Ethanol Distillation Tower

Product description:

1. Ethanol distillation tower is a common chemical equipment used to separate ethanol from other impurities and achieve purification. It is an important separation technology widely used in the chemical industry.

2. The working principle of an ethanol distillation tower is based on the differences in boiling points of different components. Ethanol has a different boiling point from other impurities, and separation can be achieved by heating it in the tower, evaporating it, and then condensing and recovering it at the top of the tower. Specifically, an ethanol distillation tower typically consists of a tower body, a tray, a condenser, and a reflux device.

3. The tower body is the main structure of an ethanol distillation tower, usually in a vertical cylindrical shape, with a tray installed inside. The tray is similar to a partition, used to increase the contact area inside the tower and promote mass transfer between ethanol and other components. There are also holes on the tray that allow gas and liquid to exchange inside the tower.

4. The condenser is a part of the tower body used to condense steam into liquid. A condenser is usually composed of a shell and tube heat exchanger, which condenses steam internally through a cooling medium. The condensed liquid can be returned to the tower body through the reflux device at the bottom of the tower body, improving the separation effect.

5. The reflux device is one of the key equipment in the ethanol distillation tower, used to control the liquid reflux rate inside the tower. The reflux device regulates the liquid concentration inside the tower by controlling the liquid reflux rate, thereby affecting the separation effect. The reflux device usually consists of a liquid level control system, a condenser, and a pump.

6. In the ethanol distillation tower, the separation of ethanol from other components is achieved through multi-stage distillation. Ethanol undergoes processes such as vapor liquid equilibrium, vapor liquid mixing, and vapor liquid separation in the tower, ultimately achieving purification.
