Data Source and Methodology
Tutti i calcoli si basano rigorosamente sulle formule e sui dati forniti da 'Chemical Engineering Design' by Coulson & Richardson, 6th Edition.
The Formula Explained
The VLE calculations use the Raoult's law and Dalton's law for ideal mixtures.
y_i = (x_i * P_i^sat) / P
Glossary of Variables
- Temperature (°C): The operating temperature.
- Pressure (atm): The operating pressure.
- Component 1 Mole Fraction: Initial mole fraction in the liquid phase.
- Component 2 Mole Fraction: Initial mole fraction in the liquid phase.
- Vapor Phase Composition: Calculated composition in vapor phase.
- Liquid Phase Composition: Calculated composition in liquid phase.
Frequently Asked Questions (FAQ)
What is Vapor-Liquid Equilibrium (VLE)?
VLE is the condition when both liquid and vapor phases of a substance are in equilibrium with each other at a given temperature and pressure.
Why is VLE important in chemical engineering?
It is crucial for designing separation processes such as distillation, which relies on differences in vapor pressure to separate components.
What are ideal mixtures?
Ideal mixtures follow Raoult's and Dalton's laws, where interactions between different molecules are similar to those between like molecules.
Can this calculator handle non-ideal mixtures?
This basic calculator is designed for ideal mixtures. Non-ideal mixtures require advanced models like Wilson or NRTL.
What units are used in this calculator?
Temperature is in degrees Celsius, pressure in atmospheres, and mole fractions are unitless.
