An active rotating separator is disclosed, comprising a separator drum arranged to receive multiphase fluid via an upstream end and to deliver separated fluid phases from a downstream end of the drum. An electric motor is installed in the flow through the drum, the motor operable to generate rotation in the fluid flow that passes through the drum, the motor comprising an open rotor permitting through-flow of fluid through the motor.

Transducer assemblies that can be used in acoustophoretic systems are disclosed. The acoustophoretic systems including the transducer assemblies and methods of operating the acoustophoretic systems are also disclosed. The transducer assemblies include a housing, a polymeric film attached to the housing, and a piezoelectric material attached to the polymeric film. The piezoelectric material is not attached to, and does not come in direct contact with, the housing. The piezoelectric material is configured to be driven by a drive signal to create a multi-dimensional acoustic standing wave. The piezoelectric material can be attached to the polymer film by an adhesive coating on the polymer film.

There is provided a method of treating fluid such as tailings from tailings ponds resulting from oil sands production. A fluid treatment separator has a separation chamber having an oil outlet and a water chamber having a water outlet below the height of the oil outlet. A fluid passage connects between the separation and water chambers. The fluid passage is below the height of the water outlet. A centrifuge flow separator is in the separation chamber. A centrifuge flow diffuser is oriented to direct mixed fluids into the centrifuge flow separator. Preferably, the centrifuge flow diffuser is a ring diffuser and the centrifuge flow separator is a centrifuge cone. A fluid treatment system includes a fluid treatment separator and a phase separator and may include multiple fluid treatment separators and phase separators connected in series.

A cyclone type liquid/gas or liquid/liquid separator having separation properties that are stabilized, even when the flow rate and the proportions of the liquid phases for separation vary, by means of a platform situated in the low portion of a cylindrical separation chamber that is fed at its top end via a tangential feed orifice. An installation and a method are also provided for separating the oil and water contained in crude oil, with the help of a cyclone separator.

An integrated fuel water separator filter system is provided. The fuel water separator filter may include a plurality of fuel water separator filters, with at least one fuel water separator filter including electronic sensors to monitor the life of the fuel water separator filter and the amount of water present in the fuel water separator filter. A heater heats the fuel in the fuel water separator filter.

A modularized system for conditioning liquid fuel is provided that includes a mobile trailer and a liquid fuel conditioning skid disposed on and secured to the mobile trailer. The modularized system includes a pre-filter sub-skid disposed on and secured to the liquid fuel conditioning skid that includes a pre-filter configured to remove impurities from a processed liquid fuel prior to providing the processed liquid fuel to a last chance filter. The modularized system includes a last chance filter sub-skid disposed on and secured to the liquid fuel conditioning skid that includes a last chance filter configured to remove impurities from the processed liquid fuel prior to providing the processed liquid fuel to a gas turbine engine. The pre-filter sub-skid and the last chance filter sub-skid are coupled together via piping enabling flow the processed liquid fuel between the pre-filter sub-skid and the last chance filter-sub-skid.

A separator includes a shell: adapted to be vertically oriented in use; a combined wet gas feedstock ingress and separated liquid egress at the bottom of the shell; a separated gas egress at the top of the shell; a first permeable, fluid flow barrier disposed within the shell at the bottom end thereof proximate the ingress and comprising a first medium; a second permeable, fluid flow barrier disposed within the shell atop and proximate to the first barrier and comprising a second medium; and a third permeable, fluid flow barrier dispose within the shell at the top thereof proximate the egress and comprising the first medium, the third barrier being dispose such that there is a gap between the second and third barriers.

An oil stop valve assembly for allowing a flow of water and blocking a flow of oil has a body having an inlet and an outlet, a seat formed adjacent to the outlet of the body, and a float positioned in the body. The float has a specific gravity of between 0.90 and 0.95 so as to be buoyant in water and to sink in oil. The float is away from the seat when a level of water within the body is above the seat. The float is seated in the seat when the level of water in the body is adjacent to the seat. The body is positioned in a container having a fluid inlet and a fluid outlet. The fluid outlet of the container is connected to the outlet of the body.
