Dynamic Simulation in Chemical Engineering

E-mail Print
In dynamic simulation, natural and chemical phenomena are expressed with algebraic and differential equations based on engineering principles. The mathematical models created are used for analysing how process behaviour varies with time. For the typical case of a process industry, we describe/model the plant subunits and their regulatory control. The relevant equations are solved repeatedly in the time domain and the values of temperature, pressure, flow and composition as well as the valve openings and the process control system output are calculated at every point of interest. Thus, the interactions between the process subunits can become obvious. Further, the process reaction to disturbances (such as feed variation, instruments failure or change of operation strategy) can be fully investigated.
