ANALYSIS OF AMMONIA (NH3) EMISSIONS TREATMENT IN FACTORY PRODUCTION I PT. PETROKIMIA GRESIK

Abstract

Ammonia (NH3) occurs naturally in low concentrations in areas that are not polluted. At higher concentrations would poison aquatic organisms present in a large scale. Toxicity of unionized ammonia will be higher if the low temperature and high pH.Ammonia concentration above 0.11 mg /L would pose a risk of growth disturbance in all species of marine fish, marine plants for the concentration of ammonia at 25 micromoles per liter causes of death (I.Riwayati 2010 case: 27-32). The purpose of this study is to describe the quality of emissions of ammonia (NH3) in the exhaust stack emissions of ammonia (NH3) in the factory unit I PT. PetrokimiaGresik , and to describe the effectivityofammonia emissions treatment in unit Factory I PT. Petrokimia Gresik. The variable of study is quality of ammonia emissions and the effectivity of ammonia emission treatment. This study was descriptive, using the method of observation. The result showed that the concentration of NH3 per month is still below the quality standard of the Environment. Their emissions scrubber system, especially in the processing of NH3 gas in Urea Plant to reduce concentrations of NH3 are released in the air, so that the ambient air quality is maintained and does not cause negative effects to health and the environment in residential PT. PetrokimiaGresik.
