Abstract

Systems and process for wet and combinations of wet and dry removal of targeted pollutants, such as oxides of sulfur, oxides of nitrogen, and oxides of carbon from combustion and other industrial process gases and processes utilizing the system. Oxides of manganese are utilized as the primary sorbent in the system for removal or capture of pollutants. In wet removal, oxides of manganese are mixed in a slurry which is introduced into reaction zones of the system. In dry removal, the oxides of manganese are introduced from feeders into reaction zones of the system where they are contacted with a gas from which pollutants are to be removed. Removal may occur in single-stage, dual-stage, or multi-stage systems with at least one of the reaction zones being a wet scrubber. A variety dry scrubber may be utilized in combination wet and dry removal systems. Process parameters, particularly system differential pressure, are controlled by electronic controls to maintain minimal system differential pressure, and to monitor and adjust pollutant removal efficiencies. Reacted sorbent may be removed from the reaction action zones for recycling or recycled or regenerated with useful and marketable by-products beins recovered during regeneration.
