Abstract

The invention discloses a system and process for removing heavies from diluent recycled to a slurry polymerization reactor, the system and process comprise a flash gas separator (18) that receives a slurry (52) comprising liquid medium and solid polymer particles. The flash gas separator (18) separates the diluent from the solid polymer particles as a vapor stream comprising at least diluent and heavies. A line receives the vapor stream (56) from the flash gas separator. The line leads to a heavies removal system (20) that yields a liquid that is relatively concentrated in heavies and a diluent vapor that is relatively free of heavies. The liquid is passed to a heavies column (32), while the diluent vapor is passed to a diluent recycle chamber (30) and then recycled to a slurry polymerization reactor (10) without additional treatment to remove heavies.
