CONFIGURATIONS AND METHODS FOR SOX REMOVAL IN OXYGEN-CONTAINING GASES.

摘要

Sulfur oxides are removed from an oxygen-containing acid gas (102) in configurations and methods in which oxygen is removed from the acid gas using reducing gases at relatively high temperature. The so treated acid gas is then fed to a direct reduction reactor (130) in which the sulfur species are converted to elemental sulfur (132).Contemplated configurations are particularly effective and economically attractive as they are generally not limited by reaction equilibrium as presenting a Claus reaction and do not require solvent and solvent-associated equipment.
