What is Evaporation ?

Evaporation is the removal of solvent as steam from a solution or slurry. For the vast majority of systems of evaporation of the solvent is water. The goal is usually to focus a solution; Consequently, the vapor is not the desired product and can or cannot be retrieved depending on its value. Therefore, evaporation is usually obtained by spraying a portion to produce a concentrated solution, liqueur often or slurry of solvents.

Evaporation often invades denominated transactions distillation, drying and crystallization. In evaporation, no attempt to separate the components of steam. This distinguishes evaporation distillation. Evaporation is distinguished by drying as the residue is always a liquid. The desired product can be a solid, but the heat must be transferred into the evaporator a solution or solid suspension in a liquid. The liquid can be highly viscous or a leachate. Evaporation differs from crystallization in evaporation takes care to concentrate a solution rather than producing or building crystals.

    Having read this I believed it was extremely
    enlightening. I appreciate you taking the time and energy to put this content together.
    I once again find myself spending a lot of
    time both reading and posting comments. But so what, it was still worth
    it!
