Butadiene self-polymer is very easy to appear in the production process of butadiene,and self-polymers are easy to cause spontaneous combustion,bursting valves and pipelines,explosions,etc.Excessive self-polymerization will also cause equipment bursting,prompting medium leakage,cau-sing serious accidents such as fire and explosion.Oxygen content and temperature are the main condi-tions for the formation of butadiene polymers.The focus of selection is to reduce the influence of oxy-gen content and temperature on the self-polymer.Selecting a valve with a purge valve,by injecting an inhibitor and ensuring the dose,the oxygen content in the valve and the generation of self-polymers can be effectively controlled.The research shows that understanding the formation mechanism of butadi-ene self-polymer and reasonable valve selection can effectively control and reduce the formation of polymer,and provide a strong guarantee for the stability,long periodicity and safety of butadiene extrac-tion unit.
