Multi-stage flash distillation
http://dbpedia.org/resource/Multi-stage_flash_distillation an entity of type: Election
Multi-stage flash distillation (MSF) is a water desalination process that distills sea water by flashing a portion of the water into steam in multiple stages of what are essentially countercurrent heat exchangers. Current MSF facilities may have as many as 30 stages. Multi-stage flash distillation plants produce about 26% of all desalinated water in the world, but almost all of new desalination plants currently use reverse osmosis due to much lower energy consumption.

多级闪蒸，是一种海水淡化方法。强调多级和闪蒸，其装置由多个闪蒸室组成的. 该装置中利用了海水的蒸发进行脱盐，先将海水加热，再引入接近真空的闪蒸室，由于室内的气压远远低于热海水的饱和蒸汽压，壓力低連常溫的水實際上也會沸騰，所以海水瞬间气化，将室内气化的蒸汽冷却，成为淡水并将其引出，而剩余的热海水再进入下一个闪蒸室，继续接受闪蒸，多次提取热海水中的淡水。 原理：即液体在沸点时将产生蒸汽的原理，将溶液中的水份转变成蒸汽，而与溶解于溶液中的盐份分离。闪化（ Flashing ）以减压方式降低沸点，并产生蒸汽，再将蒸汽冷凝后即可制得淡水。由于此方法并没有使含盐水真正沸腾（仅是表面沸腾）与热传表面积接触，可以大幅改善因蒸馏产生的积垢（ Scale ）问题，并于 1950 年代即已有商业化规模，加上其产量较大，广为中东产油国所采用。
