Complete Set Of Process Gas Analysis System In Typical Applications In Petrochemical Industry

Complete set of process gas analysis system is by the sampling device, sample pretreatment device,on-line gas analysis instruments, analyzer instrument to protect equipment and auxiliary facilities, signalprocessing and communications equipment and so on, can be directly installed in the industrialproduction process, to complete the process of medium to be measured the automatic sampling andphysical parameters of qualitative and quantitative analysis, and continuously provide signal output. Asthe national petroleum and chemical industrial equipment, such as large scale and the overall technologyand equipment of ascension, as the country of saving energy and reducing consumption, improve quality,pollution emission reduction and safe production of increasingly pursuit, the importance of the completeset of process gas analysis system and usage is growing.In the past for a long time, however, due to our part of the blind worship of foreign petrochemicalengineering technical staff analyzer instruments and complete sets of system for process gas analyzer donot understand, make a significant portion of the foreign advanced analyzer instruments have goodapplication in domestic engineering, unable to realize advanced analysis instrument of productionprocess control. The research purpose of this research is to combine the practical experience of typicalapplication in the field of petrochemical process gas analyzer of complete system, summarizes theresearch objective to provide some effective solutions. This topic research significance lies in thepromotion of complete system of the localization process gas analyzer, on-line gas analyzer instrumentis more suitable for the analysis of the long-term stability of timely, in order to meet the petroleumchemical industry the need of advanced process control engineering.Paper research method is to refer to relevant technical data at home and abroad, to participate in ther&d and production of complete sets of process gas analysis system, in-depth study of complete sets ofprocess gas analysis system used in the analysis of principle of various analytical instruments, samplepretreatment in the thorough analysis of complete sets of process gas analysis system components andanalysis of the function of the cabin, system research process gas analyzer in oil chemical industry, theapplication of the system of complete, finally put forward the complete set of process gas analysissystem in petrochemical industry of the representative solution.Paper main research content is as follows: the first chapter discusses the this topic researchbackground, research significance, research status at home and abroad and the main research content ofthis topic, the second chapter introduces the definition of the on-line gas analysis instrument,classification, and all kinds of measuring principle of gas analysis instrument, the third chapter presentsthe basic concept and the function for sample pretreatment unit, the fourth chapter analyses the cottage and analyzer system installation, the fifth chapter presents the process analysis for petrochemicalindustry use complete set of system and some typical solutions, the sixth chapter summarizes the workof the paper content, research results and shortcomings.Thesis research is to detect and solve the combined with practical experience in the petrochemicalindustry applications of complete set of process gas analysis system, the current domestic analyticalinstruments used in the operation of the petrochemical industry, there are still many practical problemsto be solved, hope that through this article to the topic, cause the attention of more engineering andtechnical personnel in this aspect, make the complete set of process gas analysis system application inpetrochemical industry can be better, have the effect of direct production.
