Mass Transfer in Chemical Engineering Quiz

Distillation Equipment

• Commonly used equipment includes distillation columns, condensers, and reboilers.
• Distillation columns can be packed or tray columns, selected based on the separation efficiency required.
• Other equipment may include heat exchangers and receivers for collecting distillate.

Purpose of a Desiccant

• Desiccants are materials specifically designed to remove moisture from the air or other gases.
• They are crucial in drying processes to ensure product stability, quality, and shelf-life by preventing moisture-related degradation.
• Common desiccants include silica gel, calcium sulfate, and molecular sieves.

Absorption in Mass Transfer

• Absorption refers to the process where a gas permeates a liquid or solid phase, resulting in the gas being taken up and dissolved.
• This process is essential in various applications such as air purification, carbon capture, and chemical production.
• Key parameters include the mass transfer coefficient and the equilibrium relationship between phases.

Solvent Extraction Process

• Solvent extraction is commonly used in liquid-liquid extraction processes.
• It separates compounds based on their solubility differences in two immiscible liquids, typically water and an organic solvent.
• Widely applied in pharmaceuticals, food industries, and metal recovery from ores.
