| In china which has a high speed increase of economy,the Information-based and automation being a development trend of chemical engineering business enterprise production. Each business enterprise continuously adopts new technique and new craft to exaltation production efficiency,so as to keep a good profession position in the fierce competition.The distributed control system with its good stability, credibility get the favor of majority business enterprise,How make distributed control system(DCS) in the production exertive it the superior effect become researchers' main research direction. This text did an analysis and optimization design to the application of distributed control system in methyl tertiary butyl ether(MTBE) production.First,it had a elaboration to domestic and international development, circumstance of application, advantage, characteristics of DCS, carried on more detailed of introduction for this equip's craft process, craft request, the equipments constitute and hardware structure to constitute, each parts of function characteristics, function of allocation software etc. of the SUPCON WebField JX-300X DCS of Zheda zhongkong company which this equip adopted combine MTBE actual production of shandong shida shenghuaIncorporated company.Second,this text discussed the craft blemish and control project blemish to produce equip through the analysis of produce craft process and control project to the MTBE equip combine with the feedback information of operator in actual production.Base on that,this text did a craft improvement to the equip and optimization design to the control project.In order to improve automation degree,and lower energy exhaust variable-frequence voltage technique and methanol/isobutene ratio's on line measurement were adopted.This text also discuss the principle, characteristics, superiority which lead into the technique.Third,this text carried on hardware allocation to the control system according to the contents of optimization design,and introduced configurate process to control system( SUPCON WebField JX-300X DCS ) through using configuration software AdvanTrol-Pro.It made the hardware parameter of the system constitution and actual production good match,and good function of DCS such as real time monitoring ,operating,real-time conditioning,analysis, processing function achieved.Currently,science and technique change with each passing day,research of DCS gradually mature.Application of DCS in MTBE production displayed special superiority,the gap reduced compared with international control system .Be in line with nations and exaltation the international competition ability currently are urgent need of each business enterprise. Therefore, the research of DCS application technique has important value. |
