Solvent extraction is a process in which compounds are separated based on their relative solubilities. 

This treatment method involves using a solvent – a fluid that has the ability to dissolve another substance. 

Solvent extraction is used across multiple industries, including during the processing of perfumes and vegetable oil. It’s also commonly used in petrochemical refining industries.

Solvent extraction is used to separate hazardous contaminants from sludge and sediments as well. This can be especially beneficial for hazardous waste generators since solvent extraction ultimately reduces the amount of hazardous waste that must be treated. 

Solvent extraction does not destroy a compound. It instead separates it, a process that can provide several valuable benefits depending on the industry in which the process is used.
