Abstract
The sulphur-containing gas emissions from a sulphate cellulose pulp mill are minimized by combusting malodorous gases produced by the pulp mill, and by minimizing the use of chemicals which can disrupt the sulphur/sodium balance of the pulp mill. Sulphurous malodorous gases are combined with soap and/or black liquor to produce a fluid, which is burned in a cylindrical water cooled reaction vessel to produce a melt containing sodium sulphate and sodium carbonate. Chemicals are recovered from the melt by dissolving it in liquid in a dissolving tank to produce a melt solution, combining the melt solution with weak black liquor, and burning the combination in a soda recovery boiler. The flue gases produced during combustion of the sulphurous gases and soap may be cooled and scrubbed, or may be fed to a waste heat recovery boiler and is burned with bark or sludge.
