  • Absorption of Carbon Dioxide at High Temperature with Molten Alkali Carbonate Using Bubble Column Reactor

    Yugo Kanai, Koichi Terasaka, Satoko Fujioka, Kenichirou Fukunaga

    Journal of Chemical Engineering of Japan (The Society of Chemical Engineers, Japan)  52 ( 1 ) 31 - 40 2019

    Research paper (scientific journal), Joint Work, Accepted,  ISSN  00219592

     View Summary

    © 2019 The Society of Chemical Engineers, Japan The purpose of this study is to examine the possibility of establishing a novel CO 2 absorption process with molten alkali carbonate using a bubble column reactor. In our previous study, a hot CO 2 recovery process using Li 4 SiO 4 suspended in molten Li 2 CO 3 -K 2 CO 3 was developed. In the process, molten alkali carbonate itself showed great potential for CO 2 absorption at high temperature. If a hot CO 2 absorption process were established using only molten alkali carbonate, it could make the system simpler and the operating temperature range could be extended without the limitation of reaction temperature of solid absorbent. In the study, molten Li 2 CO 3 , Na 2 CO 3 , K 2 CO 3 and its eutectic mixture were selected as CO 2 absorbent. A bubble column was chosen as the device for gas absorption at high temperature. First, the CO 2 absorption performance of each single molten alkali carbonate was investigated. The result showed that the molten Li 2 CO 3 had a great ability to absorb CO 2 at high temperature. Li 2 O was thought to be produced by decomposition of Li 2 CO 3 during the melting and purging process and a reaction of CO 2 with Li 2 O occurred during the absorption process. Further, the CO 2 absorption performance of eutectic mixture increased exponentially with increasing the ratio of Li 2 CO 3 in composition. Second, the possibility of establishing a CO 2 absorption process using molten Li 2 CO 3 was examined. The overall CO 2 absorption process in the bubble column was investigated and the experimental results showed that the mass transfer of CO 2 into molten Li 2 CO 3 was the rate-controlling step. The operational conditions of the bubble column were optimized. The superficial gas velocity was an important operational parameter that affected both the CO 2 absorption rate and total amount of CO 2 finally absorbed in the bubble column. The operating temperature also greatly affected the amount of absorbed CO 2 .

  • Synthesis, kinetic study, and reaction mechanism of Li4SiO4 with CO2 in a slurry bubble column reactor

     View Summary

    © 2019, © 2019 Taylor & Francis Group, LLC. This study was performed to investigate the synthesis, kinetic and reaction mechanism of Li 4 SiO 4 with CO 2 in a slurry bubble column reactor. The Li 4 SiO 4 powder sample was prepared via a solid-state reaction. The sample was characterized via X-ray diffraction (XRD) analysis and verified as a single phase. The median diameter of the sample was measured using the laser diffraction and scattering method as about 20 μm. The synthesized sample was suspended in binary molten carbonate of Li 2 CO 3 –K 2 CO 3 having a molar ratio of 38:62. The experimental results show that Li 4 SiO 4 in the slurry bubble column absorbed approximately a stoichiometric amount of CO 2 . The kinetic study shows that the CO 2 reaction behavior on the Li 4 SiO 4 surface was fitted to a double exponential model and the limiting step of the reaction was lithium diffusion. The mass transfer coefficient of CO 2 and rate constant of reaction with Li 4 SiO 4 were studied to understand the overall absorption mechanism in the reactor. The resistance for the direct reaction of CO 2 on the Li 4 SiO 4 was much smaller than the resistance for the mass transfer of CO 2 to the Li 4 SiO 4 . We can conclude that the direct contact of CO 2 with Li 4 SiO 4 was the main path for the reaction.

  • Mass transfer from freely rising microbubbles in aqueous solutions of surfactant or salt

    Tanaka S., Kastens S., Fujioka S., Schlüter M., Terasaka K.

    Chemical Engineering Journal (Chemical Engineering Journal)   2019

    ISSN  13858947

     View Summary

    © 2019 Elsevier B.V. Microbubbles are used in many applications. One of the major advantages of using microbubbles is to improve the mass transfer of gases to the bulk phase. In this study, mass transfer from single microbubbles that rise in ultrapure water and aqueous solutions of surfactants (SDS, Pluronic F68) or salt (NaCl) was investigated. The rising and dissolution behaviors of single air microbubbles were observed using a high-speed imaging technique by which the rising velocity, U B , and the mass transfer coefficient, k L , were optically evaluated. We found that the rising velocity of microbubbles obeys Stokes’ law, indicating that the surface of the microbubbles used in this study is immobile, despite their rising in ultrapure water. The obtained mass transfer coefficients were in good agreement with those predicted by Ranz and Marshall's correlation for the Sherwood number, Sh. Using the two correlations for U B and Sh, a theoretical model that describes the mass transfer from a microbubble was constructed. The proposed model can predict the dissolution of single microbubbles rising in ultrapure water and aqueous solutions with an accuracy of ±10% in terms of dissolution time.
