WebJan 1, 2009 · A transient flowsheeting will be required to work in a real-time environment. The simulation is run concurrently with an optimization program to obtain the optimum moves in the manipulated variables. The question may arise what changes would intrude the flowsheeting structure if the transient state of the process had to be considered. WebSep 5, 2016 · Flowsheeting. However it is enough to say that if we consider a flowsheet we identify numerous information: i.e. A shape specifies a model.
