Patent number: 10746677Abstract: An open cup flash point detector is shown that rapidly increases the temperature of the substance being tested until temperature is close to a theoretical flash point. Thereafter, as temperature is slowly increased, an igniter flame moves in an arc over the upper lip of the test cup while simultaneously a UV sensor senses a wedge-shaped area, also immediately over the upper lip of the test cup. The arc of the igniter flame and the wedge-shaped area do not overlap. By incremental increases in temperature and repeating the arc movement of the igniter flame, the flash point can be detected by the UV sensor.Type: GrantFiled: June 12, 2019Date of Patent: August 18, 2020Assignee: Petroleum Analyzer Company, LPInventors: Michael Brosseau, Thomas Herold, Simon Blass, Oezkan Oguz

Publication number: 20160313292Abstract: In the production of petroleum-based products in a refinery, viscosity and density are accurately and repeatedly measured at an elevated temperature, sometimes in a hostile environment. A densitometer and viscometer are located in a non-purged enclosure, but the electrical controls that could cause a spark to ignite fumes are located in a purged enclosure with connections there between. A heat pipe extending from the purged enclosure to the non-purged enclosure accurately controls the temperature of a sample during testing. For difficult to handle petroleum-based products such as asphalt, a sample conditioning system prepares the sample prior to testing.Type: ApplicationFiled: March 4, 2016Publication date: October 27, 2016Applicant: Petroleum Analyzer Company, LPInventors: Chetan Desai, Patrick Dalbello, David Anthony Malaguti, Jonathan Stephen Lilley, Daniel Airey

Patent number: 8444314Abstract: A thermal oxidation tester is shown for determining thermal stability of a fluid, particularly hydrocarbons when subjected to elevated temperatures. The tendency of the heated fluid to oxidize and (1) form deposits on a surface of a heater tube and (2) form solids therein, are both measured at a given flow rate, temperature and time. The measured results are used to determine whether a fluid sample passes or fails the test. Results of the measurements are recorded. The fluid under test is pumped with a low volume, high pressure, single piston pump with only a small fluctuation (pulsation) in output flow.Type: GrantFiled: December 2, 2010Date of Patent: May 21, 2013Assignee: Petroleum Analyzer Company, LPInventors: Larry M. Youngblood, David G. Anderson, Guoxing Yang

The tendency of the heated fluid to oxidize and (1) form deposits on a surface of a heater tube and (2) form solids therein, are both measured at a given flow rate, temperature and time. The measured results are used to determine whether a fluid sample passes or fails the test. At the beginning of each test, the test sample is aerated with dry air until saturation. Simultaneously, the test equipment is primed to remove pockets of air there from. After each test, the test equipment is flushed to remove the test sample there from.Type: GrantFiled: September 17, 2010Date of Patent: October 23, 2012Assignee: Petroleum Analyzer Company, LPInventors: David G.

Drop counter and flow meter for apparatus and method for determining the thermal stability of fluids
Patent number: 8277118Abstract: A thermal oxidation tester is shown for determining thermal stability of a fluid, particularly hydrocarbons when subjected to elevated temperatures. The tendency of the heated fluid to oxidize and (1) form deposits on a surface of a heater tube and (2) form solids therein, are both measured at a given flow rate, temperature and time. The measured results are used to determine whether a fluid sample passes or fails the test. Sample flow rate is important in the jet fuel thermal oxidation test. Current practice requires manual drop counting or flow confirmation with the use of volumetric glassware. An apparatus is described to precisely measure the flow rate and automatically perform flow rate check using a drip rate method and/or volumetric method.Type: GrantFiled: August 4, 2010Date of Patent: October 2, 2012Assignee: Petroleum Analyzer Company, LPInventors: David G.

Patent number: 8246244Abstract: A thermal oxidation tester is shown for determining thermal stability of a fluid, particularly hydrocarbons, when subjected to elevated temperatures. The tendency of the heated fluid to oxidize and (1) form deposits on a surface of a heater tube and (2) form solids therein which are both measured at a given flow rate, temperature and time. The measured results are used to determine whether a fluid sample passes or fails the test. Specifically constructed containers used in a thermal oxidation tester are shown. These containers (1) reduce physical contact to hydrocarbon test fuels, (2) reduce exposure to hydrocarbon fuel vapors, (3) reduce environmental impact by reducing chemical spills, and (4) improve overall work flow of test.Type: GrantFiled: August 23, 2010Date of Patent: August 21, 2012Assignee: Petroleum Analyzer Company LPInventors: Larry M.
