A process of partial oxidation is performed in a reactor which includes a reaction chamber and a burner assembly, wherein: the burner assembly has a single oxidant nozzle located within an fuel channel, said oxidant nozzle comprises a nozzle pipe and a nozzle outlet, the nozzle pipe and the fuel channel are arranged to produce a diffusion flame, the nozzle outlet has a shape with two or more elongate lobes projecting from a center of the nozzle pipe.

Reactor and process for partial oxidation

A process comprising: subjecting a process gas containing NOx to a stage for absorption of NOx in a suitable absorption means, obtaining nitric acid and a tail gas containing nitrogen, argon and residual NOx; subjecting said tail gas to a treatment which comprises at least one NOx removal stage, obtaining a conditioned tail gas; subjecting at least a portion of said conditioned tail gas to a separation treatment, obtaining a product stream containing argon and a product stream containing nitrogen.
