The problem of self-polymerization in monomer storage tanks
Thread Content

Please analyze this situation: neither the high-boiling nor low-boiling towers in our facility have experienced serious self-polymerization problems, whereas self-polymerization occurs quite severely in the monomer storage tank. It should be noted that our polymer recycling and production systems are separate. # ， ， &
Could you be more specific? Such as self-assembly position, self-assembly period.
It may be self-polymerization resulting from equipment corrosion caused by the water in the storage tank not being drained in time.
Especially at the bottom of the storage tank, self-polymerization is most severe
It is recommended to recycle VCM along with inhibitors; a rod-type alkali dryer should be designed for the monomer, and the technology provided free of charge by Shanghai Chlor-Alkali can be utilized, with Shanghai Chlor-Alkali supplying the products
Increase the number of drainage cycles per monomer tank! Use less inhibitor unless there are special circumstances
Temperature, water content, and other factors all have an impact
The recycled monomer is on the acidic side; the storage tank may be corroded
It is likely due to excessive water content, coupled with severe issues at the bottom; this is probably the reason, and drainage needs to be improved. Measures that can be taken: add water removal equipment after the high and low towers, before the monomer tank.
