Chemical processes constitute strongly nonlinear systems and for such systems, multiple steady state solutions typically exist. Stability of a chemical process plants is a must concern for every design engineer. This course will include the stability criterions and the methods used such as Routh and Bode Stability criterions. For a stable process the procedure of tuning the parameters have also been discussed here. So this course will really help the aspirants to bulid up a concept for the stability analysis.

It includes all the sensors used for measurement of pressure.

Pressure Measurement

The Laplace Transform (LT) is useful for the study of transient responses of Linear Time Invariant Systems. Model equations are made for the systems to study static gain, rise time, settling time, overshoot and different responses. These model equations are solved using LT. So, we control the dynamics of a system that have parameters changing with time. LT transform the model from time domain to frequency domain.
