How Does Extraction Compare To Distillation?

No Comments

One of the main differences between solvent extraction and solvent distillation is that solvent extraction can purify either a substance that is a liquid or one that is in a solid phase. Solvent distillation purifies a substance that is only in a liquid mixture.

There are various types of distillation techniques, from steam distillation to vacuum distillation. The difference among these is the technique used to separate compounds. 

At Temarry Recycling, solvent distillation recovery is based on how the vapor of a boiling mixture will be richer in low boil point components. These include acetones, ketones, aliphatic hydrocarbons and alcohols. 

When vapor is cooled and condensed, the liquid condensate becomes a valuable product that can be sold back into industry. The higher boiling point portion of the original mixture that does not vaporize remains in the bottom of the recovery still used on site for the distillation process. One benefit of using this type of distillation process is that the portion remaining in the recovery still is valuable as an alternative fuel source for facilities such as cement kilns.

Solvent recycling offers a more environmentally-friendly way to dispose of hazardous substances, and distillation is the most common method of solvent recycling.
