| Abstract: | Aiming at no dust collection section in the original design of urea prilling tower a technical transformation is carried out to the prilling tower with a dust-collection technology of 3-stage absorption/3-stage separation and the ammonia content in the collected off-gas from the prilling tower drops to below 30 mg/m3 from 80 mg/m3 and the dust content in urea to below 50~90 mg/m3 from 500~600 mg/m3. |
