Abstract: Embodiments provide a method of controlling a flow of pipeline fluid through a pipeline pig that includes a bypass channel and at least one relief channel extending therethrough. The method includes (a) inserting the pipeline pig into a pipeline through which the pipeline fluid is flowing, (b) increasing a differential pressure established in the pipeline fluid between a trailing end and a leading end of the pipeline pig such that the differential pressure sequentially reaches a pre-selected minimum relief pressure, a pre-selected maximum relief pressure and a pre-selected minimum bypass pressure, (c) opening the at least one relief valve to permit the pipeline fluid to flow through the relief channel when the differential pressure reaches the pre-selected minimum relief pressure (d) closing the at least one relief valve to restrict the flow of pipeline fluid through the relief channel when the differential pressure reaches a pre-selected maximum relief pressure, and (e) opening a bypass valve to permit the pipeline fluid to flow through the bypass channel when the differential pressure reaches the pre-selected minimum bypass pressure.

Abstract: The present invention relates to online analysis of crude oil from desalting processes. Online analysis of the crude oil that has been desalted will allow for real time adjustments to process operating parameters such that the salt concentration of the crude oil is maintained within acceptable parameters. This online analysis can yield a more efficient process, reduce energy consumption of the desalting process, and maintain corrosion rates within acceptable limits

Abstract: Provided here is a system for controlling salt concentration in a dry crude stream using an online analysis of crude oil streams from desalting processes. This online analysis allows for real time adjustments to process operating parameters such that the salt concentration of the crude oil is maintained within acceptable parameters. This online analysis can yield a more efficient process, reduce energy consumption of the desalting process, and maintain corrosion rates within acceptable limits.

Abstract: A pipeline pig includes a plurality of relief channels and a bypass channel extending therethrough. To regulate a speed of the pipeline pig, relief valves within the relief channels open when a differential pressure between upstream and downstream ends of the pipeline pig reaches a pre-selected minimum relief pressure. If the differential pressure reaches a pre-selected maximum relief pressure, such as when the pipeline pig encounters an obstruction, the relief valves close to allow the differential pressure to further increase to clear the obstruction. If the further increase in differential pressure is insufficient to clear the obstruction and the differential pressure reaches a pre-selected minimum bypass pressure, a bypass valve opens to permit fluid flow through the bypass channel while the relief valves are closed. Flow through the bypass channel operates to reduce turbulence and permit production through the pipeline if the pipeline pig becomes stuck and obstructs the pipeline.
