- The objective of this work is to develop a novel system for regenerable SO₂ and NOₓ scrubbing of flue gas that focuses on (a) a novel method for regeneration of spent SO₂ scrubbing liquor and (b) novel chemistry for reversible absorption of NOₓ. In addition, high efficiency hollow fiber contactors (HFC) are proposed as the devices for scrubbing the SO₂ and NOₓ from the flue gas. The system will be designed to remove more than 95% of the SOₓ 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 will make only marketable byproducts, if any (no waste streams). Work will be conducted in a 60-month period (5/92 to 4/97), encompassing 16 tasks. In Task 8, (Integrated NOₓ life tests), the authors have presented the modified experimental arrangement for testing the efficacy of Co(II)-phthalocyanine solution for NOₓ absorption as well as desorption over extended periods of time. This arrangement allows them to automatically acquire data and control process parameters. They obtained absorption/desorption data over a period of 140 hours. The data exhibits average NO removal rates of 50%. In order to increase the overall efficiency of the system, they have designed and built a new desorption section with increased mass transfer area. In Task 9, (scalable modules), the authors presented the design details of the rectangular scalable modules. Also, they tested the apparatus with SO₂/water system. The performance of the device was affected by varying either gas or water flow rates. SO₂ removal rates close to 90% were obtained at 20 SLPM gas flow rates.
