Short Name
Surge Tank (26)
Description

The lean phase (20), after being cooled by the heat exchanger (12) is cooled further by a cooling device (24), passed through a surge tank (26)
adapted for stripping out the hydrogen and then submitted to in-line chemical analysis at (43) to determine the concentration of monomer and comonomer in the
solvent.

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).
