Abstract
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.
