Process design and operation III
4 points * 24 lectures, 12 tutorials * First semester * Clayton * Prerequisites: CHE3108, CHE3109
Objectives The student is expected to acquire a basic knowledge and understanding of the use of codes in 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; the further development of the process flowsheet. The student is expected to acquire professional skills in the use of computer packages for design; 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.
