Title
(EN) PROCESS FOR EXTRACTING FIXED AND MINERAL OILS
(FR) PROCEDE D'EXTRACTION D'HUILES FIXES ET MINERALES
Abstract
(EN)
The present invention relates to a method of extracting and concentrating oils from materials in which the oils are already dispersed. More particularly, the present invention is concerned with the extraction of fixed oils or mineral oils from materials using a process of solvent extraction which is performed under elevated pressure and temperature. The solvent medium may be HFC 134a alone, or HFC 134a in combination with a suitable co-solvent which can be determined in accordance with the invention.
(FR)
La présente invention concerne un procédé d'extraction et de concentration d'huiles à partir de matières dans lesquelles les huiles sont dispersées. Plus particulièrement, l'invention concerne l'extraction d'huiles fixes ou d'huiles minérales contenues dans des matières à l'aide d'un procédé d'extraction par solvant mis en oeuvre dans des conditions de pression et de température élevées. Le milieu solvant peut être du HFC 134a seul, ou du HFC 134a combiné à un cosolvant approprié pouvant être déterminé selon l'invention.
