原油蒸馏是石化生产中的重要生产环节,它的生产水平直接影响到整个企业对原油的使用效率和经济效益。目前,在原油蒸馏过程中,多采用集散控制系统(distributed control system,DCS)。但为适应国内外市场竞争要求,提高经济效益,本文针对新疆某石化厂原油蒸馏装置设计了一套现场总线控制系统(fieldbus control system,FCS)。阐述了选择FCS的原因,给出了系统结构图,并详细说明了FCS的设计方案。采用了这套FCS后,显著提高了该厂的经济效益并保证了装置的安全平稳运行。
Crude oil distillation is an important production link in petrochemical production. Its production level has a direct impact on the efficiency and economic benefits of crude oil used by the entire enterprise. At present, in the process of crude oil distillation, distributed control system (DCS) is often used. However, in order to meet the requirements of domestic and international market competition and improve economic efficiency, this paper designs a fieldbus control system (FCS) for a crude oil distillation unit of a petrochemical plant in Xinjiang. The reason of selecting FCS is expounded, the system structure is given, and the design scheme of FCS is described in detail. With this FCS, the economic benefits of the plant are significantly improved and the safe and stable operation of the plant is ensured.
