Abstract: Systems and methods for crude oil desalting technology are provided. More specifically, systems and methods for the usage of waste heat from compression to treat high salinity water are provided. The systems and methods generate recycled water streams for desalter treatment. The systems and methods can treat high salinity waters from desalters and dehydrators. The high salinity streams are introduced to the compressed gas streams, where the waste heat causes the water portion of the water streams to evaporate, resulting in a fully or near-saturated gas stream and a concentrated waste water stream. The saturated gas streams are cooled and condensed, and low TDS water is separated from the gas stream in knockout drums. The low TDS water can be reintroduced to the desalting system as wash water, generating a circular water reuse.

Abstract: A method to reduce the generation of waste water comprising the steps of withdrawing a formation water stream from production equipment; introducing the formation water stream to a forward osmosis unit, where the forward osmosis unit comprises a semipermeable membrane, where the formation water stream is introduced to a draw side of the semipermeable membrane; withdrawing a surface water feed from a waste water collection pit, the surface water feed comprises water and contaminants; introducing the surface water feed to the forward osmosis unit, where the surface water feed is introduced to a feed side of the semipermeable membrane; separating the water in the surface water feed through the semipermeable membrane, where the water travels from the feed side to the draw side due to osmotic pressure; withdrawing a diluted stream from the draw side of the semipermeable membrane; and introducing the diluted stream to a water-oil separation plant.

Abstract: A flow of a chemical is mixed with a flow of a primary fluid to form a combined fluid, and during mixing a velocity of the combined fluid is maintained at a threshold value so that a resulting mixture of the chemical and primary fluid has a designated homogeneity. The primary fluid is directed to an end of a passage with a venturi like contour that is inside of a mixer, and the chemical is directed to a side passage that extends laterally in the mixer that intersects the passage. A spring loaded valve in the passage maintains the combined flow velocity at the threshold value.

Abstract: An aqueous feed stream having a first total dissolved solids (TDS) level is flowed to a forward osmosis separator. The aqueous feed stream includes seawater. An aqueous draw stream having a second TDS level is flowed to the forward osmosis separator. The second TDS level is greater than the first TDS level. A disposal stream and an injection fluid stream is produced by the forward osmosis separator by allowing water to pass from the aqueous feed stream to the aqueous draw stream through a membrane of the forward osmosis separator based on a difference between the first TDS level and the seconds TDS level. The injection fluid stream is flowed from the osmosis separator to a subterranean formation.

Abstract: A system includes a device disposed within a storage tank. The device includes a cyclonic separator and an electrostatic coalescer. The cyclonic separator is configured to receive and separate phases of a multi-phase fluid stream. The cyclonic separator is configured to induce cyclonic flow of the multi-phase fluid stream to separate the multi-phase fluid stream into a gas stream and a liquid stream. The liquid stream includes a first liquid phase and a second liquid phase. The cyclonic separator is configured to discharge at least a portion of the gas stream and at least a portion of the liquid stream. The electrostatic coalescer is downstream of and fluidically connected to the second outlet of the cyclonic separator. The electrostatic coalescer is configured to demulsify the liquid stream by causing coalescence of liquid droplets of one of the first or second liquid phases.

The plug is rotatably positioned in a hollow space of the valve body. The plug includes two surge suppression openings defining a fluid flow directed to surge suppression. Each of the two surge suppression openings includes a circular plate having a plurality of orifices. The plurality of orifices allows reduction of surge pressure when the water passes the first fluid flow path. The circular plate has a concave or convex geometry.

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: 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.

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.
