Heat transfer to a boiling liquid occurs so frequently that it is considered an individual operation. It is called evaporation. The objective of evaporation is to concentrate a solution consisting of a nonvolatile solute and a volatile solvent. In the overwhelming majority of cases, the solvent is water. Evaporation takes place by vaporizing a portion of the solvent in order to produce a concentrated solution or a thick liquid. Evaporation differs from drying in that the residue is a liquid – sometimes one with high viscosity – rather than a solid; it differs from distillation in that the vapor is usually a single component, and even when the vapor is a mixture, no attempt is made to separate it into various fractions during the evaporation process; it also differs from crystallization in that the focus is on concentrating the solution rather than forming crystals. In some situations, such as when evaporating brine to produce table salt, the distinction between evaporation and crystallization is not clear-cut. Evaporation can sometimes result in a slurry of crystals within a saturated mother liquor
I used DuNiang Translation to carry out the translation and encountered several issues; in some cases, words were misidentified as something else due to the lack of spaces between them. Is “Evaporationis” a typo for “Evaporations”? The translation provided by DuNiang Translation is as follows, and it still needs to be improved by the original poster: When a liquid reaches a boiling point, it is often considered to be the result of human action. It is called evaporation. The purpose of evaporation is to deal with solutions that contain non-volatile solutes and a solvent. The majority of the solvent that evaporates is water. Evaporation volume refers to the concentrate or strong liquor produced by the evaporation of part of the solvent. The residue resulting from evaporation is different from that of drying: it is a liquid – sometimes highly viscous – rather than a solid. It also differs from distilled steam, which is usually a single component; even in the case of mixed steam, no attempt is made to separate the steam into various fractions during the evaporation process ； It differs from focusing on the concentration of the solution stored, rather than the formation and growth of crystals. In some cases, for example, in the production of table salt through saltwater evaporation, the boundary between evaporation and crystallization is not sharp. Evaporation sometimes produces a crystalline slurry in the saturated mother liquor
