Distillation Columns
Distillation columns are used in small scale laboratories as well as in big manufacturing types of industries such as General Chemical Production,Petrochemicals and Renewable Fuels. Distillation is a separation technique that utilizes differences in boiling points between two or more chemical substances in their liquid phase.
For example, water boils at 100°C at atmospheric pressure, or 1 Bar. At 0.1 Bar, it boils at 50°C. In this example, water has a vapor pressure of 1Bar at 100°C and 0.1 Bar at 50°C. Ethanol, as another example, has a vapor pressure of 2.2Bar at 100°C and 0.31 Bar at 50°C.
Since the vapor pressure of ethanol is higher than water, it is more volatile. There are two main column options for a distillation system: trayed columns and packed columns, which differ in their shape, reliability, and ability to withstand pressure.
