A method of safely mixing a hydrocarbon with an oxidant is provided. The hydrocarbon and oxidant are saturated with a non-flammable liquid in pre-mix zones that are flooded with the non-flammable liquid and fluidly connected to a common mixing zone that is partially flooded with the non-flammable liquid. The saturated hydrocarbon and oxidant combine within the common mixing zone forming bubbles of a homogeneous gas mixture of hydrocarbon and oxidant, preferably in a ratio of hydrocarbon to oxidant that is outside of the flammability limit, that can exit the non-flammable liquid into a headspace where it can be retrieved for use in an oxidative reaction process such as oxidative dehydrogenation.

The present disclosure relates to limiting the production of acetic acid in an oxidative dehydrogenation process to convert ethane to ethylene. The process of oxidative dehydrogenation includes feeding acetic acid, along with ethane and oxygen into an oxidative dehydrogenation reactor where contact with a catalyst leads to conversion of the ethane into ethylene and acetic acid. By including acetic acid in the feed, the amount of acetic acid produced may be limited and the ratio of ethylene produced to ethane consumed may increase.
