Abstract

Un sistema y método para descargar una suspensión de transferencia desde un primer reactor de polimerización a través de un conducto de transferencia hacia un segundo reactor de polimerización, la cual suspensión de transferencia incluye al menos diluyente y un primer polietileno. Una suspensión de producto se descarga del segundo reactor de polimerización, la cual suspensión de producto incluye al menos diluyente, el primer polietileno y un segundo polietileno. Se determina la velocidad, la caída de presión o la pérdida de presión debido a la fricción en el conducto de transferencia y se ajusta una variable de proceso en respuesta a la velocidad, la caída o la pérdida de presión que no cumple con un valor específico.
