  • 3-hydroxypropionic acid compositions
    Patent number: 9512057
    Abstract: Methods and systems for producing high purity 3-hydroxypropionic acid (3-HP) from an aqueous medium, such as a fermentation broth, are described. Aqueous 3-HP solution can be purified by flash evaporation wherein the 3-HP is vaporized at an elevated temperature without conversion to acrylic acid. This process can be integrated with downstream processes for producing other chemical and consumer products.
    Type: Grant
    Filed: March 14, 2014
    Date of Patent: December 6, 2016
    Assignees: Cargill, Incorporated, Dow Global Technologies LLC
    Inventors: Cindy Hoppe, Sarah M. Hoyt, Robert Tengler, David DeCoster, Bradley Harkrader, Patrick H. Au-Yeung, Sanjib Biswas, Pedro R. Vargas, II, Raymond P. Roach, Timothy Charles Frank

  • PURIFICATION OF 3-HYDROXYPROPIONIC ACID FROM CRUDE CELL BROTH AND PRODUCTION OF ACRYLAMIDE
    Publication number: 20140309451
    Abstract: A process for producing high purity 3-hydroxypropionic acid from a fermentation cell broth is described. The 3-hydroxypropionic acid can be converted to a variety of products, such as acrylamide, 3-hydroxypropionic esters, acrylic esters, and 3-HP amide. This process features a high degree of product flexibility, limited or no solvent recycle, discrete waste streams, an efficient water removal process, and efficient recovery of products and solvents with proven and scalable equipment.
