| titleOfInvention | PROCESS FOR THE PRODUCTION OF MAGNESIUM BISULPHITE COOKING ACID FROM THE SMOKE GASES PRODUCED BY THE COMBUSTION OF MAGNESIUM BISULPHITE THICK LIQUID |
| abstract | Process for mfg. magnesium bisulphite digestion acid by heating thick magnesium bisulphite lye to evolve gases which, after wet-filtration by a water-curtain, travel through amulti-stage SO2 absorption plant which is also fed with the clarified slurry obtd. from the filter water and the ash washed out during wet-filtration. After wet-filtration and before entering the absorption plant, the gases are cooled to the temp. of the first absorption stage by injecting water into the gases, and part of the injected water and the condensate thus obtd. is used for the wet-filtration stage, whereas the remainder of the injected water is cooled and re-injected, i.e. a circulating system is used. The technique is useful e.g. in the digestion of wood to form pulp, the SO2 being reclaimed in this process. |
