冷回流(过冷液体回流)--塔顶气相馏出物在冷凝器中被全部冷凝后,再将其冷却到其泡点温度以下,就成为过冷液体,用这种过冷液体作为回流,称为冷回液. 循环回流是从塔内抽出的热液体经冷却后再泵送回塔的液体。

循环回流是常规调整手段,冷回流是在循环回流将温度将不下来时使用,效果很明显

冷回流--塔内馏介质在冷凝器中被全部冷凝后,再将其作为回流,称为冷回液. 循环回流是从塔内抽出的热液体经泵送回塔内。

意思是不是循环回流的冷却程度没有冷回流大啊

楼主应该弄明白区别了吧 最重要的区别就是组分不一样

冷回流一般是塔顶气相经冷却器到40度以下的过冷液回流,循环回流一般是塔某一层塔板抽出一部分液相经换热冷却后打入抽出板上几层板位置。

冷回流有相变,循环回流没有相变,所以相同质量的冷回流要比循环回流的作用大
