The plug flow reactor (PFR) model is used to describe
chemical reactions in continuous, flowing systems. The PFR
model is used to predict the behaviour of chemical reactors,
so that key reactor variables, such as the dimensions of the
reactor, can be estimated. PFR's are also sometimes called
Continuous Tubular Reactors (CTR's).

An ideal continuous stirred-tank reactor is based on the
assumption that the flow at the inlet is completely and
instantly mixed into the bulk of the reactor. The reactor
and the outlet fluid have identical, homogeneous
compositions at all times. An ideal CSTR has an exponential
residence time distribution:

ENGINEERING MATHEMATICS - EXAMPLE 8.4 : Let 1 ^ 1 = 1, 2 ^ 2 = 4, 3 ^ 3 = 27. By using the Excel computer programming - either by Solver or Goal Seek, find the value of v for the Van der Waals equation (P - a / v ^2) (v - b) = RT where a = 18.82, b = 0.1193, P = 2, R = 0.082, T = 5000 for benzene. Describe briefly how to use Solver and Goal Seek in Excel program of computer to find the solution quickly.

CHEMICAL ENERGY BALANCE - EXAMPLE 11.1 : Please match the term A - E with the stated definition i - v. Terms : A. Yield. B. Selectivity. C. Relative saturation. D. Molal saturation. E. Absolute saturation. Definitions : i. (moles of desired product formed) / (moles that would have been formed if there were no side reactions and the limiting reactant has reacted completely); ii. (moles of desired product formed) / (moles of undesired product formed); iii. (relative humidity 40 % means partial pressure of water vapour equals 4 / 10 of the vapour pressure of water at the system temperature); iv. (moles of vapour) / (moles of vapour dry gas); v. (mass of vapour) / (mass of dry gas).
