 and BE223.

Learning Outcomes
The student should be able to:* Describe in qualitative terms the principles and mode of operation of a range of solid- liquid and heat transfer processing equipment* Derive simple design equations for solid-liquid and heat transfer operations* Use simple theory as a guide for improving the performance of industrial equipment* Give an account of recent developments in the theory and practice of solid-liquid and heat transfer operations.
