  • Patent number: 10221368
    Abstract: The present invention is directed to a formulation of corrosion inhibitors for corrosion control of low carbon steel piping, carrying different fuels products, obtained in refineries or petrochemical processes. The composition comprises active imidazoline inhibitors derived from vegetable oil selected from the group consisting of sunflower, canola, soybean, safflower, corn and mixtures thereof that are reacted with a polyalkylated polyamines such as diethylenetriamines (DETA), triethylenetetramine (TETA) and tetraethylenepentamine (TEPA). The imidazoline is reacted with 1 to 3 moles of a carboxylic acid having 2 to 6 carbon atoms. The product obtained is formulated with 50 to 60% weight of an aromatic solvent and 10 to 20 wt % of an alcohol.
    Type: Grant

  • Patent number: 6083473
    Abstract: A catalyst for selective oxidation of sulfur-containing compounds comprising a metal of Group VIIIA which forms an active metal oxide supported on a support comprising a laminar phyllosilicate, alone, or in combination with silica or alumina. Laminar phyllosilicate and silica impregnated with a metal of Group VIIIA which forms an active metal oxide that achieves a conversion in excess of 95 percent of hydrogen sulfide or acid gas selectively to elemental sulfur and water, respectively.
