Abstract: A method for selective extraction of naphthenic acids from an acidic crude oil, including: providing an acidic crude oil including naphthenic acids and having a total acid number (TAN) greater than 0.4; mixing the acidic crude oil with a first aqueous solution including water and a weak base to extract a portion of naphthenic acids from the acidic crude oil thereby creating a second aqueous solution containing a mixture of the portion of naphthenic acids, the water and the weak base in an emulsion; separating the second aqueous solution from the emulsion; wherein the second aqueous solution contains an additional portion of the acidic crude oil; adding a salt to the second aqueous solution, thereby causing the additional portion of the acidic crude oil to separate from the second aqueous solution; removing the additional portion of the acidic crude oil from the second aqueous solution; and extracting the portion of the naphthenic acids from the second aqueous solution.

Abstract: A species extraction apparatus for liquid-based extractions is disclosed herein. The apparatus comprises a body supporting a matrix structure comprising cellular units. The apparatus is configured to uptake an absorptive liquid, and the absorptive liquid can remove at least one species from a working fluid that contacts the apparatus. In certain embodiments, the at least one species can be CO2, and the absorptive liquid can be liquid water-free tetraethylenepentamine (TEPA). The apparatus is advantageously manufacture using additive manufacturing techniques.

Abstract: Systems and methods are provided for regenerating a bed containing absorbed and/or adsorbed CO2 using a low value steam stream. The steam stream can have a pressure of 10 kPa-a to 50 kPa-a and a temperature of 46° C. to 81° C. The steam stream can be used to displace CO2 from the bed, resulting in formation of a low pressure stream including water vapor and CO2. The stream containing water vapor and CO2 is then passed through a liquid ring pump that includes an associated ring cooler. The ring pump provides the suction necessary to draw the low value steam stream through the bed to displace the CO2. Due to the nature of operation of the liquid ring pump, the majority of water in the steam containing H2O and CO2 can be removed within the liquid ring pump, resulting in production of a stream comprising 90 vol % or more of CO2 at a pressure of 90 kPa-a or more. An example of a bed that can be regenerated using a low value steam stream is a bed that corresponds to a liquid amine that is coated on/covering/impregnated into a porous solid, so that the liquid amine remains substantially in place during a cycle of sorption and desorption of CO2.

Abstract: Capsules, systems and methods for delivering chemical components to multiphase environments are disclosed. The systems and methods utilize delivery capsules within which the chemical components are encapsulated. The chemical components may be corrosion inhibitors or biocides and the multiphase environment an oil/water environment, for example, within an oil transport pipeline. The systems and methods allow delivery of the capsules to targeted areas of the multiphase environment, for example, to a water phase or a water/metal interface.
