Answer / ramana reddy

distillation columns are operated at different feed rates
as well as different steam pressures, but distillation
towers are operated at stedy state conditions only (
constant reflux, stem, feed )

Answer / tauseef

column has no inside space bcz it is completely solidy like
during construction civil engineer make concrete column
while tower has a inside space..like FL tower, IT tower...

regarding chemical engineering
in column reflux is used to increase the purity of overhead
product
while in tower no reflux is used.

In a Laplace Transform Table, the Laplace transfer function of f(t) is F(s). When d(t) = f(t) then 1 = F(s). When x(t) = f(t) then X(s) = F(s). If d(t) is the impulse of a spring when d(t) = kx(t), then derive the equation for the impulse of a spring as X(s) in term of k. Next question : A controller has a transfer function a and the other controller has a transfer function b. The overall transfer function of both controllers is ab. What is the transfer function overall when both controllers have similar transfer function 1 / (Cs k)?

REACTION ENGINEERING - EXAMPLE 13.3 : The half-life for first order reaction could be described in the differential equation dC / dt = -kC where k is a constant, C is concentration and t is time. (a) Find the equation of C as a function of t. (b) Find the half life for such reaction or the time required to reduce 50 % of the initial concentration, where k = 0.139 per minute. (c) When the initial concentration Co is 16 mol / cubic metre, how long does the reaction required to achieve the final concentration of 1 mol / cubic metre?
