  • Calcium removal optimisation
    Patent number: 11242491
    Abstract: A process for optimising the removal of calcium from a hydrocarbon feedstock in a refinery desalting process, the refinery desalting process comprising the following steps: (a) mixing one or more wash water streams with one or more hydrocarbon feedstock streams; (b) at least partially separating the wash water from the hydrocarbons in a refinery desalter; and (c) removing the separated water and hydrocarbons from the refinery desalter as one or more desalted hydrocarbon streams and one or more effluent water streams; the process optimisation comprising: (i) providing at least one x-ray fluorescence analyser at at least one point in the refinery desalting process; (ii) measuring the concentration of calcium at the at least one point in the process using the at least one x-ray fluorescence analyser; and (iii) optionally adjusting at least one process condition of the refinery desalting process in response to the calcium concentration measurement in step (ii).

  • Removing contaminants from crude oil
    Patent number: 10883054
    Abstract: A method comprises correlating—in a system which comprises a non-aqueous phase comprising a hydrocarbon fluid, and an aqueous phase—partitioning levels of a basic contaminant and/or an acid of interest into the aqueous phase with the pH of the aqueous phase. The partitioning levels of the basic contaminant and the acid of interest, as well as the pH of the aqueous phase, are obtained under conditions which are representative of those used in a partitioning process in which a basic contaminant is removed from a hydrocarbon fluid. The correlations may be used in a method for selecting an acidic environment for use in a partitioning process, for estimating corrosion risk downstream of a partitioning process, or for controlling a partitioning process.

  • Sample conditioning
    Patent number: 10436677
    Abstract: A process for analyzing a hydrocarbon stream comprises: withdrawing a hydrocarbon sample from a hydrocarbon stream; passing the hydrocarbon sample to an analysis device at a target temperature of greater than 120° C. and a target flow rate of greater than 20 liters per minute; and returning the hydrocarbon sample to the hydrocarbon stream. The process may be used for the on-line analysis of crude oil, in order to optimize a refinery operation.

  • Desalting Method and Apparatus
    Publication number: 20180086986
    Abstract: A method for optimizing a desalting process in which a hydrocarbon feedstock is passed to a desalter through a line under a set of conditions, the hydrocarbon feedstock containing a hydrocarbon fluid, water and a salt, said method comprising: obtaining spectra of the hydrocarbon feedstock under a plurality of environments in the line; comparing the spectra; and based on the comparison of the spectra, either modifying or maintaining the set of conditions under which the hydrocarbon feedstock is passed to the desalter; wherein the spectra are obtained using neutron backscattering.
