The spread of an interface between two immiscible fluids during sequential transportation along a pipeline is reduced by controlling the flowrate of the fluids so that they remain in sequence in the pipeline, and injecting upstream of, and through, the interface an emulsion-producing detergent. A pig or cup-andbrush scraper may be used at each end of the emulsion zone.
