FIELD: methods for controlling gas phase polymerization reactors.
SUBSTANCE: method for controlling a fluidized bed reactor includes forming a fluidized bed in the reactor, the fluidized bed including monomers and a catalyst, and obtaining a polymer product. Then the polymer product is unloaded from the reactor into the product discharge tank and the polymer product is unloaded from the product discharge tank into the blow tank. The pressure in the blow tank is measured as the polymer product enters the blow tank and quickly evaporates, and one or more operating parameters of the reactor are changed based on the pressure measured in the blow tank.
EFFECT: provision of control over the reactor and a qualitative assessment of the conditions in the reactor, which increases the productivity of the reactor and the quality of the polymer product.
