Is superdistillation the same as precision distillation?
Thread Content
As the title suggests: “superfractionation” refers to superdistillation. So is superdistillation the same as precise distillation? Is there any difference?
The question might be a bit silly, but those who know the answer could please reply, even with just one or two words – yes or no is fine. Thank you
Precision distillation: refers to the method of using distillation to separate mixtures with similar boiling points. In a precision distillation system, the relative volatility is close to 1, which results in a relatively high operating reflux ratio. Ultra-distillation: This approach is used when the relative volatility between the two components to be separated is low, and high quality requirements are imposed on the product. Ultra-distillation is characterized by a large number of trays, high reflux, and stringent requirements for operational control. As can be seen from the definition, ultra-distillation and precision distillation have many similarities, but they are not the same thing; ultra-distillation seems to require higher standards for product quality. Searching on the web also yields the term ultra-precise distillation. This post was last edited by zhangyong6404 on 2009-3-20 18:09.]
