Abstract
The present invention is a method for disposal of noxious waste products generated in petroleum refining including spent caustic solution and concentrated sulfur effluent from treating of petroleum fractions to remove sulfur therefrom. Essentially the spent caustic solution and the concentrated sulfur effluent is incinerated in the presence of air in order to form the oxides of sulfur which react with the incinerated caustic to form alkali metal sulfides.
