Fertilizers

Fertilizer plants handle extensive processes—crushing, mixing, granulation, drying, blending, and packaging—that generate high concentrations of dust and potentially harmful gases like ammonia (NH₃), sulfur oxides (SOx), and nitrogen oxides (NOx). Modern filtration systems are essential to protect worker health, prevent abrasive damage to machinery, reduce product loss, and ensure compliance with stringent global emission limits.

Primary systems include pulse-jet baghouse filters to capture particulate emissions; cyclone separators for coarse pre-cleaning; and dry or wet scrubbers to neutralize corrosive and odorous gases. In some installations, activated carbon beds are added downstream to control VOCs and trace ammonia. When compared to competitors, leading systems offer modular upgrades that integrate these technologies seamlessly with digital controls.

Both wet and dry scrubber systems neutralize acid gases and ammonia by CO₂ absorption and chemical reaction. Wet scrubbers use alkaline solutions to transform SOx or NH₃ into neutral salts, while dry scrubbers inject powdered reagents to avoid generating wastewater. Competitor solutions often combine scrubbers with downstream bag filters to handle scrubber-generated particulates, delivering full compliance, even under strict discharge standards.
