Ethanol Distillation Tower

Column tray of the distillation tower
A tray tower is a widely used gas-liquid mass transfer equipment, consisting of a cylindrical shell and a number of trays horizontally arranged at certain intervals within it. In normal operation, the liquid flows downward through each tray layer under the force of gravity and is discharged from the bottom of the tower; the gas, propelled by a pressure difference, passes through the trays from bottom to top through openings evenly distributed on the trays and is discharged from the top of the tower. Some liquid is retained on each tray, and during the passage of the gas through the liquid layer on the tray, the two phases come into contact and undergo mass transfer.

A distillation column is a tower-type vapor-liquid contacting device used for distillation, also known as a distillation tower. It comes in two main types: plate towers and packed towers. Based on the operating method, it can be further divided into continuous distillation columns and batch distillation columns. Operation pressure-wise, it includes atmospheric, pressurized, and vacuum conditions. The basic principle of distillation involves multiple partial vaporization and condensation of the liquid, utilizing the different volatility of its components (relative volatility, α) to achieve separation. Distillation can be categorized by its operation methods into simple distillation, flash distillation, normal distillation, and special distillation, among others.
