METHOD AND DEVICE FOR CONTROLLING STATIC CHARGE IN POLYOLEFIN REACTORS Russian patent published in 2012 - IPC C08F10/00 C08F2/34 

FIELD: process engineering.

SUBSTANCE: invention relates controlling the beddings in gas phase reactor with fluidised bed. Proposed comprises producing polyolefin using metallocene catalyst and static charge regulator in gas phase reactor; measuring static charge level in gas phase reactor using first static charge pickup; measuring the loss static charge level in has phase reactor using second pickup of static charge; and feeding static charge regulator into gas phase reactor in amount sufficient for maintaining measured level of static charge loss and measured static charge level in layer at positive magnitude. Note here that amount of static charge regular fed into gas phase reactor is based on measure static charge loss level and layer static charge level.

EFFECT: regulation and minimisation of bedding on walls and dome of gas phase reactor.
