  • Formulations of random polymers for improving crude petroleum flow
    Patent number: 9932430
    Abstract: The present invention is related to the use of formulations of new random copolymers and terpolymers, synthesized by a method of semi continuous emulsion polymerization, and that function as flow improvers, lowering the pour point and reducing the viscosity of Mexicans crude oils, which have gravities within the range of 9 to 30° API.
    Type: Grant
    Filed: December 8, 2014
    Date of Patent: April 3, 2018
    Assignee: Instituto Mexicano Del Petroleo
    Inventors: Laura Veronica Castro Sotelo, Eugenio Alejandro Flores Oropeza, Gabriel Cendejas Santana, Marcelo Lozada Y Cassou, Flavio Salvador Vazquez Moreno
  • Demulsifying and dehydrating formulations for heavy crude oils based on block copolymers bifunctionalized with amines
    Patent number: 9518231
    Abstract: The present invention relates to demulsifying and dehydrating formulations of heavy crude oil based block copolymers amine bifunctionalized with low polydispersities. These formulations can contain solvents whose boiling point is in the range from 35 to 200° C., preferably: dichloromethane, chloroform, toluene, xylenes, turbosine, naphtha or mixtures thereof.
