study the behavior of any process‚ the first step is to make the flow sheet converged in steady state so as to define and obtain the characteristic of the process. Once this flow sheet is converged‚ then it is imported to Aspen plus Dynamics so as to control and study nonlinearity of the system. Simulation of TAEE etherrification is carried out in Aspen Plus. Firstly‚ the reactive distillation column is simulated by the module‚ RadFrac‚ using NRTL property method. For this purpose‚ ASPEN PLUS requires

Management last week‚ a transmitter is a tool which usually installed in the controller‚ which use to transfer the data from the field-site indicator to the control room‚ let say we use a Distributed Control System (DCS). Then‚ based from the data gathered an action might be needed to optimize the well performance‚ this is when the Final Control Element (FCE) come in handy. Of course there is some mathematical model needed to be generated to transfer those data into valuable information‚ but without
