Notes:
The absorption of dilute SO2 into aqueous double slurries containing CaCO3 and Mg(OH)2 was carried out using a stirred tank with a plane gas-liquid interface. The absorption rate increased and finally reached that under the completely gas-film controlled conditions as the absorption process proceeded. The desulfurization process using the double slurry was formulated by a two-reaction-plane model in which there are no particles suspended in-between the interface and the primary reaction plane. It was suggested from comparison of the experimental absorption rates with the theoretical predictions that 40 to 60% of the absorbed sulfur dioxide may be present as an effective magnesium sulfite ion pair.
