Abstract

The invention discloses a control method and system for the petrochemical industry to solve the problem that due to the fact that parameters are controlled through manual operation in an existing control method and system, the control is not accurate, and the resource allocation is not optimized enough. The control method includes the steps of firstly, collecting or receiving production parameters of machining of an oil refinery in a given period of time; secondly, under the constraint conditions that the primary machining corresponding to a feed and crude distillation device and the secondary machining, refined oil product blending and delivery corresponding to a second machining device are simulated, solving the production parameters through a linear or non-linear optimization, and thereby generating control parameters; thirdly, generating control instructions according to the control parameters; fourthly, controlling production procedures of the machining of the oil refinery according to the control instructions. The control method has the advantages of being rapid in response, accurate in control and the like, the resource allocation of raw materials and devices is facilitated, therefore, production cost is reduced, and production efficiency is improved.

Description

technical field [0001] The invention relates to the field of petrochemical technology, in particular to a control method and system for the petrochemical industry. Background technique [0002] The control parameters used by refineries and chemical plants to control petrochemical processing are derived manually based on actual production parameters. Manual derivation strongly depends on the experience, business level and work status of the designated staff. Moreover, petrochemical production involves many types of raw materials and complicated processing steps. Manual analysis and calculation are often not only insufficient in calculation accuracy and precision, but also unable to obtain optimal control parameters, often resulting in low processing efficiency, waste of raw materials, and backlog or lack of inventory. Both lead to problems such as increased production costs. Contents of the invention [0003] (1) Technical problems to be solved [0004] The technical pro...
