Abstract: A method is provided for determining the solubility parameters for a process stream via the joint use of turbidimetric detection of asphaltenes flocculation, which is used to determine and detect the onset flocculation of asphaltenes of the process stream, and a refractive index to determine the process stream solubility parameters such as the solubility blending number and insolubility number.

Abstract: Biological source oils, including, but not limited to, algae oil, stabilize the presence of asphaltenes in petroleum feedstocks, such as crude oil, to help avoid or prevent fouling and/or corrosion in the production, transferring and processing of the petroleum feedstocks. Chemical additives such as phenol-based resins, and reaction products or combinations of long chain alpha-olefins and/or small chain aldehydes and/or long chain alkyl phenate sulfides and/or metal oxide-based colloidal hydrocarbon-based nanodispersions, may also stabilize the presence of asphaltenes in petroleum feedstocks. By “stabilizing” is meant keeping the asphaltenes in solution in the petroleum feedstocks.

Abstract: Biological source oils, including, but not limited to, algae oil, stabilize the presence of asphaltenes in petroleum feedstocks, such as crude oil, to help avoid or prevent problematic issues caused by the asphaltenes, such as sludges, plugging, deposits, fouling and/or corrosion in the production, transferring and processing of the petroleum feedstocks. Chemical additives such as phenol-based resins, and reaction products or combinations of long chain alpha-olefins and/or small chain aldehydes and/or long chain alkyl phenate sulfides and/or metal oxide-based colloidal hydrocarbon-based nanodispersions, may also stabilize the presence of asphaltenes in petroleum feedstocks.

Abstract: A process for refining crude oil can be controlled to mitigate fouling by deploying a refractive index probe at a location suitable for making a crude oil stability determination, wherein the crude oil stability determination is relevant to controlling the refining process; making a measurement of crude oil stability; and then controlling the process for refining crude oil by maintaining the process or implementing a change to the process, based upon the determination of crude oil stability. This concept can also be applied to transporting, blending, and storing crude oil.

Abstract: Industrial fluids may be monitored at the site of each industrial fluid by introducing a sample of the industrial fluid into a device employing a detection technique for detecting at least one composition within the sample. The detection technique may be or include surface enhanced Raman scattering (SERS), mass spectrometry (MS), nuclear magnetic resonance (NMR), ultraviolet light (UV) spectroscopy, UV spectrophotometry, indirect UV spectroscopy, contactless conductivity, laser induced fluorescence, and combinations thereof. In one non-limiting embodiment, a separation technique may be applied to the sample prior to the introduction of the sample into the device for detecting the composition.

Abstract: Industrial fluids can be monitored by employing differential ion mobility spectrometer to sample the industrial fluids. This process may also include controlling an industrial device or an industrial process using the results of the output from the field asymmetric ion mobility spectrometer. The process may also include employing a device to condition the sample prior to introducing the sample into field asymmetric ion mobility spectrometer.
