CHE4109

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.
