Abstract :
Supercritical fluid extraction (SCFE) is a soil remediation technology. At present, only
a few companies are using from this method, all of which are technical based on conventional
methods of extraction such as soilex solvent extraction. Because of the hard enforcement of
environmental conservation law, using green technology seems imperative. This paper endeavors
to carry out the feasibility studies of supercritical fluid extraction units for such as purpose. It also
analyzes the cost and benefit of these processes in industrial scale and presents an economical
approach for this purpose. If compared to other remediation processes, the supercritical CO2 extraction
(whit CO2recycling) shows relevant economical advantages.
