Abstract
The present invention comprises a method for removing residual hydrocarbon fluids from pipe systems by contacting the hydrocarbon with a solution containing a hydrocarbon-stripping agent which is capable of decreasing the wetting characteristics of the residual hydrocarbon on the internal surfaces of the pipe system whereby the film retracts from the surface and forms droplets which are thereafter removed with the water solution. Specific hydrocarbon-stripping agents are disclosed.
