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.

sir/mam . I am a fresh student of chemical engineeing. i've somuch fear to face intervies. I become neverse when entered into company. what shall I do? please suggest me some tips to face the interview.
In a triple effect evaporator, the heat transfer for an evaporator is calculated as q = UA (TI – TF) where TI is the initial temperature, TF is the final temperature; U and A are constants. Given that heat transfer for the first evaporator : q(1) = UA (TI – TB); second evaporator : q(2) = UA (TB – TC); third evaporator : q(3) = UA (TC – TF) where q(x) is the heat transfer function, TB is the temperature of second inlet and TC is the temperature of third inlet, prove that the overall heat transfer Q = q(1) q(2) q(3) = UA (TI – TF).

ENGINEERING NUMERICAL METHODS - EXAMPLE 19.2 : For a mixture of benzene (B), toluene (T) and xylene (X), the equation applies where x for B, T and X will sum up to 1. The equation of x for each component is x = (L / V + 1) (F) / (L / V + K). The data of F for each component are : 0.5 for B, 0.35 for T, 0.15 for X. The data of K for each component are : 1.98 for B, 0.76 for T, 0.24 for X. When x for B + x for T + x for X = 1, find the values of (a) L / V; (b) x for each component of B, T, X respectively. You may use Excel program - Data : What-If-Analysis for Goal Seek to perform the iterative calculations.
ACCOUNTING AND FINANCIAL ENGINEERING - EXAMPLE 34.31 : In a biochemical engineering company, let the actual revenue generated = A, actual cost incurred = B. According to the standard budget, the revenue generated = C, cost incurred = D. (a) Find the profit according to : (i) actual situation; (ii) standard budget. (b) Calculate the Variance Due to Price and Efficiency in : (i) revenue generated; (ii) cost incurred; (iii) profit. (c) If E > F where > represents : more than, find the 4 pairs of values of E and F in favorable conditions.
CHEMICAL ENERGY BALANCE - EXAMPLE 11.3 : For liquid benzene, the CP constants are : a = 129440, b = - 169.5, c = 0.64781. Reference temperature is 298 K. The temperature of benzene is 60 degree Celsius. Calculate the enthalpy of benzene by using the formula H = a (DT) + (b/2) (T^2 - TREF^2) + (c/3) (T^3 - TREF^3) where ^ is power, DT is temperature difference with TREF = 298 K. H is in J / kmol. DT = T - TREF.
ACCOUNTING AND FINANCIAL ENGINEERING - EXAMPLE 34.8 : Cash flow agreement where the sign + or - of the amounts are start negative and at a point switch to positive and stay positive is referred to has an investment. The cash flow could be denoted by the symbol of [a, b, c ...]. Consider the following two cases in a biochemical factory : (a) You pay $1 today. You receive $1.05, one year from now. (b) You pay $3 today. You receive $5, one year from today. You pay $2, two years from today. Determine if cases (a) and (b) are an investment or a business transaction with cash flow symbol. Find the interest rate r in the cash flow in both cases (a) and (b).
