PROCESS AND SYSTEM FOR REMOVING HEAVIES FROM DILUENT RECYCLED TO A SLURRY POLYMERIZATION REACTOR |
摘要 |
A recycling and recovery system and process comprising a flash gas separator (18) that receives a slurry comprising liquid medium and solid polymer particles (52). 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 fr ee 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.
