1-20. (canceled)
A process for the separation of a hydrocarbon-containing feed stream comprising olefin monomer, co-monomer and hydrocarbon diluent, comprising:
- passing said feed stream to a distillation column;
- subjecting said feed stream to distillation conditions whereby
- a bottom stream comprising substantially olefin-free hydrocarbon diluent is removed;
- a side stream comprising hydrocarbon diluent is removed;
- and
- an overhead vapor stream comprising olefin monomer, hydrocarbon diluent and further components selected from H2, N2, O2, CO, CO2 and combinations thereof and formaldehyde is removed;
- and
- feeding at least a part of said bottom stream to said side stream.

A distillation system comprising:
- a distillation column which is configured to separate a hydrocarbon-containing feed stream comprising olefin monomer, co-monomer and hydrocarbon diluent into a bottom stream comprising substantially olefin-free hydrocarbon diluent, a side stream comprising hydrocarbon diluent and an overhead vapor stream comprising olefin monomer, diluent and further components selected from H2, N2, O2, CO, CO2 and combinations thereof and formaldehyde, wherein said distillation system comprises:
- a feeding line for feeding said feed stream to said distillation column;
- a removal device for removing said bottom stream from said distillation column, a bottom stream storage vessel operably connected to said removal device for storing removed bottom stream, and a removal line operably connected to said bottom stream storage vessel for removing bottom stream from said bottom stream storage vessel;
- a removal device for removing said side stream from said distillation column, a side stream storage vessel operably connected to said removal device for storing removed side stream, and a removal line operably connected to said side stream storage vessel for removing side stream from said side stream storage vessel;
- a removal device for removing said overhead vapor stream from said distillation column;
- and
- a connecting line connecting said removal line with said side stream storage vessel.
