Question

disadvantage of atmospheric distillation​

Answer 1

Explanation:

Disadvantages. Most cost efficient distillation column for diameters greater than 0.6 m. The liquid/vapor contact in the cross-flow of plate columns is more effective than the countercurrent-flow in packed columns.

requires the liquids to have large boiling point differences (>70oC) gives poorer separation than fractional distillation only works well with relatively pure liquids

Answer 2

Answer:

The disadvantages of distillation are the energy needs of the unit, the cost, and the slow output. There is also the concern that since distilling water removes all minerals, drinking distilled water may "leach out" minerals such as calcium, magnesium, and fluoride from the body.
