| 520 | |a"In two previous reports (1, 2), a process was outlined for the recovery of sodium sulphite solution from waste sulphite pulping liquors. The reports also contained a detailed study of the kinetics of the solid state carbonation of sodium sulphide smelts. The study indicated that the state of hydration of the sodium sulphide smelts had a substantial effect on their rate of carbonation. In particular, sodium sulphide monohydrate was found to undergo carbonation much faster than either the higher hydrates or anhydrous sodium sulphide. It was necessary, therefore, to characterize the conditions of temperature and water vapour partial pressure under which the various hydrates and the anhydrous form of sodium sulphide were formed"--Introduction, page 1. |
