Mass transfer is the net movement of mass from one location (usually meaning stream, phase, fraction or component) to another

The movement of heat across the border of the system due to a difference in temperature between the system and its surroundings

Distillation is a process used to separate mixtures by heating and cooling. Types include simple, fractional, and vacuum distillation.

• Simple distillation is used to separate liquids with different boiling points.

• Fractional distillation is used to separate liquids with similar boiling points.

• Vacuum distillation is used to separate liquids with high boiling points or heat-sensitive compounds.

Adsorption is the process of attracting and holding molecules or particles on a surface.

• Physical adsorption: weak van der Waals forces between adsorbate and adsorbent

• Chemical adsorption: chemical bonds form between adsorbate and adsorbent

• Examples: activated carbon adsorbing impurities from water, silica gel adsorbing moisture from air

Distillation is a process of separating components of a mixture based on their boiling points.

• There are two main types of distillation: batch distillation and continuous distillation.

• Batch distillation involves separating a mixture into its components in a single batch, while continuous distillation involves separating a mixture into its components over a continuous process.

• Other types of distillation include vacuum di...read more

Adsorption is the process of binding molecules or particles to a surface.

• Physical adsorption: weak van der Waals forces between adsorbate and adsorbent

• Chemical adsorption: strong covalent bonds between adsorbate and adsorbent

• Examples: activated carbon for physical adsorption, zeolites for chemical adsorption

• Adsorption is used in various industries such as water treatment, gas purification, and pharmaceuticals
