Abstract

Background and Objective: Workplace Air quality is a very important factor in community health, which is measured using Airborne contaminants evaluation and measurement. One of these Airborne pollutants in industries is ammonia gas. Spray Towers are important components of Air pollution control. This study aimed to investigate the effects of dilute Sulfuric Acid Solution on the efficiency of Ammonia Removal in a Spray Tower. Materials and Methods: This study evaluated the rate of Ammonia Removal from the Air stream using a Spray Tower with laboratory criterion by altering the liquid pressure and nozzles, as well as the inlet density. The volume of the used Airstream was 3737. 82 l/min; moreover, one, two, and three 20micron diameter nozzles were used with the dilute Sulfuric Acid Solution. The data were analyzed in SPSS software (version 21) through one-way ANOVA. Results: An increase in the number of nozzles and washing liquid pressure of the Spray Tower increased the Ammonia Removal efficiency and enhanced the input load of the system which reduced the elimination efficiency (P<0. 05). Conclusion: An increase in the number of nozzles, the operating pressure of the washing liquid, and the density of the pollutant gas lead to a higher level of spraying tower efficiency in terms of eliminating the ammonia gas from the Air stream.
