Instrumentation and Process Control in Petrochemical plant

: At the end of this course, the students should be able to: 1. explain the basic principles and importance of process control in industrial process plants; 2. specify the required instrumentation and final elements to ensure that well-tuned control is achieved; 3. explain the use of block diagrams and the mathematical basis for the design of control systems; 4. explain different control modes and their application in controlling various processes; 5. explain the working of electric, hydraulic and pneumatic controllers; 6. demonstrate the workings and application of the different types of actuators and control valves; 7. explain the importance and application of good instrumentation for efficient design of process control loops for process engineering plants; and 8. draw a PID (Process and Instrumentation Diagram) and devise simple but effective plant wide control strategies using appropriate heuristics. * The students should learn how to use instrumentation software, (LABVIEW, PDMS) Scilab (is a numerical computation package that is very important in instrumentation and control engineering.) to solve problems exposed to them in the
