ABSTRACT:
A process for replacing a solution obtained for instance by exposing oil shale particles to the action of a solvent under supercritical conditions, by a solvent is provided for. The solid/solution mixture is extracted in a multitude of cross flow extractions such as to gradually replace the solution e.g. a bitumen solution, by the solvent, e.g. toluene. An apparatus for carrying out this process is also disclosed.
