diagram of a double-effect falling film evaporator. Condensing vapors from flash tank B1 heat evaporator A2. •1=feed •2=product •3=steam •4=vapors. In chemical engineering, a multiple-effect evaporator is an apparatus for efficiently using the heat from steam to evaporate water. [1]
Concentration values of forced circulation evaporators can handle more than the limits of conventional tubular evaporators when handling feed with dissolved salts and is often used as a finishing evaporator for concentration of liquids to high solid content following low solids multi-stage, TVR or MVR evaporation.

Schematic of a multiple effect desalination plant. The first stage is at the top. Pink areas are vapor, lighter blue areas are liquid feed water. Stronger turquoise is condensate. It is not shown how feed water enters other stages than the first. F - feed water in. S - heating steam in. C - heating steam out. W - Fresh water (condensate) out.
For example, if the feed is a saturated liquid, q = 1 and the slope of the q-line is infinite (drawn as a vertical line). As another example, if the feed is saturated vapor, q = 0 and the slope of the q-line is 0 (a horizontal line). [2] The typical McCabe–Thiele diagram in Figure 1 uses a q-line representing a partially vaporized feed.
The best way to reduce energy consumption is by using multiple-effect evaporators. For multiple-effect evaporators, the steam from outside is condensed by the heating element of the first effect and the vapors produced from the first effect are then recycled back to the second effect, where the feed will be partially concentrated product of the ...
We're one week closer to the end of the 2024 NFL season and cementing the top half of the 2025 NFL draft order.There are nine teams with at least 10 losses entering Week 16 so the order could ...
Multiple effect evaporation (MEE) Thermal vapor recompression (TVR) (also known as thermocompression) A combination of the three methods may be used depending on the process. For instance, a 3-effect evaporator circuit may be installed using MVR to transfer heat.
At least two people have died as severe storms and tornadoes tore through parts of Texas and Mississippi on Saturday, officials said, while a parade of atmospheric river-fueled storms batters the ...
