The Evaporation Process
How Does the Evaporation Process Work?
veryone knows that when you apply heat to water the water evaporates. The same is true of many other liquid solvents. When that water or solvent is part of a solution with other substances, those other substances are left behind as residue when the water evaporates. If you evaporate some portion of the water, but not all of it, you are left with a concentrated solution and—if you recondense the evaporated water—clean water. The evaporation process leverages these basic scientific principles to both concentrate liquids (in the forms of solutions, suspensions and emulsions) to make them more useful and to “free the water” or other pure solvents from other substances in solution. The evaporation process is used for a huge variety of tasks, from concentrating juices and dairy products, to reducing industrial wastewater, and much more. In fact, the uses of evaporation are almost limitless.
he challenge for evaporation process engineers, like Caloris, is to create systems that apply evaporation in ways that maintain the quality of the liquid during evaporation while avoiding heat damage to the concentrate, and doing it efficiently.
