Advanced separation technology for flue gas cleanup. Quarterly Technical Report No. 3, January 1993
In the fourth quarter of 1992, we continued work on Tasks 2, 3, and 4. In Task 2, we continued preparation of the reversible absorption apparatus for measuring SO{sub 2} and NO{sub x} solubilities. We received and installed the gas cabinet necessary for safe handling of these gases and made several modifications to the reversible absorption apparatus aimed at reducing the time required for each measurement. We also began evaluating chromatography columns for their ability to separate SO{sub 2}, N{sub 2}, and O{sub 2}. In Task 3, we synthesized three polymers of dimethylangline (DMA). The first, an oligomer of DMA, resulted in an insoluble (to most solvents) solid that is unsuitable for use as an absorbent. In order to produce a liquid material, we synthesized several DMA copolymers. A 50:50 (mole ratio) copolymer of N-phenylaziridine and propyleneimine also resulted in a solid; however, reducing the N-phenylaziridine to propyleneimine ratio to 30:70 produced a liquid at room temperature. Fourteen grams of the 30:70 copolymer were, prepared for absorption measurements. In Task 4, we performed three sets of BFC experiments. The objective of the first two sets was to determine the liquid phase mass transfer coefficient and the objective of the third set was to determine SO{sub 2} removal efficiencies. The Hoechst/Celanese (H/C) BFC modules were not received until late December, limiting us to prototype modules. SO{sub 2} removal efficiencies were greater than 96% even with the prototype modules.
