Brink® Mist Eliminators for Ammonium Nitrate Prill Towers


Designing fiber bed mist eliminator systems for AN prill towers requires an acute knowledge of salt formation and the effects they have on the efficiency and operation of the system and plant. With tightening regulation governing particulate emissions at the stack, mist eliminators must balance emissions control with pressure drop, service life and capital costs in order to fulfil their target requirements.

Brink® Mist Eliminators for AN Prill Towers


To wash the AN salts and control their formation on and in the fiber beds, an irrigation system is a must. However, particle size distribution in ammonium nitrate solids presents mist eliminators with a challenge. Impaction devices are frequently unable to remove submicron-sized mist produced in upset conditions. To get around this issue, we have designed and successfully deployed irrigation systems that use spray-wetted mesh pads for pre-filtration and humidification. Additional element throat sprays are also used for effective fiber bed irrigation and wash down. This AN prill “scrubber” arrangement has resulted in very high efficiency, zero opacity and long fiber bed life. The heart of this AN prill tower “scrubber” system is the Brink® Fiber Bed Mist Eliminator, which employs three special design features for AN service.
• Polyester and/or high-temperature polymeric fiber for long life.
• Rigorous quality-controlled angle wrap roving fiber or bulk pack for customized performance and pressure drop characteristics.
• Bi-component fiber beds for fast drainage of captured mist and irrigation artifacts for highest efficiency.
