| 20090282897 | METHOD OF DETERMINING PHYSICO-CHEMICAL PROPERTIES OF A PETROLEUM SAMPLE FROM TWO-DIMENSIONAL GAS CHROMATOGRAPHY - A method of determining physico-chemical properties of a petroleum sample from two-dimensional gas chromatography. The amounts of molecular compounds present in the sample are determined by means of two-dimensional gas chromatography. At least one physical property, such as the octane number, is then determined from these amounts. A previously calibrated relation connecting the physical property to the amounts is used to this end. | 11-19-2009 |
| 20130061658 | METHOD FOR DETERMINING METHANOL CONTENT IN CRUDE OILS - A test method for the determination of methanol in crude oils to levels as low as 0.5 ppm is disclosed. The method includes extracting methanol into a water phase from a test sample of the crude oil forming a test sample extract. The method further includes extracting methanol into a water phase from a reference sample of the crude oil forming a reference sample extract, wherein the reference sample having a predetermined amount of methanol added thereto. The method further includes measuring the methanol content in the test sample extract and the methanol content in the reference sample extract. The method also includes determining the methanol content of the crude oil based upon the methanol content in the test sample extract and the methanol content in the reference sample extract. | 03-14-2013 |
| 20130125619 | MEASUREMENT OF CARBON TO HYDROGEN RATIO IN HYDROCARBONS - The ratio of carbon to hydrogen in hydrocarbon samples is determined using gas chromatography and atomic emission detection. Comparison of the carbon to hydrogen ratio from different samples allows for qualitative determination of relative hydrogen content. Establishing a carbon to hydrogen ratio for a reference sample allows a further quantitative determination of carbon to hydrogen ratio. | 05-23-2013 |
| 20140157870 | Measuring Properties and Amount of Producible Oil in Shale-Oil Reservoir Samples - The subject matter of the present disclosure is directed to developing a method of measuring the amount of producible oil and the producible oil saturation in shale-oil reservoirs using sample source rock. Further, the physical and chemical properties and amounts of producible oil in shale-oil reservoir samples may be determined. First and second solvents are applied to a sample source rock to extract petroleum from the sample source rock. The extracted source rock, the twice-extracted source rock, and the first and second extracted petroleum may be analyzed to determine the characteristics and properties of the reservoir rock. | 06-12-2014 |
| 20140165701 | ANALYSIS OF HYDROCARBON LIQUID AND SOLID SAMPLES - Systems and methods are provided for analysis and/or profiling of petroleum samples. The systems and methods allow for compositional analysis of samples using techniques that can be implemented outside of a laboratory setting, such as in a refinery or even at a petroleum or hydrocarbon source. The techniques are enabled by using desorption electrospray ionization as a method for generating ions for detection by mass spectroscopy. Desorption electrospray ionization can be used to generate ions for detection from a liquid or solid petroleum (or other hydrocarbon) sample with minimal sample preparation. For solid samples, the technique can also be used to identify changes in composition of a petroleum sample relative to a dimension of the solid sample. | 06-19-2014 |
| 20140174151 | METHOD TO ANALYZE ALKYLATE PRODUCTS - We provide an extracted conjunct polymer naphtha (45), comprising a hydrogenated conjunct polymer naphtha, from a used ionic liquid catalyst, having a final boiling point less than 246° C.(475° F.), a Bromine Number of 5 or less, and at least 30 wt % naphthenes. We also provide a blended alkylate gasoline (97 comprising the extracted conjunct polymer naphtha (45), and integrated alkylation processes to make the extracted conjunct polymer naphtha (45) and the blended alkylate gasoline (97). We also provide a method to analyze alkylate products, by determining an amount of methylcyclohexane in the alkylate products (80). | 06-26-2014 |
