Study Notes
Separation Processes
Filtration
- A mechanical separation process used to separate solid particles from a fluid (liquid or gas)
- Based on size exclusion, where particles larger than the filter pores are retained
- Types of filtration:
- Gravity filtration
- Vacuum filtration
- Pressure filtration
- Applications:
- Solid-liquid separation
- Wastewater treatment
- Laboratory-scale separations
Distillation
- A thermal separation process used to separate components based on boiling points
- Based on the difference in vapor pressures of the components
- Types of distillation:
- Simple distillation
- Fractional distillation
- Vacuum distillation
- Applications:
- Petroleum refining
- Chemical processing
- Pharmaceutical production
Phase Equilibria
- The study of the equilibrium between different phases (solid, liquid, gas)
- Described by phase diagrams, which show the relationship between temperature, pressure, and composition
- Types of phase equilibria:
- Vapor-liquid equilibrium (VLE)
- Liquid-liquid equilibrium (LLE)
- Solid-liquid equilibrium (SLE)
- Importance in separation processes:
- Understanding phase equilibria is crucial for designing and optimizing separation processes
Volume Liquid Equilibrium (VLE)
- A type of phase equilibria that describes the equilibrium between a liquid and a vapor phase
- Described by the equilibrium curve, which shows the relationship between temperature, pressure, and composition
- Importance in distillation:
- Understanding VLE is crucial for designing and optimizing distillation columns
Flash Distillation
- A type of distillation where a mixture is partially vaporized and then separated
- Used for:
- Separating components with similar boiling points
- Deodorizing and dehydrating fluids
- Advantages:
- Fast and efficient
- Low energy consumption
Steam Distillation
- A type of distillation that uses steam to separate components
- Used for:
- Separating heat-sensitive compounds
- Extracting essential oils from plants
- Advantages:
- Gentle on the components
- Energy-efficient
LLE (Liquid-Liquid Extraction)
- A separation process used to separate components based on their solubility in different liquids
- Used for:
- Separating components with similar boiling points
- Purifying pharmaceuticals and chemicals
- Types of LLE:
- Single-stage extraction
- Multi-stage extraction
- Continuous extraction
