ABSTRACT:
A system for injecting fluid additive into a fluid transmission pipeline including a branch conduit in communication with the pipeline, a pump in the branch conduit for raising the pressure of fluid withdrawn from the pipeline, and an eductor having a branch passage in communication with the additive fluid for withdrawing the additive fluid from a source without increasing the pressure of the additive fluid to the branch conduit pressure or the nominal pipeline fluid pressure. A mixture of pipeline fluid and additive fluid are reinjected through an annular dispersion chamber interposed in the main pipeline. The additive fluid may be metered by a positive displacement flow meter or a metering valve which throttles the flow of additive fluid from a pressurized source.
