The plate falling film evaporator has advantages of high capacity, less steam consumption and high return water ratio but is not suitable for evaporation of solution with crystal liberation.

板式降膜蒸发器具有蒸水能力大、汽耗低、回水比高等优点，但不宜蒸发有结晶析出的溶液。 山西铝厂拜尔法母液中碳碱含量高，在蒸发过程中易析出。

The evaporation capacity calculated by Penman-Monteith formula is suggested to replace the water surface evaporation observed for an improved regression.

建议使用彭曼公式计算的蒸发能力代替实测水面蒸发以提高拟合效果。
