大型煤制乙二醇项目自控设计与应用

Design and Application of Instrument Design for Large-Scale Coal to Ethylene Glycol

在石油、化工、冶金、电力、轻工和建材等工业生产中,生产过程的主要参数有温度、压力、流量、液位、分析等,通过对这些过程参数的自动控制,可使生产过程中产品的产量增加、质量提高、能耗减少和生产效率的提高,同时能保证装置的安全生产和运行。因此,生产过程自动化是保持生产稳定、降低消耗、降低成本、改善劳动条件、促进文明生产、保证生产安全和提高劳动生产率的重要手段,仪表合理设计与应用是保证生产过程自动化的前提,是装置稳定运行的保障。

In those industrial production such as the petroleum, chemical, metallurgy, electric power, light industry and building materials, the main parameters of the production process are temperature, pressure, flow, liquid level, analysis, etc., Through the automatic control of these process parameters to increase production, improve quality, reduce energy consumption and improve production efficiency and guarantee the safety of production and operation. Therefore, production process automation is an important means to maintain production stability, reduce consumption, reduce costs, improve labor conditions, promote civilized production, ensure production safety and improve labor productivity. The reasonable design and application of instrument is not only the premise to guarantee the production process automation, but also the safeguard for the stable operation of the plant.
