Emission capture and treatment in fertilizer plants
Extensive experience in capturing gaseous emissions and dust in plants manufacturing SSP (single superphosphate), TSP (triple superphosphate), DAP (diammonium phosphate), MAP (monoammonium phosphate), NPK fertilizers and urea.
Gaseous emissions and dust: the challenge of the fertilizer industry
Fertilizer manufacturing plants generate emissions with high concentrations of particulates, corrosive gases and fluorine compounds that must be captured and treated effectively.
Extreme process conditions
Fertilizer manufacturing generates complex emissions combining corrosive gases (HF, NH₃), fluorine compounds (SiF₄) and a high content of particulates and dust. These conditions require specialised equipment, designed to withstand the abrasion, corrosion and high temperatures typical of these processes.
- Capture of emissions with a high content of particulates and dust
- Removal of HF and SiF₄ in superphosphate plants
- NH₃ and HF scrubbing in DAP, MAP and urea production
- Treatment of dust and NH₃ at high temperatures in NPK plants
- Equipment resistant to abrasion and chemical corrosion
- Compliance with environmental emission regulations
Technologies tailored to each fertilizer type
Our offering includes gas treatment technologies using venturis, cyclones, multi-venturis and scrubbing towers, adapted to the demanding conditions of these applications.
Each type of fertilizer plant has a different emission profile: superphosphate plants generate HF and SiF₄, ammoniated fertilizer plants release dust, NH₃ and HF, and NPK plants produce dust and NH₃ at high temperatures. TECNIUM selects and sizes the optimal equipment for each specific application.
Three application areas in fertilizer plants
TECNIUM provides specific gas scrubbing solutions for each type of fertilizer manufacturing process.
Gas scrubbing in superphosphate plants
Application for scrubbing air contaminated with a series of gases that also have a significant particulate and dust content. The equipment used in this case consists of venturi-cyclones in series, designed to remove HF, SiF₄ and F₂.

Gas scrubbing in ammoniated fertilizers
Scrubbing of air contaminated with a series of gases together with a high content of particulates and dust. The equipment used is a combination of a venturi-cyclone system followed by one or two stages of chemical scrubbing towers, removing the dust, NH₃ and HF generated during the production of DAP, MAP and urea.

Common questions about gas treatment in fertilizer plants
TECNIUM applies its chemical absorption technology (TECNIUM-CHEM) for the treatment of emissions in fertilizer plants. This technology includes high-efficiency venturis, cyclones, combined venturi-cyclones, multi-venturis for high temperatures and single- and multi-stage chemical scrubbing towers. The selection and combination of equipment is adapted to the type of plant (SSP, TSP, DAP, MAP, NPK or urea) and the specific pollutants of each process.
In superphosphate plants (SSP and TSP), gaseous emissions are generated with a high content of hydrofluoric acid (HF), silicon tetrafluoride (SiF₄) and fluorine (F₂), in addition to particulates and dust. TECNIUM uses venturi-cyclones in series to efficiently capture and remove these fluorine compounds.
In ammoniated fertilizer plants (DAP, MAP and urea), emissions contain dust, ammonia (NH₃) and hydrofluoric acid (HF). TECNIUM uses a combination of a venturi-cyclone system followed by one or two stages of chemical scrubbing towers to remove these pollutants. This multi-stage configuration enables the plant to meet regulatory emission limits.
Complex NPK fertilizer plants generate emissions with a high content of particulates and ammonia (NH₃) at high temperatures. For these extreme conditions, TECNIUM uses multi-venturis specially designed to withstand the high temperatures and to capture both dust and NH₃ efficiently during the granulation process.
Fertilizer manufacturing processes involve handling highly corrosive fluids such as phosphoric acid, sulphuric acid, ammoniated solutions and hydrofluoric acid. Conventional metallic pumps and fans cannot withstand these conditions. TECNIUM manufactures pumps and fans in plastic materials (PP, PVC, PVDF, E-CTFE, FRP) that ensure complete corrosion resistance and long service life.
Yes. TECNIUM has more than 70 years of experience and references across the five continents.
