concentration in gas mixture
concentration in gas mixture
(OP)
A centrifufal pump pumps a mixture of acetone and water to an atmospheric tank at 75gpm. Vent gases from this tank are send to an absorber using a blower. under working conditions, I measured solvent ppm and velocity at the blower inlet and calculated scrubbing liquid flow rate required( just for exercise) Now to decrease transfer time, we are planning to pump at 135 gpm to this tank.
how can I calculate flow rate of solvent in the vent gas(to blower) under these conditions??
Appreciate your help for a beginner.

There is outflow too at 90 gpm and the rest overflows to a sump.
At any flow rate, acetone conc in the liquid willl be maintained at 1200ppm(wt). Based on this I can get flow rate of acetone and water in the mixture
If I use boyle's law, PV = constant and using partial pressure of acetone, I can get volume of acetone in the vent gas. I am kinda confused if this calculations are right.

what are the guidelines to determine packed column total height? any references?
