PROBLEM TO BE SOLVED: To provide a method for cleaning a container (30) and conduits (32, 33, 36) associated with the container by adding a cleaning solvent to the container and circulating the solvent through the conduits back to the container. SOLUTION: The cleaning solvent additionally is forced intermittently through a filter unit (1) containing an absorbent material, preferably active carbon (3), and then is allowed to flow through the conduits to the container, the container and conduits thus intermittently being flushed with cleaning solvent. The container may be a reaction vessel for chemical processes. COPYRIGHT: (C)2008,JPO&INPIT
