ABSTRACT:
The in-situ cleaning of conduits containing oily deposits is facilitated by the concurrent passage of cleaning particles and a non-agglomerating drying agent therethrough in a propelling gas stream. In cycling cleaning operations, the preliminary injection of drying agent into the conduit prior to said concurrent use of cleaning particles and drying agent further enhances the overall in-situ cleaning operation.
