Energy Efficient SS304 Cooling Tower and Absorption Column for New Technology

Product Description

Distillation is one of the most common and energy-intensive separation processes. The effectiveness of separation is dependent upon the height and diameter of the column, the ratio of the column's height to diameter, and the material that comprises the distillation column itself. In a typical chemical plant, it accounts for about 40% of the total energy consumption. Industrial distillation is typically performed in large, vertical cylindrical columns known as "distillation towers" or "distillation columns" with diameters ranging from about 65 centimeters to 6 meters and heights ranging from about 6 meters to 60 meters or more.
 

 

Industrial distillation towers are usually operated at a continuous steady state. Unless disturbed by changes in feed, heat, ambient temperature, or condensing, the amount of feed being added normally equals the amount of product being removed.

 

The amount of heat entering the column from the reboiler and with the feed must equal the amount of heat removed by the overhead condenser and with the products. The heat entering a distillation column is a crucial operating parameter, the addition of excess or insufficient heat to the column can lead to foaming, weeping, entrainment, or flooding.

Double-Mash-Column Three-Effect Distillation Process
 
The key of this process lies in the heating methods: The steam heats one column directly and transfers the heat to other 2 columns to achieve three-effect thermal coupling and energy-saving effects. The advantage of this process is energy-saving; it saves over 40% steam. 

 

Fractionating columns are widely used in the chemical process industries where large quantities of liquids have to be distilled. Such industries are petroleum processing, petrochemical production, natural gas processing, coal tar processing, brewing, liquified air separation, and hydrocarbon solvents production and similar industries but it finds its widest application in petroleum refineries.

 

The application of distillation can roughly be divided into four groups: laboratory scale, industrial distillation, a distillation of herbs for perfumery and medicinals (herbal distillate), and food processing. The latter two are distinctively different from the former two in that distillation is not used as a true purification method but more to transfer all volatiles from the source materials to the distillate in the processing of beverages and herbs.

 

In continuous distillation, the source materials, vapors, and distillate are kept at a constant composition by carefully replenishing the source material and removing fractions from both vapor and liquid in the system. This results in a more detailed control of the separation process.
