Vapors from a boiling liquid are removed, concentrating the solution.
Evaporation removes large amounts of water from liquids, while drying removes small amounts from solids.
Temperature, pressure, solubility, and material sensitivity influence evaporation.
The increase in boiling temperature of a solution as it becomes more concentrated.
It maintains heat transfer efficiency by preventing low heat transfer coefficients.
Crystallization may occur if the solute begins to precipitate.
It quantifies the total resistance to heat transfer across multiple phases.
They are suitable for small capacities and low steam costs.
They reuse latent heat from vapor in subsequent effects, reducing steam consumption.
It estimates boiling point rise based on the concentration of solutions.
It condenses vapor without mixing it with cooling water.
It decreases the overall heat transfer coefficient, affecting efficiency.
It enhances heat transfer by pumping liquid through the evaporator.
Higher pressure raises the boiling point of the solution.
Lower feed temperatures require larger heat transfer areas to reach boiling.
The ratio of vapor produced to steam used, indicating efficiency.
It typically decreases, necessitating agitation to maintain efficiency.
The removal of solvent, usually water, from a liquid solution.
Open kettle, horizontal tube, vertical long tube, falling film, and forced circulation evaporators.
It can lead to entrainment losses and affect heat transfer.
