摘要： Polyester granules are crystallized and dried by passing hot gasses of 120.degree. to 190.degree. C in upward direction through the stationary layer of loose polyester granules resting in a cylindrical container on a plane or conical perforated tray slowly rotating about its vertical axis. The hot gas is passed through the material in an amount such that no fluidization is brought about. Under the action of the hot gas the granules agglomerate and the agglomerate is alternately slightly lifted and lowered again by stripping edges on the perforated tray whereby the agglomerate portion resting on the tray is disintegrated and the crystallized granules are discharged through slots behind the stripping edges in the tray.

摘要： 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.
