The reaction vessel within the meaning of methodology for chemical process to purify

摘要

The present invention relates to a method for cleaning a container (30) and conduits (32, 33, 36) associated with said container by adding a cleaning solvent to the container and circulating said solvent through said conduits back to said container. In accordance with the invention 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 said conduits to said container, said container and conduits thus intermittently being flushed with clean solvent.
