  • Method of controlling gas hydrates in fluid systems
    Patent number: 10392573
    Abstract: A method of inhibiting hydrates in a fluid comprising water and gas comprising adding to the fluid an effective hydrate-inhibiting amount of a composition comprising one or more homo- or co-polymers of N-alkyl(alkyl)acrylamide synthesized by polymerizing one or more N-alkyl(alkyl)acrylamide monomers in a solvent comprising a glycol ether of formula CH3—(CH2)m—(O—CH2—CH2)n—OH where m is an integer of 0-1, and n is an integer ?1.
    Type: Grant
    Filed: October 17, 2008
    Date of Patent: August 27, 2019
    Assignee: Ecolab USA Inc.
    Inventors: Joseph R. Carlise, Olga E. S. Lindeman, Peter E. Reed, Peter G. Conrad, Leonard M. Ver Vers
  • Method of controlling gas hydrates in fluid systems
    Patent number: 9550935
