The subject
What Process Design & Control covers
This course covers the mathematical operations associated with process design, beginning with the theoretical background of Laplace transforms and moving into practical implementation. System stability and response are explored through first and second order systems, with higher order systems covering poles and zeros, time delays and inverse responses. Process control methods are covered extensively, including feedforward, feedback, cascade and ratio control, alongside analysis of temperature profiles in relation to system disturbances. A range of costing methods is detailed to support the industrial application of real process design principles, and process safety is considered as part of designing safe and efficient processes. Learners come away able to solve and use Laplace transforms between the time and s domains; understand system responses and stability across different order systems; implement control systems for industrial case studies with a focus on controlled and manipulated variables; apply control schemes to closed loop systems including modelling, set-point changes and block diagram construction; and understand the costing methods used to estimate process costs.
What you’ll be able to do
- Explain why capital and operating costs precede project authorisation
- Contrast bottom-up with top-down control design procedures
- Explain why Laplace transforms are used to solve process control equations
- Recognise higher order denominators and numerator dynamics in transfer functions
- Determine closed-loop response to a set-point change
- Order plantwide control design by setting material flows before quality loops
