Abstract
A process for the removal of solid particles from a mixture containing at least one liquid chlorinated hydrocarbon is described. The solids-containing liquid mixture is introduced into at least one hydrocyclone having a downstream separator. The liquid mixture which has been enriched in solids and discharged from the hydrocyclone is preferably subjected to sedimentation of the solid particles, without the use of centrifugal forces. Efficient removal of interfering particles is achieved in this way, together, with long service lives and a minimum of emission.
