多效蒸发将几个蒸发器串联运行的蒸发操作，使蒸汽热能得到多次利用，从而提高热能的利用率，多用于水溶液的处理。在三效蒸发操作的流程（见图）中，第一个蒸发器（称为第一效）以生蒸汽作为加热蒸汽，其余两个(称为第二效、第三效)均以其前一效的二次蒸汽作为加热蒸汽，从而可大幅度减少生蒸汽的用量。每一效的二次蒸汽温度总是低于其加热蒸汽，故多效蒸发时各效的操作压力及溶液沸腾温度沿蒸汽流动方向依次降低。依据二次蒸汽和溶液的流向，多效蒸发的流程可分为：①并流流程。溶液和二次蒸汽同向依次通过各效。由于前效压力高于后效，料液可借压差流动。但末效溶液浓度高而温度低,溶液粘度大,因此传热系数低。②逆流流程。溶液与二次蒸汽流动方向相反。需用泵将溶液送至压力较高的前一效，各效溶液的浓度和温度对粘度的影响大致抵消，各效传热条件基本相同。③错流流程。二次蒸汽依次通过各效，但料液则每效单独进出，这种流程适用于有晶体析出的料液。在生蒸汽温度与末效冷凝器温度相同（即总温度差相同）条件下，将单效蒸发改为多效蒸发时，蒸发器效数增加,生蒸汽用量减少，但总蒸发量不仅不增加,反而因温度差损失增加而有所下降。多效蒸发节省能耗，但降低设备的生产强度，因而增加设备投资。在实际生产中，应综合考虑能耗和设备投资，选定最佳的效数。烧碱等电解质溶液的蒸发，因其温度差损失大，通常只采用2～3效（见彩图）；食糖等非电解质溶液,温度差损失小,可用到4～6效；海水淡化所蒸发的水量大，在采取了各种减少温度差损失的措施后，可采用20～30效。
