Abstract |
The report gives the results of a study of the reactions of calcium hydroxide, calcium carbonate, and limestone with the aqueous (sodium, sulfite, bisulfite, and sulfate) system. Concentrations and stoichiometries typical of those for sodium-based double-alkali scrubbing systems were used. The reactions were studied in a stirred, nitrogen-purged glass reaction vessel immersed in a constant-temperature bath. The objectives were to study various reactions of importance in the sodium-based double-alkali process and to define possible operating modes for the process. Results indicate desirable operating ranges and may be used to support engineering design of pilot-scale double-alkali scrubber systems. Appendices include experimental data, references, and theoretical discussions. (Author) |
