Systems and methods to separate water and remove solids from a pre-treated and unfiltered renewable feedstock at or separate from a refinery. Such systems and methods may be used to provide a reduced-contaminant and reduced-solid renewable feedstock for further refining.

A method of treating contaminated materials such as oil and gas production waste sludges to recover crude oil hydrocarbons. The method includes the inversion of water-in-oil emulsions, and subsequent separation steps. These may involve the separation and removal of asphaltenes, petroleum waxes and/or solid particles from the crude oil hydrocarbons. The treatment method uses the physical phenomena of hydrodynamic cavitation and hydraulic shock, which produce different effects upon a mixture of water and the contaminated material being treated. These are deployed either as single or combined stage(s) of treatment or as a repeated series of single/combined treatment stages, with or without additional processing operations between each single/combined treatment stage. The method may be implemented with suitable plant including hydrodynamic cavitation units (103, 106) and hydraulic shock units (104, 107), followed by separators (105, 108).

Systems and methods for separation of hydrocarbon containing fluids are provided. More particularly, the disclosure is relevant to separating fluids having a gas phase, a hydrocarbon liquid phase, and an aqueous liquid phase using indirect heating. In general, the system uses a first three-phase gas separation. The gas stream separated out is cooled with the resulting hydrocarbon condensates reintroduced to the stream of hydrocarbon-liquid phase that was separated from the fluid. The resulting combined stream can be cooled or heated as necessary.

A system for stabilizing a hydrocarbon feedstock includes a High Pressure Separation (HPS) unit in fluid communication with a feedstock inlet. The HPS unit includes an oil outlet. The system includes a heated Low Pressure (LP) separator unit downstream from and in fluid communication with the oil outlet of the HPS unit. The heated LP separator unit includes an oil outlet. The system includes a heat exchanger positioned between the HPS unit and the heated LP separator unit.

A Filter for the removal of water from oil, the filter includes a distillation element having an inlet pipe that in one end is to be fluidly connectable to a reservoir of oil to be filtered, and in the other end being fluidly connected to a distillation head, said distillation head including a plurality of compressing tubes for injecting under pressure said oil into an evaporation chamber, whereby eventual water within the oil droplet evaporates from said decompressed oil, the filter further including a tubular core with a plurality of apertures and a hollow interior, said core having an open end for fluid communication with the hollow interior, a length of yarn wound around an outer surface of the core, wherein the filter further includes a device for blowing air or an inert gas into the evaporation chamber for removal of the water vapor during use of the filter. A method of manufacturing such a filter, as well as a method of removing water of is also disclosed. The water removal unit is part of a modular system, which makes the whole filter unit scalable within fixed steps. When water removing block with attached start block and end block, are stacked upon each other, and connected to filter unit, it becomes scalable complete cleaning equipment. Pump and motor must be adapted to each configuration.

An automated process and accompanying apparatus simultaneously separates and measures the flow rate of any multiphase mixture of immiscible fluids. Such separation and measurement can occur in a single vessel, or multiple vessels. Liquid levels, together with a material balance analysis, are utilized to determine constituent liquid flow rates. The vessel(s) can be remotely operated and monitored in real time, while also allowing for automated or manual calibration.

Separation of particles or droplets from a host fluid may be achieved using a transducer and/or reflector that is a thin, non-planar structure. The thin non-planar structure improves operation of an acoustic standing wave generated by an acoustic transducer. The structure may operate as a pressure release boundary and may be constructed as plastic film.

A method, device and a system for extracting oil from a paste of oily fruit by exposing the oily fruit paste to vacuum.

Systems and methods to enhance the removal of inorganic contaminants, including metals, from hydrocarbon feedstocks at a refinery. One or more embodiments of such systems and methods may be used to provide a renewable hydrocarbon feedstock having a reduced amount of metal contaminants. The reduction of metal contaminants in the renewable hydrocarbon feedstock mitigates catalyst fouling and/or deactivation during downstream refinery processing of the renewable hydrocarbon feedstock.

An oil/water separating device for removing oil-containing constituents from an oil/water mixture, including a main filter which is configured for separating oil-containing constituents from the oil/water mixture, where an oil/water mixture to be purified is supplied to the main filter from a top housing via a condensate line and is removed from the oil/water separating device after passing through the main filter, and the oil/water separating device is configured for supplying and removing these liquids in accordance with the hydrostatic principle, where the top housing is disposed above the main filter, wherein the distance between the top housing and the main filter is selected so as to result in a hydrostatic pressure on the main filter of at least 0.05 bars.
