Claim 1
Independent Claim
135 words
A METHOD OF REMOVING WATER-SOLUBLE CHLORINE COMPOUNDS FROM GASES OBTAINED BY COMBUSTION OF WASTE LIQUORS FROM THE PULPING OF CELLULOSIC MATERIALS BY THE SULFITE OR SULFATE PULPING METHODS, WHICH COMPRISES CONTACTING SUPERHEATED GASES RESULTING FROM SAID COMBUSTION AT A TEMPERATURE WITHIN THE RANGE FROM ABOUT 100 TO ABOUT 400*C., AND AT A VELOCITY WITHIN THE RANGE FROM ABOUT 10 TO ABOUT 20 METERS PER SECOND WITH COLD WATER AT A TEMPERATURE WITHIN THE RANGE FROM ABOUT 0 TO ABOUT 20* C., AND AT AN AVERAGE DROPLET SIZE WITHIN THE RANGE FROM ABOUT 0.1 TO ABOUT 0.5 MM. IN AN AMOUNT SUFFICIENTLY IN EXCESS OF THE AMOUNT REQUIRED TO SATURATE THE GAS TO LOWER THE TEMPERATURE OF THE GAS TO ABOUT 0.2 TO ABOUT 2*C. BELOW THE DEW POINT OF THE GAS SATURATED WITH WATER VAPOR.
