Evaporative Vs. Cooling Crystallization Systems - Thermal .

Vacuum evaporation is the process of causing the pressure in a liquid-filled container to be reduced below the vapor pressure of the liquid, causing the liquid to evaporate at a lower temperature than normal. Although the process can be applied to any type of liquid at any vapor pressure, it is generally used to describe the boiling of water by lowering the container's internal pressure below .

Evaporation - Lenntech

The capacity of a multiple effect evaporator (n effects) is ca. n*single effect evaporator capacity and the economy is about 0.8*n. Evaporators need also pumps, interconnecting pipes and valves that are required for transfer of liquid from one effect to another effect and they increase both the CAPEX and OPEX of the process.
