Dryer (32)
Description

The cooled lean phase (43) is combined with fresh feed of solvent and monomer (30) to provide the desired concentrations and then passed through a
drier (32) which serves to remove any unreacted water used as the catalyst killer or present in the fresh feed supplied or any impurity in the recycled solvent and
monomer as will be explained.

The vapor from vessel (26) is routed to the reflux drum (39) of tower (36). Partly it is processed to recover valuable components, principally volatile monomers such as ethylene and propylene, by fractionating tower (36) and its overhead vapor compression/condensation system for recycling through conduit (43) to the inlet side of the drier (32).
