Abstract
The present invention provides a system and process for olefin polymerization. The inventive system and process for olefin polymerization facilitate lower operating vacuum pressures in the polymer recovery system by requiring at least two sequential condensing units, wherein at least one of the condensing units operates at significantly lower temperature ranges than the temperature ranges at which the current systems operate.
