    摘要： A test coupon is formed from a metallic strip having opposite first and second sides that generally define a plane of the strip and the strip includes a laser shock peened patch of the strip that has first and second laser shock peened surfaces on the first and second sides, respectively, first and second laser shocked regions having deep compressive residual stresses imparted by the laser shock peening extending into the strip from the first and second laser shock peened surfaces, respectively, and a deflection of a portion of the strip from a position of the portion before the laser shock peening. The deflection is formed by the laser shock peening such that at least a part and preferably substantially all of the deflection lies in the plane and the test coupon preferably includes an indicating means to indicate the deflection.

    摘要： A method for quality assurance of a laser process and more particularly a laser shock peening process that uses a test coupon having a deflection formed by a laser firing. The test coupon is from a metallic strip having opposite first and second sides that generally define a plane of the strip and the strip includes a laser shock peened patch of the strip that has first and second laser shock peened surfaces on the first and second sides, respectively, first and second laser shocked regions having deep compressive residual stresses imparted by the laser shock peening extending into the strip from the first and second laser shock peened surfaces, respectively, and a deflection of a portion of the strip from a position of the portion before the laser shock peening. The deflection is formed by the laser shock peening such that at least a part and preferably substantially all of the deflection lies in the plane of the strip and the test coupon preferably includes an indicating means to indicate the deflection. The quality assurance process of the present invention may further include correlating high cycle fatigue to the deflection.

    摘要： The invention is a method of inhibiting the formation of fouling deposits occurring on the surface of an alkaline scrubber used to remove acid gases, such as hydrogen sulfide, carbon dioxide and mercaptans, from hydrocarbon streams. These deposits are formed during the scrubbing of pyrolytically produced hydrocarbons contaminated with oxygen-containing compounds with a caustic solution having a pH>7 which comprises adding an effective deposit-inhibiting amount of a non-enolizable carbonyl compound to the caustic solution. The invention is also a method of inhibiting the formation of fouling deposits occurring in spent caustic wash/stripper systems used for hydrocarbon manufacturing processes. Fouling occurs in these systems when they are in contact with hydrocarbon processing streams contaminated with oxygen-containing compounds, such as aldehydes. These deposits are formed in hydrocarbon processing streams contaminated with oxygen-containing compounds while in contact with a caustic solution having a pH>7. The invention comprises adding an effective deposit-inhibiting amount of a non-enolizable carbonyl compound to the caustic solution. Preferred non-enolizable carbonyl compounds are formaldehyde, glyoxal, benzaldehyde, p-anisaldehyde, formic acid, glyoxalic acid and paraformaldehyde.

    摘要： A method for the determination of organic hydroperoxides in a hydrocarbon which has been subjected to oxidative polymerization conditions is disclosed. The steps employed in the invention include mixing an organic cupric salt such as cupric acetate and a phenanthroline such as 2,9-dimethyl-1,10-phenanthroline with a sample of the hydrocarbon in an organic solvent such as acetonitrile, measuring the color change after a fixed period of time for cuprous complex formation, and comparing the measurement to the color change of a standard reference to determine the relative quantity of organic hydroperoxide in the sample.
