  • Patent number: 10315964
    Abstract: According to the present invention, a deuterium-substituted marker for fuel is synthesized through substitution with deuterium so as to have structurally and chemically similar properties to those of a molecule configuring fuel oil. A molecule of the deuterium-substituted marker is significantly similar to the conventional molecule configuring the fuel oil, which may prevent illegal removal of the marker by the fake oil manufacturers. According to the present invention, it is able to pursue public safety and environmental protection from fake oil products, and to prevent national tax evasion, by preventing the illegal mixing of fuel oil to secure a legal distribution of the oil market according to the present invention.

  • Patent number: 10301934
    Abstract: A downhole densitometer is used to determine one or more characteristics of a flowing fluid. The densitometer has one or more downhole x-ray sources and one or more downhole x-ray detectors. A fluid is allowed to flow past the x-ray sources. X-rays emitted by the x-ray sources and that have travelled through the flowing fluid are detected by the x-ray detectors. Characteristics of the flowing fluid are determined based on the detected x-rays. The densitometer may also have reference detectors used to measure a reference signal. The measured reference signal is used to normalize source emissions. The densitometer may be used as a permanent monitor and it may be used in conjunction with other sensors such as a flow-rate sensor or a capacitance sensor. The x-ray source may be, for example, a pyroelectric source, a radioisotopic source, or a traditional x-ray tube source.

  • Patent number: 8887557
    Abstract: Two quantitative separation approaches to fractionate de-asphalted oils (DAOs) into seven classes of compounds (saturates, 1-4+ ring-aromatics, sulfides, and polars). In the first step (named as “SGS”) of present invention, the DAO of a petroleum vacuum resid is separated in to four classes of compounds, namely saturates, aromatics, and sulfides. In this first step of separation, about 3 grams of a DAO can be separated. Whereas in the second step (named as “ARC” separation) of invention, only less than 300 mg of the aromatic fraction obtained in “SGS” (described above) can be further fractionated at very low temperature (about ?40 degrees centigrade) into 4 fractions, namely 1-ring, 2-ring, 3-ring, and 4+-ring aromatics. The present invention protocol is suitable for a wide range of compositionally different DAOs of petroleum vacuum resids.

  • Patent number: 8334142
    Abstract: Closed-loop control of a hydrocarbon process is provided by an analyzer including an instrument configured for measuring a property of the liquid mixture, and having responsivities to concentrations of one of the components, independent of concentrations of others of the components. A temperature detector generates temperature data for the liquid mixture, and a processor captures data generated by the temperature detector and the instrument, and uses the data in combination with a model of responsivities to various concentrations of the components at various temperatures, to determine a temperature compensated concentration of the components while the liquid mixture flows continuously through the analyzer. A process control module including a process model of the hydrocarbon process, is coupled to the analyzer and is couplable to the hydrocarbon process, to receive the temperature compensated concentration and to generate at least one output configured to affect operation of the hydrocarbon process.

    Abstract: A method for detecting a taggant molecular structure in a fluid includes providing a molecularly imprinted polymer sensor device, contacting a molecularly imprinted crosslinked star polymer with the fluid, and correlating a color change in the fluid with the amount of the taggant molecular structure in the fluid. The device has polymer arms attached to a core, and the core has molecular sized cavities adapted to selectively receive and bind displacement molecules having the taggant molecular structure and a colorimetric indicator. The displacement molecule is selectively removed from the molecularly imprinted crosslinked polymer upon exposure to the taggant molecular structure in the fluid thereby indicating the presence of the taggant molecular structure in the fluid based on a loss of color along a length of a housing.
