CME2029 : Process Measurement, Dynamics & Control

Semesters
Semester 2 Credit Value: 10
ECTS Credits: 5.0

Aims

To gain an appreciation of process measurement devices and control valve sizing.

To gain an appreciation of how time-dependent process behaviour affects the design, operation and safety of process plants.

To learn how to analyse the dynamic behaviour of linear systems and to attain a basic understanding of Chemical Process Control.

This module serves as an introduction to the analysis of linear dynamical systems and basic process control strategies.

Outline Of Syllabus

Measurement of flow, temperature, pressure, level, composition. Control valve sizing.

The importance of dynamic effects; steady-state and non-steady state balances; review of solution of ODEs; the concept of models; the role of dynamic simulation; Laplace Transforms; transfer functions; parameters of transfer functions; transfer function block diagram algebra, typical linear systems responses, linear systems stability and analysis.

Review of open loop dynamics; Closed loop elements; On/off control; PID control; Plant testing for process characterisation; PID tuning; PID loop simulation; Feedforward control; Combined feedback and feedforward control; Cascade control, ratio control; Dead time compensation; Introduction to stability analysis (root locus)
