Abstract

A procedure for the separation of water from a mixture composed substantially of gasification coal and water, characterized in that the mixture is dynamically squeezed with the help of a band filter press and, per cycle, the filter bands, between which the mixture of carbon and water, change direction several times forming an angle of at least 90º, at least one of the bands being permeable to water.
