METHOD OF REMOVING NITROGEN OXIDES FROM CHIMNEY GAS |
摘要 |
FIELD: gas purification. ^ SUBSTANCE: method comprises treating the flow of chimney gas in the high-temperature zone with a temperature of 700-1200°C by means of gas reducing mixture that is preliminary is produced by thermal decomposition of solid carbamide out of the zone for treating the gas and is supplied to the zone of purification by the gas-carrier. The carbamide is decomposed by rising its temperature from 100 to 600°C. The rate of the temperature rise is 5-40°C/min and 35-40°C/min for the temperature range from 100 to 400°C and temperature higher than 400°C, respectively. ^ EFFECT: simplified method. ^ 3 cl, 1 dwg, 1 tbl |
