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.

CHEMICAL ENERGY BALANCE - EXAMPLE 11.5 : According to Margules Equation, P = x(1) p(1) g(1) + x(2) p(2) g(2) for a two-component mixture where P is bubble pressure, x is mole fraction, p is saturation pressure, g is constant given by ln g(1) = x(2) A x(2). Find the value of A as a constant when P = 1.08 bar, p(1) = 0.82 bar, p(2) = 1.93 bar in a 50 : 50 mole fraction mixture. Estimate the pressure required to completely liquefy the 30 : 70 mixture using the same equation, by proving P = 1.39 bar. Take note that ln g(2) = x(1) A x(1), ln g(1) = x(2) A x(2).
