What is the main difference between distillation and distillation

The main difference between distillation and evaporation is the process of operation and the effect of separation.

Distillation is a process in which a liquid mixture is heated to evaporate its low-boiling-point components, and then the individual components are condensed and collected. It is primarily used to separate liquid mixtures, and is a relatively simple, universally applied separation technique. Distillation operations are usually carried out at atmospheric pressure or under pressure, and can handle various types of liquid mixtures with relatively low equipment requirements.

Fine distillation is a more elaborate separation process, in which a liquid mixture is separated with high purity through multiple distillations and condensation processes. Distillation operations are typically performed at higher pressures and temperatures and require the use of complex equipment, including multiple towers, reboilers, and condensers. Compared to distillation, distillation provides a better separation and results in a higher purity product.

In summary, both distillation and vaporization are commonly used processes for separating liquid mixtures, and the specific choice of process depends on material characteristics and separation requirements. Distillation is suitable for simple separation of liquid mixtures, while distillation is suitable for occasions where high purity separation is required.
