Write the difference between natural evaporation and forced circulation evaporation
Answers
Answer:
Explanation:
Circulation evaporators are a type of evaporating unit designed to separate mixtures unable to be evaporated by a conventional evaporating unit. Circulation evaporation incorporates the use of both heat exchangers and flash separation units in conjunction with circulation of the solvent in order to remove liquid mixtures without conventional boiling. There are two types of Circulation Evaporation; Natural Circulation Evaporators and Forced Circulation Evaporators, both of which are still currently used in industry today, although forced Circulation systems, which have a circulation pump as opposed to natural systems with no driving force, have a much wider range of appropriate uses.
The change of liquid into its vapour form at any temperature point is called as evaporation. Evaporation is a surface phenomena.
» The conditions that increases the rate of evaporation are :-
→ Increase in Temperature :- The increase in temperature makes evaporation faster.
→ Increase in Surface area :- Increasing the surface area also makes evaporation faster.
→ Increase in wind speed :- Increasing the wind speed increases evaporation rate.
→ Decreasing humidity :- Decreasing humidity increases the rate of evaporation for water.
