Achieving 99% NH3 Emission Reduction in Fertilizer Manufacturing

Initial Operation and System Trials

A fertilizer manufacturing company wanted to eliminate NH3 emissions originating from its chemical storage.

In 2022, this fertilizer manufacturer contacted Aager to reduce its productionrelated emission levels to meet current standards, aiming to minimize environmental damage, ensure employee health, and comply with national legal obligations. Following measurements and engineering studies conducted with the company, it was calculated that a 15,000 m3 storage tank would emit 5270 ppm of NH3 due to climatic effects and operational uses.

Eco-Friendly Fertilizer Production: Overcoming NH3 Emission Challenges

Studies and Proposed Solution

Computer simulations and laboratory studies suggested the installation of two 2-stage Wet Pack Scrubbers and one chemical reactor to treat the chemicals and reclaim the emitted emissions for the fertilizer producer. This approach aimed to eliminate emissions discharged into the atmosphere and recycle the waste back into the company’s processes.

Implementation

After the process emissions analysis, the designed units were installed. Upon system activation, a cyclically operating chemical storage tank was monitored monthly for three months by an accredited emission measurement company, ensuring continuous compliance with the guaranteed emission values.
