20090159427 | Partial electro-hydrogenation of sulfur containing feedstreams followed by sulfur removal - This invention relates to the partial hydrogenation of sulfur containing petroleum feedstreams by electrochemical means. The partially hydrogenated feedstream is then conducted to processes for either conversion and removal of at least some of the sulfur-containing species from the electrochemical desulfurization process or adsorption and removal of at least some of the sulfur-containing species from the electrochemical desulfurization process. | 06-25-2009 |
20090159503 | Electrochemical treatment of heavy oil streams followed by caustic extraction or thermal treatment - This invention relates to the electrochemical conversion of dibenzothiophene type molecules of petroleum feedstreams to mercaptans that can then be removed, in one embodiment, by caustic extraction. In another embodiment, the mercaptans can be thermally decomposed, removing sulfur as hydrogen sulfide. The conversion of dibenzothiophenes to mercaptans is performed by electrochemical means without the required addition of hydrogen and in the substantial absence of water. | 06-25-2009 |

20100038290 | POLYALKYL SUCCINIC ACID DERIVATIVES AS ADDITIVES FOR FOULING MITIGATION IN PETROLEUM REFINERY PROCESSES - The present application provides a method for reducing fouling, including particulate-induced fouling, in a hydrocarbon refining process including the steps of providing a crude hydrocarbon for a refining process; adding a polyalkyl succinic acid derivative additive. The additive can be complexed with a boronating agent, such as boric acid, to yield a boron-containing polyalkyl succinic acid derivative. | 02-18-2010 |
20100050741 | Comprehensive two-dimensional gas chromatography method with one switching valve as the modulator - The present invention is an improvement to two-dimensional comprehensive gas chromatography. The improvement is a one valve switching modulator connecting the two separation columns. The valve includes either a two position eight-port valve or a two position twelve-port valve, and two transfer lines. | 03-04-2010 |
20110209525 | Simulation Distillation by Comprehensive Two-Dimensional Gas Chromatography - A method to simulate distillation of a petroleum stream by comprehensive two-dimensional gas chromatography including the step of separating said petroleum stream with a two-dimensional gas chromatograph to determine polarity as a function of temperature, and integrating vertically the two-dimensional gas chromatograph at a given temperature to determine signal intensity as a function of temperature. | 09-01-2011 |
20120000792 | Electrochemical Treatment of Heavy Oil Streams Followed by Caustic Extraction or Thermal Treatment - This invention relates to a process for electrochemical conversion of dibenzothiophene type molecules of petroleum feedstreams selectively to mercaptan compounds that can then be more easily removed from the electrochemically treated product stream by either caustic extraction or thermal decomposition of the thiol functionality to hydrogen sulfide. The conversion of dibenzothiophenes to mercaptans is performed by electrochemical means in the substantial absence of hydrogen and in the substantial absence of water. | 01-05-2012 |
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 |
