Abstract
Oxidative dehydrogenation is an alternative to the energy extensive steam cracking process presently used for the production of olefins from paraffins. Various embodiments of an oxidative dehydrogenation chemical complex designed to allow removal of sulfur containing contaminants that collect in the gas mixer unit and in the feed lines leading to the ODH reactor are disclosed herein.
Claims13
A chemical complex for the oxidative dehydrogenation of lower alkanes, the chemical complex comprising in cooperative arrangement:
- i) at least two mixers for premixing an oxygen containing gas and a lower alkane containing gas to produce a mixed feedstock stream and additionally comprising a cleaning loop;
- and
- ii) at least one oxidative dehydrogenation reactor;
- wherein the at least two mixers are connected in parallel to the at least one oxidative dehydrogenation reactor so that either a first gas mixing unit or a second gas mixing unit is connected to the at least one oxidative dehydrogenation reactor during normal operations;
- and
- wherein an oxidative dehydrogenation catalyst contained within the at least one oxidative dehydrogenation reactor reacts with the mixed feed stock stream to produce a product stream comprising the corresponding alkene.
