Patent ID: 11242413

Abstract:
A method for the control of a plant (10) for the production in continuous of a polymer, wherein the plant (10) comprises at least one reactor (11) fed with at least a first monomer and a second monomer, a first stripper (12), a second stripper (17), a third stripper (18), at least one recycling vat (13) of the fine products, measurement equipment (14) and a control system comprising distributed control devices (15) controllable by at least one electronic processing and control unit (16) based on a plurality of control variables, the control method comprising the following steps: collecting data comprising recipe parameters, laboratory analysis results and predefined coefficients stored in a database (40); collecting the data measured by the measurement equipment (14); determining, by means of a first calculation module (20) a production potentiality value of the at least one reactor (11); determining, by means of a second calculation module (21) the polymer concentration in the at least one reactor (11), in the first stripper (12) and in the at least one recycling vat of the fine products (13); determining, by means of a third calculation module (22) the flow-rate of oil for feeding the second stripper (17); determining, by means of a fourth calculation module (23), the flow-rate of the chain terminator (TERM) for feeding the at least one reactor (11), controlling the plant (10) on the basis of the plurality of control variables.
