ABSTRACT:
Pipeline capsules, pigs, or other solid objects bypass a pipeline pump station via a bypass system that avoids cycling of the primary fluid flow. The fluid is removed from the main pipeline through perforations in the pipeline wall, transported through the pump and reinjected into the main pipeline downstream from the fluid removal point. Two valves are located in the main pipeline between the fluid removal point and the fluid reinjection point. The first valve is opened in response to the detection of the incoming solid object, allowing it to pass through the valve. The first valve is then closed and the second valve opened to allow the solid object to pass through the second valve and re-enter the main fluid stream.
