China's cis-1,4-polybutadiene rubber (BR) production plants adopt solution polymerization process with hexane as solvent.At present,the unit solvent consumption lies in a general high level.On the base of solvent routing and balance-analysis,solvent loss mainly happens in three aspects such as end gas,residual liquid discharge and oil tank dewatering.By selecting the advanced three-kettle coagulation technology,renovating the paddle in coagulation tower,upgrading the dehydration device in the wet solvent tank,reducing the polymerization formula and optimizing the residual emission operation,the unit solvent consumption can be controlled at 28 kg per tons of BR,which is China's advanced level. © 2020, China National Chemical Information Center.
