    Abstract: Disclosed is a concentrated cooling water additive that is substantially non-corrosive within a pH range of 2-12 and contains polymeric dispersant(s) and aromatic azole(s) that exhibits improved stability, possibly as a result of the interaction of the hydrophobic groups in the dispersant polymer and the aromatic azole(s). This improved stability allows for both reduced corrosivity of the formula and reduced manufacturing costs. Benefits of the disclosed formulations include improved safety for handling and shipment, more concentrated formulations available in liquid form, reduced shipping costs and storage space, reduced heat of neutralization during product manufacture, reduced costs of manufacture due to removal of need for caustic or acid addition and reduced environmental compliance costs associated with washing and waste handling step.

  • Publication number: 20120286196
    Abstract: This invention covers a formulation providing protection against corrosion in liquid and vapor phase. Such formulations are used in applications where engine parts or fuel cell systems are subjected to a “running-in” or “hot-test” prior to final assembly or storage. The invention includes a concentrate as well as a dilute solution. The synergistic combination of inorganic ammonium derivatives in combination with monocarboxylic or dicarboxylic acids increases the period of protection. This enables storage for a longer period when the engine parts are shipped or stored prior to assembling. The use of the described invention pre-conditions the metal surface and provides protection even if afterwards the liquid is almost completely removed.

  • Publication number: 20120067782
    Abstract: A method for reducing the amount of hydrogen sulfide present in liquid hydrocarbon media while minimizing the amount of corrosion in processing equipment contacting the liquid hydrocarbon media. The method includes neutralizing a glyoxal solution and dispersing the neutralized glyoxal solution in the liquid hydrocarbon media. The neutralized glyoxal solution is dispersed within the liquid hydrocarbon media not more than 10 days after the glyoxal solution has been neutralized. A hydrogen sulfide scavenging composition and method for making are also provided.
