| Summary: | The objective of this work by SRI International was to develop a novel system for regenerable SO₂ and NOₓ scrubbing of flue gas that focuses on (1) a novel method for regenerating spent SO₂ scrubbing liquor and (2) novel chemistry for reversible absorption of NOₓ. High efficiency, hollow fiber contactors (HFCs) were proposed as the devices for scrubbing the SO₂ and NOₓ from the flue gas. The system would be designed to remove more than 95% of the SO₂ and more than 75% of the NOₓ from flue gases typical of pulverized coal-fired power plants at a cost that is at least 20% less than combined wet limestone scrubbing of SOₓ and selective catalytic reduction of NOₓ. In addition, the process would generate only marketable by-products, if any (no waste streams are anticipated). The major cost item in existing technology is capital investment. Therefore, the approach was to reduce the capital cost by using high-efficiency, hollow fiber devices for absorbing and desorbing the SO₂ and NOₓ. The authors also introduced new process chemistry to minimize traditionally well-known problems with SO₂ and NOₓ absorption and desorption. The process and progress in its development are described. |
