| Abstract: | The absorption of ammonia from air by water was studied in a tower with an internal diameter of 75 mm and a 150 mm packed height with 8 mm Raschig rings.The concentration of ammonia in gas was less than 10% (volume).The absorption tomperature and pressure were about 20℃ and 1 atm,respectively.According to experimental data,an empirical formula for the volume transfer coefficient was obtained. |
