ABSORPTION OF NOx IN SODA SOLUTION IN AN ACTIVATED CARBON PACKED TOWER
活性炭填料塔碱吸收NOx尾气的研究

The absorption of NOx on towers packed with activated carbon and porcelain Rasching rings of same macro-surface area were compared. The results showed that the absorption efficiency and overall absorption coefficient of the activated carbon tower were 10% and 60-70% higher than those of the porcelain Rasching rings packed one under same space velocity. The optimal conditions for a divided-flow process using soda solution in an activated carbon packed tower were suggested under which the 89-97% of absorption efficiency and reduction of NOX concentration in exhaust from 4000-5000ppm to 157-455ppm could be reached.
