The Cyclohexanone Production Process Safety Monitoring Module Based On KECA

Analysis on the safety monitoring of chemical process on the basis of chemicalengineering, Graduate chemical engineering safety monitoring knowledge learning to thecourse, based on multivariate statistical process monitoring and safety monitoring of oxygenenriched oxidation of cyclohexane in the process of success and failure experience. Study onthe cyclohexanone production process safety monitoring module based on KECA.Production of chemical production processes often require the use of some extremeconditions such as high temperature and high pressure, low temperature vacuum, etc., and theraw materials and products often explosive, poisonous and corrosive characteristics. Modernchemical production processes coupled with the presentation of large-scale, continuous,centralized and other characteristics, such as in the chemical park a larger number of majorhazards, can easily lead to a "domino effect" after the event of an accident, proneQunsiqunshang accident. Once the chemical process accidents caused by normal operationsranging from being destroyed, while in critical human life, and will bring seriousenvironmental pollution, causing huge economic losses. Production process is complexchemical process, DCS collected data is very complex, interrelated between variables and datanonlinear characteristics, which result in chemical process safety monitoring process becomescomplicated.In this paper, these characteristics, enriched with cyclohexane oxidation process, forexample, its different conditions using data generated by the production process analysis andstudy, plus calculation software module implements an algorithm based KECA chemicalprocess monitoring. Actual chemical production process test results showed abnormal situationsuch as this module quickly and accurately detect the process, failure detection rate above98%.
