OPERATION BOTTLENECK ANALYSIS OF BUTADIENE PLANT AND PREVENTIVE MEASURES
By taking statistics of butadiene plant oper-ation problems and analyzing the rules that cause the problems,it is found that the main problem of butadi-ene plant operation is butadiene polymerization.Polym-erization causes are further analyzed and are discovered to be mainly the effects of oxygen,temperature,buta-diene concentration,and impurities and the effect of initiators such as rust and water.By adopting anti-po-lymerization measures for equipment and process,op-timization of anti-polymerization agent,reducing dead space of equipment and other production anti-polymer-ization measures,the butadiene plant has been running steadily for 4 years without being cleaned instead of the previous annual clean-up.This has helped the compa-ny to achieve better economic benefits,which is worth summarizing and promoting.
