Process for the treatment of cork or a cork-based material particularly with a view towards extracting contaminating organic compounds, in which said cork or said cork-based material is put into contact with a dense fluid under pressure at a temperature of from 10 to 120&#xb0; C. and at a pressure of from 10 to 600 bars. Manufacturing installation for parts made of cork or a cork-based material, such as bottle corks, comprising an installation for treatment or extraction by putting the said cork or the said material into contact with a dense fluid under pressure.

Process for treatment and extraction of organic cork compounds by a dense fluid under pressure

Method for treating and extracting cork organic compounds, with a dense fluid under pressure

The invention relates to a method of tangential filtration of a viscous fluid or liquid in which a supercritical substance is dissolved in a supercritical state in this viscous fluid or liquid so as to lower the viscosity. The invention also relates to the installation for the implementation of the method. The invention is applicable particularly to the filtration of heat sensitive organic liquids and used motor oils.
