Five-Column Three-Effect Distillation Process
Our company designs and manufactures latest Five-Column Three-Effect Distillation equipment. This new process is promoted on the basis of traditional five-column differential-pressure column and mainly used for super-fine alcohol production.
The key of this process is the heating methods, the steam heats one column directly and transfers the heat to other 4 columns to achieve three-effect thermal coupling and energy-saving effects.
In terms of electricity efficiency, it can save 50% electricity and avoid the repairing of circulating pumps and also extend the working life of there-boilers.
Double-Mash-Column Three-Effect Distillation Process
This process applies to the production of general-grade alcohol& fuel ethanol, and it was awarded Chinese national patent, it is the only successful application of double mash column & three-effect in the world, which produces general-grade alcohol.
This process is composed by mash column, rectification column and composite column. The composite column functions as mash column and rectification column.
The key of this process is 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
