A separation tank for crude oil. Fluid enters an inlet section of a center column of the tank via an offset inlet pipe so the fluid enters swirling. Solids that settle in the inlet section are removed by a center column drain and a solids removal system. Free gas rises and exits from the top of the tank. Liquid flows out of the center column via a diffuser that spirals the fluid evenly toward the wall of the tank where oil coalesces and wicks upward. Liquid flows downward around two flow diverting baffles where more oil coalesces and wicks upward via an oil conduit into the oil layer. The water flows under the lower flow diverting baffle and exits the tank through the outlet section. A large circular oil collector weir uniformly removes oil from the oil layer. Interface draw offs located below the oil-water interface remove excess BS&W.

The present invention provides a system and method for purifying vanadium pentoxide. Industrial grade vanadium pentoxide is converted to vanadium oxytrichloride by low temperature fluidizing chlorination, wherein chlorinating gas is preheated via heat exchange between fluidizing gas and chlorination flue gas, and an appropriate amount of air is added to enable a part of carbon powder to combust so as to achieve a balanced heat supply during the chlorination, thereby increasing the efficiency of chlorination and ensuring good selectivity in low temperature chlorination. The vanadium oxytrichloride is purified by rectification, and then subjected to plasma oxidation, thereby obtaining a high-purity vanadium pentoxide product and chlorine gas. The chlorine gas is returned for low temperature chlorination. The system and method have advantages of favorable adaptability to raw material, no discharge of contaminated wastewater, low energy consumption and chlorine consumption in production, stable product quality, etc.

A vortex reservoir for separation of an aerated portion of a hydraulic fluid includes an upper chamber and a lower chamber, in fluid communication with the upper chamber, having a lower chamber sidewall. The lower chamber includes a lower lower chamber and an upper lower chamber. The lower chamber includes a lower chamber partitioning plate. The lower chamber partitioning plate is located between the lower lower chamber and the upper lower chamber. The lower lower chamber is in fluid communication with the upper lower chamber via a gap between the lower chamber partitioning plate and the lower chamber sidewall.

A wellbore gas separator having a pair of helical ramps. The separator ingests a liquid-gas solution, and a pump draws the solution into a first course between the pair of ramps. As centrifugal force is imparted upon the solution prior to the pump inlet, gas is forced out of solution. The liquid portions of the solution may fall into a dead space prior to the pump inlet. Gaseous portions enter into a second course between the pair of ramps and escapes, unimpeded, up the separator before being released into an annulus of a wellbore.

Processes herein may be used to thermally crack various hydrocarbon feeds, and may eliminate the refinery altogether while making the crude to chemicals process very flexible in terms of crude. In embodiments herein, crude is progressively separated into at least light and heavy fractions. Depending on the quality of the light and heavy fractions, these are routed to one of three upgrading operations, including a fixed bed hydroconversion unit, a fluidized catalytic conversion unit, or a residue hydrocracking unit that may utilize an ebullated bed reactor. Products from the upgrading operations may be used as feed to a steam cracker.

The present invention relates to a method and/or device for improving the separation behaviors and performance of aqueous two-phase system (ATPS) for the isolation and/or concentration of one or more target analytes from a sample. In one embodiment, the present method and device comprise ATPS components within a porous material and one or more phase separation behavior modifying agents that improve the separation behavior and performance characteristics of ATPS, including but not limited to the increasing the stability or reducing fluctuations of ATPS thought the adjustment of total volume of a sample solution that undergoes phase separation, volume ratio of the two phases of the ATPS, fluid flow rates, and concentrations of ATPS components.

An oil tank assembly for a gas turbine engine may include an oil tank having an upper compartment and a lower compartment. A baffle may separate the upper compartment of the oil tank from the lower compartment of the oil tank. A de-aerator may be included, where the de-aerator includes an oil inlet, a de-aerator outlet, and an air vent. The de-aerator may be configured to separate air from oil in an air-oil mixture such that the oil flows through the de-aerator outlet and such that the air flow through the vent. Further, the de-aerator may include a fill port for receiving oil.

A crude oil demulsification system includes a vessel. A cyclonic separator is disposed outside the vessel. The cyclonic separator is configured to receive and separate phases of a multi-phase fluid stream into a gaseous stream and a liquid stream that includes a first liquid phase and a second liquid phase by inducing cyclonic flow. A heat exchanger is fluidically connected to the cyclonic separator. The heat exchanger is disposed outside the vessel, and is configured to receive the liquid stream and to heat the liquid stream by exchanging heat with a heating medium flowed through the heat exchanger. An electrostatic coalescer is fluidically connected to the heat exchanger and is disposed inside the vessel. The electrostatic coalescer is configured to receive the liquid stream heated by the heat exchanger and to demulsify the liquid stream by causing coalescence of liquid droplets of one of the first or second liquid phases.
