Abstract |
Solvent extraction is a treatment technology that uses a solvent (a fluid that can dissolve another substance) to separate or remove hazardous organic contaminants from sludges, sediments, or soil. Solvent extraction does not destroy contaminants. It concentrates them so they can be recycled or destroyed. It is used in combination with other technologies to destroy the separated concentrated contaminants. When the soil enters an extractor (a tank where the contaminated soil is mixed with the solvent), the soil is separated into three components, or fractions: solvent with dissolved contaminants, solids, and water. Contaminants are concentrated into each of these fractions. For example, PCBs (polychlorinated biphenyls) concentrate in the contaminated solvent mixture, while metals are left behind in the solids and water. |
