To separate substances (that have different boiling points).
Distillation is based on the boiling points of the different components of a solution.
flooding in disillation column is control: 1) to reduce total crude charge, 2)to decrease the transfer temperture, 3) increase the tower reflux, 4) increase the tower pressure.
Distillation is a method of separating components of a liquid mixture based on differences in boiling points. The mixture is heated to vaporize the more volatile component, which is then condensed back into a liquid form and collected separately from the less volatile components. It is commonly used in industries such as petrochemicals, food and beverage, and pharmaceuticals for purification and separation purposes.
To separate a liquid mixture through distillation, you would need a distillation apparatus, which typically includes a distillation flask, a heat source, a condenser, and a receiving flask. The heat source vaporizes the liquid mixture, while the condenser cools the vapor back into liquid form, allowing for the collection of separated components based on their boiling points. If the mixture consists of multiple liquids with close boiling points, fractional distillation equipment may be required for better separation.
In the beginning of the short story "Distillation," the narrator describes a visit to a small village marked by a strong smell of alcohol. The narrator meets an old man named Sona who is known for his craft of making moonshine. The story sets up the scene for an interaction between the narrator and Sona, exploring themes of tradition, rural life, and craftsmanship.
