Batchwise and Semibatch Processing 5 (U00355)

? Credit Points : 10 ? SCQF Level : 11 ? Acronym : EEL-5-CHBAT

This module reviews types of batch processes and industries where they are employed. It covers equipment used in and scheduling of batch processes. Topics presented in detail include: unsteady state reaction and heat transfer, fluid mechanics in agitated vessels, batch distillation, absorption and filtration.

Hazards associated with batch processes and the hazard and operability analysis for a batch plant are discussed. There will be a works visit to a local fine chemicals plant at which various types of equipment used in this industry will be exhibited.

Summary of Intended Learning Outcomes

Students should be able to:
- choose between batchwise and continuous operation for a process;
- find overall cycle times using a Gantt chart, identify and eliminate bottlenecks;
- determine reactor cycle time contributions from charge and discharge, heating and cooling, and reaction time;
- design agitators, heat transfer equipment and absorbers;
- design and schedule batch distillation columns;
- select and size filters for batchwise operation;
- conduct hazard studies for plants (including batch plants) with high material holdups and non-steady state operation.
