(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

c- Component balance equation
