【摘要】 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。更多还原

【Abstract】 Oil distillation is very important in petrifaction production.Its production level plays an important role in oil using-rate and economic benefit of a corporation.At present,DCS is very popular in oil distillation process.But a FCS is designed for an oil distil- lation unit in a petrifaction factory to meet the request of market competition and increase economic benefit.The reason of choosing FCS is presented;the system framework is given and the design method of FCS is particularly stated.After using FCS,the economic benefit of this factory is increased and the safety operation is assured.更多还原
