Abstract
El uso de evaporación por película descendente y un montaje de concentración tal como separación centrífuga para deshidratar y concentrar una emulsión o suspensión de polímero de agua-en-aceite se describen. En una modalidad preferida, una composición de polímero de agua-en-aceite contiene menos de aproximadamente 25 de sólidos de polímero activo, se deshidrata en evaporador de película descendente para producir un concentrado de evaporador que contiene menos de aproximadamente 5.0 de agua. El concentrado de evaporador luego circula a un aparato de separación tal como una centrífuga, en donde se retira el aceite para producir una composición que es substancialmente una composición de surfactante-en-aceite emulsificante y polímero que contiene exceso aproximadamente 60 en peso de sólidos de polímero. El refinado de centrífuga opcionalmente puede tratarse en un segundo montaje de separación para capturar sólidos de polímero adicionales con reciclado opcional del refinado rico en aceite. La composición de polímero concentrado, de preferencia se estabiliza con un estabilizante estérico para producir un producto líquido de flujo libre.
