Pipeline injector apparatus and method for using same
A method is described for introducing a shear sensitive drag reducing additive material in the form of a synthetic polymer for reducing drag created by a primary petroleum liquid being pumped through a generally cylindrical petroleum pipeline and the like. The method consists of: providing a probe characterized by an elongated tubular member supported on the pipeline and extending generally transversely within the pipeline across a major portion of the interior of the pipeline and on opposite sides of the longitudinal centerline of the pipeline, the tubular member being adapted to be connected to a source of drag reducing additive; causing the additive to pass from the source to the tubular member and through the apertures into the interior of the pipeline in the region of relatively rapid change of velocity of the petroleum so as to thoroughly mix with the petroleum and to reduce viscous drag forces of the petroleum being pumped through the pipeline.
