fractional distillation 【化學】分餾(作用)。

Researches into the nuclear fusion reactions has created a need for handling the deuterium tritium fuel employed , and cryogenic fractional distillation was selected as one of the best process for making the required separations due to relatively large separation factors , low power consumption , high throughputs , relatively short start - up times , and flexibility of design 受控聚變的研究已給人類展示出取得更加安全、清潔,而且是無限豐富的能源的美好前景。在廉價制取聚變燃料氘以及提高核能原料利用率的方法中,低溫精餾被認為是最經濟可行的分離氫同位素的方法。

The main method of separation used in refineries is fractional distillation , although further processing is normally required to produce marketable petroleum products 分離石油主要采用的方法就是分餾,然后通過深加工才能得到可以銷售的石油產品。
