Patent number: 10633600Abstract: Methods, systems and designs are provided for removing mercury from crudes. Crude oil containing a synthetic reducing agent is heated to a temperature above 100° C. and held at that temperature for a specified period of time to convert all of the forms of mercury in the oil into the elemental mercury form. The elemental mercury is then stripped from the crude oil by e.g., flashing the hot oil and/or contacting it with a gas phase.Type: GrantFiled: August 1, 2018Date of Patent: April 28, 2020Assignees: ConocoPhillips CompanyInventors: Lars T. Lambertsson, Charles J. Lord, III, Erik L. Björn, Wolfgang Frech

The elemental mercury is then stripped from the crude oil by e.g., flashing the hot oil and/or contacting it with a gas phase. This process transfers the elemental mercury from the oil phase into the gas phase. Elemental mercury can then be removed from the gas phase by methods such as condensation, precipitation, or absorption either alone or in combination.Type: GrantFiled: February 6, 2014Date of Patent: February 21, 2017Assignee: ConocoPhillips CompanyInventors: Charles J Lord, III, Lars T Lambertsson, Erik L.

Patent number: 8936686Abstract: A method of selecting a mercury-contaminated solid surface followed by heating a cleaning solution to a temperature less than 100° C. The cleaning solution can contain hydrocarbon oil and one or more organic sulfur compounds. Afterwards, the heated cleaning solution is contacted with the mercury-contaminated solid surface to remove the mercury contamination.Type: GrantFiled: September 8, 2011Date of Patent: January 20, 2015Assignee: ConocoPhillips CompanyInventors: Charles John Lord, III, Lars Torsten Lambertsson, Erik Lennart Bjorn, Wolfgang Frech

Patent number: 4726678Abstract: Unitary receptacle and contact pieces for vaporization and spectroscopic analysis of an analysis sample. Receptacle means are incorporated in the receptacle reception of the sample. The contact pieces are formed integrally with the receptacle for connection of the reception means to an electrical supply unit to enable the sample to be heated. The reception means may constitute a bore in the receptacle, a cup for containing an analysis sample engageable in the bore and additional contact pieces formed integrally with the cup for connection of the cup with a current supply unit therefor.Type: GrantFiled: September 26, 1986Date of Patent: February 23, 1988Assignee: Ringsdorff-Werke GmbHInventors: Bruno Hutsch, Wolfgang Frech

Patent number: 4138043Abstract: A gooseneck for a hot chamber die casting machine, which gooseneck includes a compression chamber having a pressure piston movably mounted therein with the compression chamber being in communication witha conical mouthpiece by way of transverse and vertical passages. The mouthpiece is arranged in a neck projecting from the gooseneck with the entire gooseneck being forged from a heat-resistant tool steel. The area of the casting container which includes the compression chamber and the vertical passage has in cross-section the form of two cylinders with parallel axes. A heating device may be provided for heating the projecting neck portion forming the mouthpiece of the gooseneck and a further heating construction may be provided for heating the injection nozzle to prevent the solidification of a melt therein.Type: GrantFiled: January 5, 1977Date of Patent: February 6, 1979Assignee: Firma Oskar Frech WerkzeugbauInventor: Wolfgang Frech
