Abstract
A process flow sequence for the reduction of polymer fouling while maintaining efficient production levels wherein a dual pressure, dual column configuration is used to effect the reduction in polymer fouling. The dual pressure, dual column configuration of the invention uses a high pressure and a separate low pressure to isolate the desired fractions while effecting a reduction in the production of fouling polymers.
