: Oxygen Stripping Column
: BASF Dow HPPO
Short Name: Oxygen Stripper
Description: The Off-Gas Stream from the Lights Removal Column is compressed (16 atm) with cooling (35 °C) and fed to a Stripping Column under pressure, to obtain an Olefin-containing Bottom Stream (potentially also containing Propane) recycled to the Epoxidation, and an Off-Gas Stream with a low Hydrocarbon content, containing Nitrogen, Oxygen and further volatile By-Products.
