Abstract:
A study of intervention solutions for the exhaust from 4 thermo-electrical kilns, from synthetic process of in NH3 and dust due to NPK fertilizer production was carried out to evaluate the efficacy of technological improvement solutions in reducing environment pollution. Results: concentration of dust and toxic fumes was reduced, concentration of the exhaust components eliminated to environment through the chimneys of gases-made kilns reduced significantly after changing technology. NH3, CH4, H2 from producing NH3 decreased clearly, dust from producing NPK reduced 1.63-1.92 times
