Problems solved by technology

The control parameters used by the traditional monitoring system to generate control instructions are manually formulated based on experience, resulting in the accuracy, precision and feasibility of the formulated control parameters strongly relying on the experience and business level of the designated personnel
In addition, in the existing monitoring system, it usually only receives control parameters, generates control instructions, and controls the operation of processing equipment, without verifying the feasibility of control parameters when used to control production, so as to control the accuracy and / or precision of parameters The fluctuation of the degree will lead to low overall production efficiency, equipment and human resources will not be optimized, resulting in high processing costs and other issues

Abstract

The invention discloses a monitoring method and system for production in the petrochemical industry. The method comprises the steps that the monitoring system collects production parameters of petrochemical production within schedule time; under the constraint conditions of simulation feeding, primary processing corresponding to a crude distillation device, secondary processing corresponding to a secondary processing device, refined oil product blending and shipment, linear or nonlinear optimization is adopted to solve the production parameters, and therefore control parameters are generated; under the constraint conditions of the processing devices simulating petrochemical production, a storage container, the connection relation between the processing devices, and the connection relation between the processing devices and the storage container, feasibility verification is carried out on the control parameters according to the production parameters, the next step is carried out if the verification result is feasible, and if the verification result is not feasible, parameters restricting feasibility of the control parameters are regulated according to the verification result, and after the regulated control parameters are obtained, the previous step is carried out; a control command is formed according to the control parameters; petrochemical production is controlled according to the control command.

Description

technical field [0001] The invention relates to the field of petrochemical technology, in particular to a monitoring method and system for production in the petrochemical industry. Background technique [0002] Refining and chemical plants are used to control the final formation of instructions, which need to comprehensively consider factors such as actual production parameters, laboratory data, inventory, and shipments. The control parameters used by traditional monitoring systems to generate control instructions are manually formulated based on experience, resulting in the accuracy, precision, and feasibility of the formulated control parameters strongly relying on the experience and professional level of the designated personnel. In addition, in the existing monitoring system, it usually only receives control parameters, generates control instructions, and controls the operation of processing equipment, without verifying the feasibility of control parameters when used to ...
