Ethanol production ethylene alcohol
2. The distillation (Distillation)
.Distillation process. Applying heat to boiling point substances under evaporation off and condensation (through the condenser with cooling), a liquid. Out of the ingredients in alcohol distillation flesh to use.Within the distillation sequence is called tray layers with different characteristics and are used tray type ใดขึ้นอยู่กับ Design
.Fermentation alcohol 9 - 10% will be entered into the middle reboiler and flow down the various classes until the lower end of the column, as the heat source. (mostly using steam style direct steam)
.Within the distillation column, there is an exchange of heat between liquid condensate falling below the evening birds that with a vapor liquid heat over which rises above.Vapor liquid floated when heated to steam the other. I cool down, some of which have a high boiling point To condense liquid falls. Hanging is the forever!We see that the AI will contain substances with low boiling point (in this flesh mostly alcohol), which will be divided up to the top column. This once through the condenser. To condense liquid called forth Distillate.Ethylene ethyl alcohol is, and if in Distillate didn't flesh alcohol. 9 5% will bring back into the Reflux in new หอกลั่น until 9. 5%. The liquid which condenses in column will contain the substance with high boiling point (in this case is water).Which will fall as Residue or Bottom product at the bottom of the distillation column.
