2020-5-31ABSTRACT 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.

Supercritical fluid extraction. The advantages of supercritical fluid extraction compared with liquid extraction are that it is relatively rapid because of the low viscosities and high diffusivities associated with supercritical fluids. The extraction can be selective to some extent by controlling the density of the medium, and the extracted.

Microalgae are one of the most promising feedstocks for biodiesel production due to their high lipid content and easy farming. However, the extraction of lipids from microalgae is energy intensive and costly and involves the use of toxic organic solvents. Compared with organic solvent extraction, supercritical CO 2 SCCO 2 has demonstrated advantages through lower toxicity and no solvent.

2015-7-28New methods are therefore being investigated in order to improve the remediation efficiency, lower the costs or the remediation time. Soil remediation by supercritical fluid extraction is one of those methods. There is general agreement in recognising the supercritical fluid extraction as a rather efficient, fast and low expensive treatment for.

As an alternative to current methods, supercritical fluid extraction SFE has been evaluated for in-the-field coal and petroleum gasification waste site characterization. The gas-like mass transfer properties of supercritical fluids allow more rapid extraction rates and more efficient penetration of the matrix than conventional solvent.
