Definition: This calculator determines the moles of volatile component that can be separated from a non-volatile mixture using steam distillation at equilibrium.
Purpose: It helps chemical engineers and chemists determine the efficiency of steam distillation processes for separating volatile components.
The calculator uses the formula:
Where:
Explanation: The formula calculates how much volatile component will be carried over by steam based on their relative vapor pressures and concentrations.
Details: Accurate calculation is essential for designing efficient separation processes in industries like essential oil extraction, petroleum refining, and chemical manufacturing.
Tips: Enter the moles of steam, mole fraction of volatile component (0-1), vapor pressure of volatile component, and total system pressure. All values must be > 0.
Q1: What is steam distillation?
A: A separation process that uses steam to volatilize and carry over components from mixtures, especially those with heat-sensitive compounds.
Q2: Why does mole fraction range from 0-1?
A: Mole fraction represents the proportion of volatile component in the non-volatile mixture, where 0 means none and 1 means pure component.
Q3: What are typical vapor pressure values?
A: Vapor pressures vary widely but are often in the range of 1,000-100,000 Pa for many organic compounds at distillation temperatures.
Q4: Can this be used for immiscible liquids?
A: The formula is specifically for volatile components mixed with non-volatiles, not for immiscible liquid mixtures.
Q5: How does temperature affect the calculation?
A: Temperature affects the vapor pressure value used in the calculation but isn't directly included in this formula.
