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.

Abstract: RESUMEN La presente invención se refiere a un método para producir una solución de poliacrilamida que tiene mayor viscosidad. En particular, la presente invención se refiere a la separación de un biocatalizador de una solución acuosa de acrilamida que se prepara utilizando el biocatalizador antes de la polimerización de la solución acuosa de acrilamida para obtener poliacrilamida. Una solución de poliacrilamida que tiene viscosidad aumentada es adecuada para el uso en la recuperación terciaria de petróleo. Consecuentemente, la presente solicitud proporciona medios y métodos para mejorar significativamente la calidad de soluciones de poliacrilamida para el uso en la recuperación terciaria de petróleo.
