Study Notes
Classification of Separations
- Separations are classified according to the type of property used to achieve separation, such as differences in density, solubility, or particle size.
Purpose of Separation Processes
- Separation processes aim to separate mixtures into their individual components or to remove impurities from a product.
Need for Separation Processes
- Raw materials often require separation processes because they are usually found in mixtures in nature.
- Separation processes are necessary to obtain a desired product or to remove impurities.
Challenges in Separation
- If no single difference can be used to accomplish the desired separation, multiple stages or combination of processes are often needed.
Outcome of Separation
- At least one product mixture from the separation process is enriched in the desired component.
Properties Exploited in Separation
- Separation processes often exploit differences in physical or chemical properties, such as density, solubility, or particle size.
Purpose of Separation
- The purpose of a separation process is to separate mixtures into their individual components or to remove impurities from a product.
Natural State of Elements or Compounds
- Elements or compounds are often found in nature in mixtures or as impure substances.
Outcome of Some Separations
- The outcome of some separations is a purified or isolated product.
Classification of Separation Methods
- Separation methods are often classified as mechanical separations, solvent-based separations, or thermal separations.
