Abstract: In the bottom blown process for the refining of molten steel, additional heat is generated for melting greater amounts of scrap, by injecting at least one secondary stream of an oxygen-containing gas to the space above the molten metal bath so as to combust the CO and H 2  evolving therefrom. The excess heat so generated is absorbed both by the bath and the furnace lining, causing overheating and rapid deterioration of the lining. For a given quantum of heat so generated the ability of the molten metal to absorb a greater portion of that heat and thereby maintain the temperature of the furnace lining within the practical limits has been found to depend to a significant extent on the design of the furnace itself. The invention is directed to conducting the refining process in vessels which provide, for a given bath capacity, greater top surface areas than has heretofore been employed.

Abstract: A process for treating H 2 S-containing gases which have also a relatively high CO 2  content, wherein sulphur-containing compounds of said gases are converted to elemental sulphur in a Claus plant. The process is applied to gases having a calculated H 2 S/CO 2  ratio of less than 1. 
     In a first absorption zone (2a, 2b) sulphur-containing compounds (H 2 S, COS, CS 2 ) and C0 2  are absorbed in a liquid under non-selective absorption conditions, and after regeneration of said absorption liquid, partly fed to a Claus plan (10) and partly to a catalytic reduction zone (17). 
     The off-gas of the Claus plant is also introduced in said reduction zone wherein any sulphur compounds other than H 2 S are converted into H 2 S in the presence of H 2  and/or CO. The gas mixture leaving the reduction zone is treated for H 2 S removal in a second absorption zone (20) with the same liquid as applied in said first zone under conditions which are selective in respect of co-absorption of CO 2 . The H 2 S-containing absorption liquid of said second zone is regenerated in a regeneration zone (7) common to the first and second absorption zone, whereby the calculated H 2 S/CO 2  ratio of the feed to the Claus plant is improved.
