Answer / amal raj

anywhere position the pump no problem

Answer / gohil

Position of Pump - Generally at Ground Level. (Pump to meet
NPSH Requirement)
Position of Reflux Drum and Condenser depend on Type of
Pressure Control System used for column pressure control and
type of heat exchanger (condensor) i.e.partially or total
flooded.

Answer / kashif

I Have installed Reflux Pumps at 0.0mtrs Ground Level While
Reflux Pot is at 5.0 mtrs Level and condensors are at 13.5
mtrs Level ,its Working Satisfactory.
While in another case reflux Pot is at 5.0mtrs and
condensor is at 10.0mtrs and Reflux Pumps are at Ground
0.0mtrs Level. This column is used for Methanol
Distillation.

Answer / jayesh

Heat transfer: In a steady state one dimensional conduction with no heat generation, the differential equation is d / dx (k dT / dx) = 0. Prove that T(x) = ax b, where k, a and b are constants. (b) At x = 0, T = c and at x = L, T = d. Prove that T(x) = (d - c) x / L c for boundary conditions.

CHEMICAL ENERGY BALANCE - EXAMPLE 11.2 : Calculate the cooling duty, H required to condense and cool acetone from 100 degree Celsius to 25 degree Celsius at atmospheric pressure. The heat of vaporization for acetone at its normal boiling point is 30.2 kJ / mol. The boiling point of acetone at atmospheric pressure is 56 degree Celsius. The flowrate of acetone through the condenser is 100 mol / s = N. Value of sensible heat needed to increase the temperature of acetone in liquid form from 25 to 56 degree Celsius is 4.06 kJ / mol. Value of sensible heat needed to increase the temperature of acetone in vapor form from 56 to 100 degree Celsius is 3.82 kJ / mol. Unit of H is kJ / s.
