1) Immiscible Liquid-Liquid Extraction: A feed of 10,500 kg/hr consists of 12 wt% acetic acid in water. The removal of acetic acid is to be accomplished by liquid-liquid extraction in water at 25°C. The raffinate is to contain no more than 1 wt% acetic acid. K The following four solvents (and accompanying distribution coefficients are being considered. Water and each solvent can be considered immiscible. SOLVENT Methyl acetate 1.253 Isopropyl ether 0.929 Heptadecanol 0.612 For each solvent, estimate the flow rate (kg/hr) if a single equilibrium stage is used to achieve the desired separation. Chloroform 0.578 Discuss the solvent choices and indicate which may be the best option.

Question
### Immiscible Liquid-Liquid Extraction #### Overview: A feed of 10,500 kg/hr consists of 12 wt% acetic acid in water. The removal of acetic acid is to be accomplished by liquid-liquid extraction in water at 25°C. The raffinate is to contain no more than 1 wt% acetic acid. #### Solvent Options: The following four solvents and their distribution coefficients (\(K\)) are being considered. Note that water and each solvent can be considered immiscible. | Solvent | K | |------------------|--------| | Methyl acetate | 1.253 | | Isopropyl ether | 0.929 | | Heptadecanol | 0.612 | | Chloroform | 0.578 | #### Calculation Requirement: For each solvent, estimate the flow rate (kg/hr) if a single equilibrium stage is used to achieve the desired separation. #### Discussion: Evaluate the solvent choices and indicate which may be the best option. --- This setup would be suitable for an educational website, providing students or learners with straightforward information on performing liquid-liquid extraction using given solvents and distribution coefficients. Discussion points could include criteria for selecting the best solvent, such as distribution coefficients, cost, toxicity, and environmental impact.
