  • Process for producing a polyacrylamide solution with increased viscosity
    Patent number: 10975177
    Abstract: The present invention relates to a method for producing a polyacrylamide solution having increased viscosity. In particular, the present invention is related to the separation of a biocatalyst from an aqueous acrylamide solution prepared utilizing the biocatalyst prior to polymerization of the aqueous acrylamide solution to polyacrylamide. A polyacrylamide solution having increased viscosity is well suited to be used in tertiary oil recovery. Accordingly, the present application provides means and methods to crucially improve the quality of polyacrylamide solutions for use in tertiary oil recovery.

  • PROCESS FOR PRODUCING A POLYACRYLAMIDE SOLUTION WITH INCREASED VISCOSITY
    Publication number: 20190112399
    Abstract: The present invention relates to a method for producing a polyacrylamide solution having increased viscosity. In particular, the present invention is related to the separation of a biocatalyst from an aqueous acrylamide solution prepared utilizing the biocatalyst prior to polymerization of the aqueous acrylamide solution to polyacrylamide. A polyacrylamide solution having in creased viscosity is well suited to be used in tertiary oil recovery. Accordingly, the present application provides means and methods to crucially improve the quality of polyacrylamide solutions for use in tertiary oil recovery.

  • Method for preparing an aqueous acrylamide solution having a low acrylic acid concentration
    Patent number: 10227621
    Abstract: The present invention relates to methods for preparing an aqueous acrylamide solution having a low acrylic acid concentration. In addition, the present invention relates to methods for reducing the acrylic acid concentration of an aqueous acrylamide solution. The methods involve a bioconversion of acrylonitrile to acrylamide in the presence of a biocatalyst, wherein during the bioconversion the content of acrylonitrile is maintained at 0.3 w/w % or more referred to the total weight of the composition in the reactor. Also provided is an aqueous acrylamide solution which is obtained by the methods of the present invention. Furthermore, the present invention is related to an acrylamide homopolymer or copolymer obtained by polymerizing the acrylamide of the aqueous solution.
