An improved continuous solution polymerization process wherein energy consumption is reduced, comprising: i) injecting ethylene, one or more aliphatic hydrocarbon solvents, a catalyst, optionally one or more α-olefins and optionally hydrogen into at least one upstream reactor operating at a temperature and pressure to produce an ethylene polymer in a single liquid phase solution; ii) injecting a catalyst deactivator, downstream of said upstream reactors, into the single liquid phase solution containing ethylene, solvents, catalyst, ethylene polymer, optional α-olefins and optional hydrogen, to form a deactivated reactor solution; iii) passing the deactivated reactor solution through a heat exchanger to increase the temperature, followed by reducing the pressure, followed by producing a bottom stream of ethylene polymer rich solvents, deactivated catalyst and optional α-olefins and a gaseous overhead stream of ethylene, solvents, oligomers, optional α-olefins, and optional hydrogen in a V/L separator; iv) passing not more than 40% of the gaseous overhead stream to a distillation column; v) passing the remainder of the gaseous overhead stream through a halide removal column, followed by condensing the gaseous overhead stream by reducing the temperature, to form a condensed overhead stream; vi) passing the condensed overhead stream through a means for oligomer removal, producing a cold recycle stream; vii) passing the cold recycle stream through a lights separator to remove volatile components to produce a purged recycle stream; viii) passing the purged recycle stream through at least two purification vessel, producing a purified recycle stream; ix) collecting the purified recycle stream in a recycle drum, passing the purified recycle stream through pump and injecting a high pressure recycle stream into said upstream reactors. i) injecting ethylene, one or more aliphatic hydrocarbon solvents, a catalyst, optionally one or more α-olefins and optionally hydrogen into at least one upstream reactor operating at a temperature and pressure to produce an ethylene polymer in a single liquid phase solution; ii) injecting a catalyst deactivator, downstream of said upstream reactors, into the single liquid phase solution containing ethylene, solvents, catalyst, ethylene polymer, optional α-olefins and optional hydrogen, to form a deactivated reactor solution; iii) passing the deactivated reactor solution through a heat exchanger to increase the temperature, followed by reducing the pressure, followed by producing a bottom stream of ethylene polymer rich solvents, deactivated catalyst and optional α-olefins and a gaseous overhead stream of ethylene, solvents, oligomers, optional α-olefins, and optional hydrogen in a V/L separator; iv) passing not more than 40% of the gaseous overhead stream to a distillation column; v) passing the remainder of the gaseous overhead stream through a halide removal column, followed by condensing the gaseous overhead stream by reducing the temperature, to form a condensed overhead stream; vi) passing the condensed overhead stream through a means for oligomer removal, producing a cold recycle stream; vii) passing the cold recycle stream through a lights separator to remove volatile components to produce a purged recycle stream; viii) passing the purged recycle stream through at least two purification vessel, producing a purified recycle stream; ix) collecting the purified recycle stream in a recycle drum, passing the purified recycle stream through pump and injecting a high pressure recycle stream into said upstream reactors.
