This disclosure describes methods to separate solids from liquids in a production facility. A process separates components in the process stream by applying non-condensable media to create density differences and then using a mechanical device to separate the solids from the liquids based on the density difference. The process produces the liquids and solids, which may be further processed to create valuable animal feed products.

A method for counter-current liquid-liquid extraction in a sub-millimeter conduit is implemented from an initial liquid drop stream. The stream has alternating drops of a first liquid, and a second liquid less wetting than the first liquid and immiscible with the first liquid. One of the liquids includes a component to extract towards the other liquid. A first pressure gradient applied along the conduit generates a visco-inertial flow displacing a first drop stream volume according to the first gradient and generating a film of first liquid displaced along the opposite orientation, the film being located between the drops of second liquid and the conduit. The application of the first pressure gradient is stopped. A second pressure gradient is applied along the conduit, in the opposite orientation to generate a viscous-capillary flow displacing a second volume of according to the second gradient and application of the second pressure gradient stops.

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.

A method for prophylaxis or treatment of a graft's rejection of a recipient, driven and adjusted by a microprocessor-based controller. Provided is a fluid circuit comprising a first container configured to receive a transplant component and a second container configured to receive an apoptotic component. Provided is a separator configured to associate with the fluid circuit and separate whole blood into a red blood cell component, a plasma component, and a white blood cell component. Whole blood is directed into the fluid circuit and the separator. The whole blood is separated into the red blood cell component, the plasma component, and the white blood cell component. A first portion comprising the transplant component of the white blood cell component is directed to the first container. A second portion of the white blood cell component is directed to the second container and the second portion is rendered apoptotic.

A process and a preparation plant prepares methacrolein from formaldehyde and propionaldehyde, in presence of water and a homogeneous catalyst based at least on an acid and a base. A reaction mixture is introduced into a methacrolein workup plant and separated in a first distillation column, into a first distillation mixture in a gas phase at the top and a second distillation mixture in a liquid phase at the bottom. The first distillation mixture is condensed and, in a first phase separator, the organic phase and the aqueous phase of the condensate are separated from one another. The aqueous phase is introduced into a second distillation column, that is not part of the methacrolein workup plant, and is separated into a third distillation mixture in a gas phase at the top and a fourth distillation mixture at the bottom. The third distillation mixture is introduced into the methacrolein workup plant.

A separation system for separating components of a flow of multi-phase fluid includes an elongate separator vessel oriented on an incline to define a lower inlet end having an inlet for receiving the fluid flow, a raised outlet end, and an inclined top inner surface extending from the inlet end to the outlet end. The system includes a lower weir plate positioned above the inlet end and an upper weir plate positioned below the outlet end having an upper edge defining a liquid level within the separator vessel, thereby allowing a lighter fluid component to flow over the upper edge into a upper section located forwardly of the upper weir plate. The system also includes a clear water pipe with a withdrawal opening positioned below the upper weir plate. The incline of the separator vessel is adjustable in accordance with the composition of the multi-phase fluid.

A conduit assembly for a separation device is described herein. The conduit assembly includes a first conduit segment, a second conduit segment, and a removable flow control insert or cartridge, which may be easily installed and uninstalled without removing other components of the conduit assembly from the separation device. The flow control insert may be installed within a top opening of the second conduit segment and includes a projection that extends into the conduit assembly and obstructs or restricts fluid flow at the juncture between the first and second conduit segments.

A molded body includes a shape memory material. The molded body has a three-dimensional surface structure which, in a permanent shape, at least in part has a superhydrophobic surface and/or a hydrophobic surface, on which water droplet contact angles of 120° to 150° are found.

A separation device configured to separate light and heavy components of an effluent mixture. The separation device includes a separation tank, an inlet discharge, an outlet diffuser, and a baffle. The separation tank includes a tank reservoir for containing the effluent mixture during separation, with light components configured to migrate upwardly toward a static water line and heavy components configured to sink adjacent the bottom. The inlet discharge is located within the tank reservoir to supply effluent mixture to the separation tank. The outlet diffuser is spaced from the inlet discharge and located within the tank reservoir to receive a heavy component of the effluent mixture after separation. The baffle is located within the tank reservoir to separate the inlet discharge from the outlet diffuser. The baffle presents a baffle opening adjacent the static water line.
