Problems solved by technology

In the prior art, when designing the matching ethylene glycol regeneration and recovery system, generally only the process mechanism model is used for calculation design, the design accuracy is low, and the actual equipment and process still rely on the experience of technicians to a large extent, lacking intuition, simplicity, The easy-to-use process simulation system is used to guide the design and use, and cannot effectively support the process verification of enterprise users in the actual process. End users still need to conduct a large number of test production in the actual chemical reaction device to adjust and optimize process conditions and control parameters. , so that the generation efficiency of ethylene glycol regeneration is low, the cost is high, and it will bring certain safety risks at the same time

Abstract

The invention relates to an automatic simulation method for an ethylene glycol regeneration and recovery system. According to the method, an intelligent agent module is set to achieve the real-time input, control and result feedback of an ethylene glycol regeneration and recovery process; particularly, a plurality of intelligent agent modules can be mutually connected and networked to form a distributed control network to realize standardized transmission between data, so that full-dimensional simulation of the ethylene glycol regeneration and recovery process and an automatic control system thereof is realized; and in combination with a digital twin platform, a user can discuss and analyze different control schemes and process conditions to the maximum degree of freedom, so that time is saved, and a large amount of funds and operation cost are also saved.

Description

technical field [0001] The invention relates to the technical field of chemical process industry, in particular to an ethylene glycol regeneration recovery process simulation system and method. Background technique [0002] During the development of offshore deep-water gas fields, in order to improve resource utilization and reduce environmental impact, it is necessary to use an ethylene glycol regeneration recovery system, which will involve, for example, a pretreatment system, a three-stage electrodialysis system, and a double-effect recovery rectification tower system. In the prior art, when designing the matching ethylene glycol regeneration and recovery system, generally only the process mechanism model is used for calculation design, the design accuracy is low, and the actual equipment and process still rely on the experience of technicians to a large extent, lacking intuition, simplicity, The easy-to-use process simulation system is used to guide the design and use, a...
