20100000910 | SYSTEM AND METHOD FOR SEPARATING A TRACE ELEMENT FROM A LIQUID HYDROCARBON FEED - The present invention is generally directed to removing a trace element from a liquid hydrocarbon feed. The liquid hydrocarbon feed, containing the trace element, is mixed with the water along with a hydrocarbon-soluble additive. While being mixed, a compound, which in some cases is preferably insoluble, is formed by the hydrocarbon-soluble additive chemically reacting with the trace element. A phase separation device, such as a desalter or an oil-water separator, receives the oil-water emulsion containing the compound and resolves the mixture to produce the compound, effluent brine, and effluent liquid hydrocarbon with a reduced concentration of the trace element as compared to the liquid hydrocarbon feed. In some embodiments, the present invention is directed to removing elemental mercury from a liquid hydrocarbon feed. A hydrocarbon-soluble sulfur-containing additive, typically an organic polysulfide, is mixed with the liquid hydrocarbon feed and water. The hydrocarbon-soluble, sulfur-containing additive reacts with the mercury, rapidly forming an agglomeration of mercuric sulfide which is then dispensed with the effluent brine or the effluent liquid hydrocarbon. | 01-07-2010 |

20090268868 | DEVICE AND METHOD FOR DETECTING DEPOSITS ON AN INNER SURFACE OF A PASSAGE - A method and device for detecting mercury or other material deposits on an inner surface of an enclosed passage are provided. The device includes a detection unit that is adapted to be transported through the passage, and the detection unit includes a radiation source and an x-ray fluorescence detector. The radiation source is configured to emit a radiation emission toward the inner surface of the passage to excite a portion of the inner surface, and the x-ray fluorescence detector is configured to detect a resulting x-ray emission from the portion of the inner surface to identify a material deposit on the inner surface. The detection unit can identify material deposits at successive positions along a length of the passage and thereby generate a plurality of data points, each data point providing an indication of a material deposit existence for a corresponding position along the length of the passage. | 10-29-2009 |

20120180609 | BEVELLING APPARATUS FOR PIPE RE-FACING MACHINE - In an improvement to a pipe re-facing machine having a rotatable flange plate and a coaxially-mounted collar rotatable with and longitudinally movable relative to the flange plate, a support bracket projects from the flange plate, and a support block is retainingly mounted to and movable relative to the support bracket in an angled radial direction. The support block is adapted to receive a tool holder carrying a cutting element. An actuating mechanism is engageable with the support block such that longitudinal movement of the collar will move the support block relative to the support bracket. The actuating mechanism can thus move the cutting element in an angled direction relative to the axis of a tubular workpiece, thereby enabling machining of a bevelled edge on an annular shoulder of a tubular workpiece non-rotatably mounted to the re-facing machine by longitudinally moving the collar while rotating the flange plate. | 07-19-2012 |
