【Daily Question 2019】Hydrogen production and hydrogenation section – Question No. 008: What is the difference between distillation and rectification? Both distillation and rectification rely on vaporization and condensation to achieve separation. Distillation uses partial vaporization or partial condensation to separate the mixture to achieve a certain degree of purity ； Distillation, on the other hand, uses multiple vaporizations and condensations to achieve a higher degree of purity in the separation of mixtures. (Unless otherwise specified, all questions and answers are based on hydrogenation units.) ) Correct: 3 wealth, Incorrect: 1 wealth ； Mass posting of posts – rated based on the lowest score ； Replies that are unrelated to the answer are considered spam and will be deleted immediately.

Distillation is a distillation method that uses reflux to achieve high-purity separation of liquid mixtures； Distillation is a thermodynamic separation process that utilizes the difference in boiling points of various components within a mixed liquid or liquid-solid system; it involves the evaporation of components with lower boiling points, followed by condensation, thereby enabling the separation of all components. It is a combination of the two unit operations of evaporation and condensation.
Distillation involves liquid reflux, while simple distillation does not； Distillation uses tower equipment, while simple distillation employs a distillation kettle ； Distillation involves multiple stages of partial vaporization and multiple stages of partial condensation, while simple distillation generally involves only one such stage ； The purity of the distillate and residue from distillation is very high, whereas it is lower in simple distillation
