(Process Modelling and Dynamics)
A liquid mixture containing 40.0% benzene (B) and 60% toluene (T) by mass to the distillation column. The upper product stream contains 90 mol% B, and the lower product stream contains 6% of the benzene fed into the column (meaning that 94% of the benzene is left with the upper product). The volumetric flow rate of the feed is 2500 l / hr and the specific gravity of the feed mixture is 0.870.


1- define the problem:
a-Draw the diagram with symbols
b- write the nomenclature
c- Write the assumptions for the process


2- Identify the controlling mechanism for the process


3- Develop a set of model equations (d/dt)
a- Mass balance equation
b- Energy balance equation
