  • Organo-sulfur compounds as high temperature antifoulants
    Patent number: 4116812
    Abstract: This invention relates to a process of inhibiting or preventing fouling (i.e., preventing the adhesion of deposits from hydrocarbon on surfaces) at elevated temperatures which comprises adding to hydrocarbon an antifouling (preventing) amount of an organo-sulfur compounds having a high sulfur content. In the preferred embodiment, the organo-sulfur compound has at least 5% sulfur. An embodiment is a heterocyclic compound, a dithiole-thione. These organo sulfur compounds are particularly effective at elevated temperatures of at least about 500.degree. F.

    Assignee: Petrolite Corporation
    Inventors: Richard L. Godar, Philip R. Corneli
  • Process of inhibiting corrosion and/or sweetening hydrocarbons
    Patent number: 4029589
    Abstract: A process of inhibiting corrosion and/or sweetening hydrocarbons so that they pass the Copper Strip Tarnish Test ASTM D-130 which comprises treating such hydrocarbons with iodine or bromine. These halogens are preferably employed with complexing compounds such as amines, carboxylic acids, alcohols, alkanolamines, ketones, etc.
