Abstract

Oxygen-enhanced combustion in a manufacturing plant using a nitrogen plant to obtain a nitrogen product stream for use in the plant is effected by utilizing the oxygen-rich vent, waste, or exhaust stream as the primary source of oxidant for combustion of fuel in burners used to heat furnaces and the like in the same plant. Processes according to the invention employ a vent stream in place of a high purity oxygen stream for oxy-fuel combustion, oxygen lancing, and oxygen boosting.
