精馏塔培训材料翻译？ 我单位关于内、外回流(internal, external reflux)的定义 reflux to a column is defined as the quantity of vapour condensed at the top of the column that is returned to the column. this is commonly indicated by the amount of flow measured via a flowmeter from the reflux drum to the column, or the external reflux. internal reflux is defined as the external reflux returned to the column plus additional reflux that results from condensing some of the overhead vapour with subcooled external reflux. subcooling occurs when the temperature of the liquid is less than the boiling temperature at a given pressure. 这两个回流其实都相当于楼上观月所说的外回流，只不过细分了一下。哪位有兴趣可以翻译一下。查看更多
