Abstract
Polymerization process having a plurality of processing steps in which an inert gas is used or is provided as a back-up, each of the processing steps being assigned a ranking based on the requirement for an inert gas flow in the processing step. The process, in the event of a process upset, controls with a control system the supply of available inert gas based on the rankings.
