Controlling System Design And Research Of Methyl Alcohol Carbonyl Synthesis Acetic Acid

The acetic acid is one kind of important chemical product, mainly uses in producing the acetic acid ethylene,the acetate,the acetyl cellulose,the acetic anhydride and the dicarboxylic acid and so on the important chemical product, also has the widespread use in professions and so on spinning and weaving.Along with our country national economy development, the acetic acid increases year by year in the domestic consumption quantity.Estimated the next several year acetic acid the demand will still maintain8～10%rate of increment,The methyl alcohol carbonyl synthesis legal system acetic acid craft is our country maintains independence and keeps initiative to study develops and invests the application one kind of technology. This article introduced the methyl alcohol carbonyl synthesis legal system acetic acid technical process and the overall control request, introduced the measuring appliance shaping principle of design, the reactor’s temperature controlling and the interlock opening and shutting down, as well as rectifying tower control and so on, Introduced the online analysis system design, as well as DCS system and ESD system disposition and software configuration and so on.At present the Jiangsu Sopo600kt/year acetic acid three issue of project already smoothly operated,the movement condition is stable,the product quality,the output had achieved the design target,reducing the production cost, creating the good economic efficiency.
