In a chemical production facility, a mixture containing 80% acetone and 20% water by mol will be transported through the pipeline. This mixture can be in liquid or vapor form. It can be transported. a) Transport of the liquid mixture through the pipeline is carried out by a piston pump. This pump locks and automatically stops its operation if the mixture contains any steam. If the liquid mixture temperature is 100°C, determine the minimum pressure value at which the pump must operate smoothly (in such a way that the mixture does not contain steam). b) Transport of the vapor mixture through the pipeline is carried out by centrifugal pump. In order for the pump vanes to be unaffected by wear and to continue their operation without interruption, the mixture must be only in vapor form. If the mixture in the pump is at a temperature of 100 °C, determine the highest pump fluid pressure value at which the mixture will not form liquid. The mixture is well represented by the van Laar activity coefficient model with parameter values A12 = 2.05 and A21 = 1.50.

Question
Transcribed Image Text:In a chemical production facility, a mixture containing 80% acetone and 20%
water by mol will be transported through the pipeline. This mixture can be in liquid or vapor form.
It can be transported.
a) Transport of the liquid mixture through the pipeline is carried
out by a piston pump. This pump locks and automatically stops its operation
if the mixture contains any steam. If the liquid mixture temperature is 100°C,
determine the minimum pressure value at which the pump must operate smoothly
(in such a way that the mixture does not contain steam).
b) Transport of the vapor mixture through the pipeline is carried out by
centrifugal pump. In order for the pump vanes to be unaffected by wear and to
continue their operation without interruption, the mixture must be only in
vapor form. If the mixture in the pump is at a temperature of 100 °C, determine
the highest pump fluid pressure value at which the mixture will not form liquid.
The mixture is well represented by the van Laar activity coefficient model with
parameter values A12 = 2.05 and A21 = 1.50.
