Available in PDF, EPUB and Kindle. Book excerpt: The objective of this work is to develop a novel system for regenerable S0[sub 2] and NO. scrubbing of flue gas that focuses on (a) a novel method for regeneration of spent S0[sub 2] scrubbing liquor and (b) novel chemistry for reversible absorption of NO[sub x]. In addition, high efficiency hollow fiber contactors (HFC) are proposed as die devices for scrubbing the S0[sub 2] and NO[sub x] from the flue gas. The system will be designed to remove more than 95% of the SO[sub x] and more than 75% of the NO[sub x] 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 SO[sub x] and selective catalytic reduction of NO[sub x]. In addition, the process will make only marketable byproducts, if any (no waste streams). The major cost item in existing technology is capital investment therefore, our approach is to reduce the capital cost by using high efficiency hollow fiber devices for absorbing and desorbing the SO[sub 2] and NO[sub x]. We will also introduce new process chemistry to minimize traditionally well-known problems with SO[sub 2] and NO[sub x] absorption and desorption. For example, we will extract the SO[sub 2] from the aqueous scrubbing liquor into an oligomer of dimethylaniline to avoid the problem of organic liquid losses in the regeneration of the organic liquid. Our novel chemistry for scrubbing NO[sub x] will consist of water soluble phthalocyanine compounds invented by SRI and also of polymeric forms of Fe[sup ++] complexes similar to traditional NO[sub x] scrubbing media described in the open literature. Our past work with the phthalocyanine compounds, used as sensors for NO and NO[sub 2] in flue gases, shows that these compounds bind NO and NO[sub 2] reversibly and with no interference from O[sub 2], CO[sub 2], SO[sub 2], or other components of flue gas.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: The objective of this work is to develop a novel system for regenerable SO2 and NO(subscript x) 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 NO(subscript x). In addition, high efficiency hollow fiber contactors (HFC) are proposed as the devices for scrubbing the SO2 and NO(subscript x) from the flue gas. The system will be designed to remove more than 95% of the SO2 and more than 75% of the NO(subscript x) 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 SO(subscript x) and selective catalytic reduction of NO(subscript x). The process will generate only marketable by-products. Our approach is to reduce the capital cost by using high-efficiency hollow fiber devices for absorbing and desorbing the SO2 and NO(subscript x). We will also introduce new process chemistry to minimize traditionally well-known problems with SO2 and NO(subscript x) absorption and desorption. Our novel chemistry for scrubbing NO(subscript x) will consist of water-soluble phthalocyanine compounds invented by SRI as well as polymeric forms of Fe{sup ++} complexes similar to traditional NO(subscript x) scrubbing media. The final novelty of our approach is the arrangement of the absorbers in cassette (stackable) form so that the NO(subscript x) absorber can be on top of the SO(subscript x) absorber. This arrangement is possible only because of the high efficiency of the hollow fiber scrubbing devices, as indicated by our preliminary laboratory data. This arrangement makes it possible for the SO2 and NO(subscript x) scrubbing chambers to be separate without incurring the large ducting and gas pressure drop costs necessary if a second conventional absorber vessel were used. Because we have separate scrubbers, we will have separate liquor loops and simplify the chemical complexity of simultaneous SO2/NO(subscript x) scrubbing.

This book was released on 1994 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the third quarter of 1993, we continued work on Tasks 2, 3, 4, 5, and 6. In Task 2, we tested the NO(subscript x) sorption capacity of Fe(II)-EDTA and five new SRI-synthesized compounds. We also made a comparison of all the tests so far and have selected two compounds as the leading candidates. In Task 3, we electrochemically converted FE(III) phthalocyanine to its Fe(II) analog and synthesized several metal phthalocyanine compounds. In Task 4, we evaluated 200-fiber HFC modules for SO2 removal with water and solutions of Na2SO3. We also connected this HFC unit to the liquor regenerating HFC unit described in Task 6. We continue to observe 95--100% SO2 removal. In Task 5, we calculated the overall mass transfer coefficients of earlier Fe(II)-EDTA runs for scrubbing NO(subscript x). We also obtained a new module from Hoechst-Celanese and began its characterization. In Task 6, we demonstrated that the spent liquor from Task 4 can be regenerated using a second HFC. The spent liquor was regenerating using DMA with initial recovery of SO2 up to 52%.

In addition, the process will make only marketable byproducts, if any (no waste streams). During the third quarter of 1995, we continued work on Task 8, integrated NO(subscript x) life tests. We also obtained some mass transfer data on Task 9, performance of scalable modules. In Task 8, we gathered additional 400 hours of NO(subscript x) absorption/desorption data. We also presented the data on NO(subscript x) absorption/desorption behavior over cumulative time to date. the performance indicates unchanged reversible characteristics of Co(II) phthalocyanine solution. Therefore, we believe that NO(subscript x) absorption/desorption chemistry is robust. In Task 9, we experimentally observed the channeling of liquid flow due to poor design of previous rectangular modules. Newly obtained welded rectangular modules out-performed previous modules. We also presented SO2 absorption data using different Na2SO3 concentrations. The SO2 absorption seem to be dependent on liquid flow rate, a rather surprising result compared to earlier results. Apparatus for combined absorption/desorption of SO2 in rectangular modules is also given in this report.

We also began work on Task 7. In Task 2, we incorporated 4.5% O[sub 2] into our simulated flue gas stream during this quarter's NO[sub x]-absorption experiments. We also ran experiments using Cobalt (II)-phthalocyanine as an absorbing agent We observed higher absorption capacities when using this solution with the simulated flue gas containing O[sub 2]. In Task 3, we synthesized a few EDTA polymer analogs. We also began scaled up synthesis of Co(II)-phthalocyanine for use in Task 5. In Task 4, we performed experiments for measuring distribution coefficients (m[sub i]) Of SO[sub 2] between aqueous and organic phases. This was done using the liquor regenerating apparatus described in Task 6. In Task 5, we began working with Co(II)-phthalocyanine in the 301 fiber hollow fiber contactor. We also calculated mass transfer coefficients (K[sub olm]) for these runs, and we observed that the gas side resistance dominates mass transfer. In Task 6, in the liquor regeneration apparatus, we observed 90% recovery of SO[sub 2] by DMA from water used as the scrubbing solution. We also calculated the distribution of coefficients (m[sub i]). In Task 7, we established and began implementing a methodology for completing this task.
