  • Emulsion minimizing corrosion inhibitor for naphtah/water systems
    Patent number: 5174957
    Abstract: A corrosion inhibitor formulation for oil and water systems which formulation is resistant to sludge formation and does not tend to stabilize oil/water emulsions when added to oil and water systems. The corrosion inhibitor includes an imidazoline dissolved in an aromatic solvent, a 2-hydroxyalkylcarboxylic acid such as glycolic acid and a glycol such as hexylene glycol. The imidazoline is preferably prepared from a long chain fatty acid and a polyamine in a molar ratio of about 1.5:1.
    Type: Grant
    Filed: January 3, 1992
    Date of Patent: December 29, 1992

  • Method of charge neutralization using chelants
    Patent number: 4992164
    Abstract: A method of neutralizing chloride ions present in a hydrocarbon medium during processing in a petroleum refinery. Nitrilotriacetic acid or its salt form is injected into the crude charge upstream of the preheat unit. Chloride levels are reduced in this way without the deleterious effects which result from treatment with the conventionally used NaOH.
