Abstract:
1. A recirculating flow loop comprising: (a) a tubular fluid intake nozzle having a first intake nozzle end extending radially inwardly through a first side of a pipeline having a petroleum fluid flowing through the pipeline from an upstream end of the pipeline to a downstream end of the pipeline and a second intake nozzle end external to the pipeline, wherein the first intake nozzle end is sealingly closed, wherein the intake nozzle has an inlet opening facing upstream and located concentrically with a flow axis of the pipeline, wherein the inlet opening penetrates a wall of the intake nozzle positioned within an interior of the pipeline, and wherein the fluid intake nozzle removes approximately 20-30% of the fluid flowing through the pipeline to extract a representative sample of the fluid flow; (b) an intake piping having a first leg attached to the second intake nozzle end and a second leg joined at an angle to the first leg where the second leg runs approximately parallel the pipeline; (c) a pump having an inlet and an outlet, wherein the inlet is attached to the second leg of the intake piping; (d) an injection pipe attached to the outlet of the pump at a first end of the injection pipe, the injection pipe including a detector module mounted adjacent the pump outlet, wherein the detector module has a measurement probe radially extending through a centerline of the injection pipe; and (e) a tubular injection nozzle having a first injection nozzle end attached to a second end of the injection pipe and a second injection nozzle end extending radially inwardly through the first side of the pipeline upstream of the fluid intake nozzle, wherein the second injection nozzle end is sealingly closed, wherein the injection nozzle has two diametrically opposed injection outlets penetrating a wall of the injection nozzle, wherein the two injection outlets are positioned within the interior of the pipeline and oriented transverse to a flow axis of the pipeline, wherein the two injection outlets are further oriented perpendicular to the inlet opening, and wherein the two injection outlets are configured such that the fluid exiting from them contacts the pipeline substantially near the center of opposing side walls of the pipeline.
