Process design and operation III

4 points
* 30 lectures and 6 tutorials
* First semester
* Clayton
* Prerequisites: CHE3108, CHE3109

Objectives The student is expected to acquire a basic knowledge and understanding of the mechanical design of pressure vessels and structural supports; the types and operating characteristics of columns available for gas- liquid contacting; the use of heat exchanger networks to effect energy conservation; and the further development of the process flowsheet. The student is expected to acquire professional skills in the use of computer packages for design and the quantitative analysis (`Hazan') of the safety risks which must be considered in the operation of process plants.

Synopsis Mechanical design of pressure vessels, design of structural supports and foundations, use of relevant codes; selection and design of packed and tray columns for gas - liquid contacting, hydraulics of trays and packings, specification of column internals; hierarchy of design and heuristic approach to flowsheet development, sequencing of distillation columns; use of CAD packages such as PRO/II, ASPEN and HYSIM; heat exchanger network analysis; plant layout; quantitative risk assessment for safety hazards; retrofit design of plant and processes.

Assessment Examination: 70%
