Abstract

Un proceso para producir soluciones acuosas de poliacrilamida mediante polimerización de una solución acuosa que comprende al menos acrilamida, para obtener un gel acuoso de poliacrilamida, y mediante disolución de dicho gel acuoso de poliacrilamida en agua, en donde las etapas de elaboración se distribuyen en dos ubicaciones diferentes A y B, y el proceso comprende la etapa de transportar un gel acuoso de poliacrilamida mantenido en una unidad de polimerización transportable de una ubicación A a una ubicación B. La unidad de polimerización transportable comprende una parte superior cilíndrica, una parte cónica en su extremo inferior, alimentaciones para la solución acuosa de monómero, una abertura inferior que se puede cerrar, y medios que permiten implementar la unidad de polimerización de manera vertical.
