Abstract

En fremgangsmåte for rengjøring av rør i drift ved en prosess omfatter at man i rørene innfører partikler som føres med av fluidet som sirkulerer 1 rørene hvorefter man fjerner partiklene fra fluidet.Fremgangsmåten finner spesiell anvendelse for av-koksing av pyrrolyseovner for dikloretan.
