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 transported in liquid form or in vapor form. Transport of the steam mixture through the pipeline is carried out by a centrifugal pump. In order for the pump vanes to be unaffected by wear and to continue their operation without interruption, the mixture must have only a vapor structure. Determine the highest pump fluid pressure value at which the mixture will not form liquid, based on the temperature of the mixture in the pump being 100 °C. The mixture can be well represented by the following activity coefficient model (van Laar model): A₁2 = 2.05 My₁ = Au (1 + Anx.) ² In %1 A21 X₂) A₂1 = 1.50 4/4 x ² A₁2 x₁ In %₂ = A₂ 1+-

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 transported in liquid form or in vapor form. Transport of the steam mixture through the pipeline is carried out by a centrifugal pump. In order for the pump vanes to be unaffected by wear and to continue their operation without interruption, the mixture must have only a vapor structure. Determine the highest pump fluid pressure value at which the mixture will not form liquid, based on the temperature of the mixture in the pump being 100 °C. The mixture can be well represented by the following activity coefficient model (van Laar model): 4₁2 = 2.05 In y₁ = A₁₂ 1+ = diz[14 A₂ = 1.50 A₁2 x₁ A21 X₂ In 7₂ = A21 An ( 1 + Aj X₂ A₁2 X₁ 12
