Utility
Method for selective extraction of surfactants from crude oil
4 Jan 21
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.

Utility
Methods of using nondestructive material inspection systems
4 Jan 21
For method of utilizing a nondestructive evaluation method to inspect a steel material comprising at least one hysteretic ferromagnetic material and/or at least one nonhysteretic material to identify one or more material conditions and/or one or more inhomogeneities in steel material, the method can comprise the steps of: interrogating the hysteretic ferromagnetic material and/or the nonhysteretic material with an input time varying magnetic field; scanning the steel material and detecting a magnetic response and/or acoustic response over time from the hysteretic ferromagnetic material and/or the nonhysteretic material; determining a time dependent nonlinear characteristic of the received magnetic response and/or acoustic response; and correlating the time dependent nonlinear characteristic of the received magnetic response and/or acoustic response to the one or more material conditions and/or one or more inhomogeneities in steel material.
