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.

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: The present disclosure relates to surfactants formed from sulfonation of aromatic ethers. The example surfactant composition may include a sulfonated aromatic ether. The sulfonated aromatic ether may include an aromatic ring with substituents comprising an ether group and a sulfonic acid group or a salt of the sulfonic acid group. The ether group may be represented by the following formula: wherein R1 is a linear or branched alkyl group having from 1 carbon atom to 20 carbon atoms; wherein each R2 is individually a hydrogen or an alkyl group having from 1 carbon atom to 4 carbon atoms; and wherein n is a value from 0 to 8.
