  • CO.sub.2 treatment to remove +2 ionic metal from crude
    Patent number: 6093311
    Abstract: The present invention is a process to remove a +2 ionic charged metal from a petroleum feed. The process includes contacting feed with carbon dioxide at a temperature between 40.degree. C. and 200.degree. C. and autogenous pressure. In a preferred embodiment the metal is a Group II metal. In particular, the metal is calcium.

  • Removal of +2 ion charged metal dissolved in a petroleum feed
    Patent number: 5976358
    Abstract: The present invention is a process to remove a +2 ionic charged metal from a petroleum feed. The process includes contacting the feed with a resin that includes carboxyl, sulfonic and/or phosphonic groups. In a preferred embodiment the metal is a Group II metal. In particular, the metal is calcium.
    Type: Grant
    Filed: March 6, 1998
    Date of Patent: November 2, 1999

  • Process for neutralization of petroleum acids
    Patent number: 5683626
    Abstract: The invention relates to a process for treating naphthenic acid--containing whole crudes or fractions thereof to reduce or eliminate their acidity by contacting the acidic whole crude or fraction at a temperature of from about 50.degree. C. to 350.degree. C. with a neutralizing amount of tetraalkylammonium hydroxide, preferably tetramethyl-ammonium hydroxide. The process has the additional benefits of reducing materials handling problems associated with treating oils using liquid solvents and in reducing emulsion formation.
