Nitrogen Fertilisers

Filter › Platinum Catalyst Dust

NITRIC ACID / PLATINUM CATALYST OR PALLADIUM DUST RECOVERY

NH3 is oxidised with air on catalyst to form NO at high temperature (700 – 1000 °C ), in a quick exothermic reaction. After cooling, NO is oxidised by excess air to give NO2. This oxidation continues into the...

Nitrogen Fertilisers

Gas Cleaning › Ammonium Nitrate Granulator Dryer

NITROGEN FERTILISERS / AMMONIUM NITRATE – GRANULATOR DRYER

Ammonium Nitrate (NH4NO3) is granulated then dried as a final process stage.
The drying process emits both Ammonium Nitrate dust and Ammonia at appx. 50 °C :
Typical Inlet dust load: 15,000 to 20,000 mg/Nm3 Ammonium Nitrate prills
Typical Inlet...

Nitrogen Fertilisers

Gas Cleaning › Urea Granulator

NITROGEN FERTILISERS / UREA GRANULATOR SCRUBBER

Urea solution is granulated then dried as a final process stage. There are various process providers, such as Toyo and Uhde, some of which involve fluidised bed technology.
The process emits both Urea dust and Ammonia:
Typical Inlet Urea dust load...

Phosphate Fertilisers

Filter › Cross Flow Scrubbers

PHOSPHATE FERTILIZER PRODUCTION – PHOSPHORIC ACID / FUME SCRUBBERS

Depending on the process technology and the source of the emission, the nature of the emissions (content quantity and type of contaminant) determines the best design of scrubber in each case.  HF, H2FiS6 (FSA), P2O5 and NH3 are the...

Phosphate Fertilisers

Filter › Air Scrubber Exit Vanes

PHOSPHORIC ACID / SCRUBBER EXIT DROPLET SEPARATORS

Most Air Scrubbers treating gas emissions to atmosphere in Phosphoric Fertiliser plants (MAP, DAP, NPK etc) have a Chevron Vane type or a mesh type droplet separator on the exit to catch liquid droplets.
These Chevron Vanes and mesh pads can block, and need replacing from...

Phosphate Fertilisers

Gas Cleaning › P2O5 Wagon Loading – Fugitive Emissions

PHOSPHORIC ACID / WAGON LOADING – FUGITIVE EMISSIONS CONTROL

Product Loading Stations transfer Phosphorous to (railway) wagons, and this generates both P4 dust and P2O5 vapours, which escape into the atmosphere.
Phosphorous and Phosphoric Acid particles come from the air around the product transportation & loading operation...

Phosphate Fertilisers

Process Equipment › Reactor Tank Agitators and Thickeners

PHOSPHATE FERTILISER PRODUCTION – Reactor Tanks

Phosphate rock is processed in reactor tanks for flotation.
Other process reactions are also done in tanks with the aid of agitating equipment.
PROBLEMS TO SOLVE
Improving the efficiency of the reaction / mixing / dispersal / sedimentation by optimising the agitator...

Phosphate Fertilisers

Process Equipment › P2O5 Rotating Table Vacuum Filter

PHOSPHATE FERTILISER PRODUCTION – P2O5 Separation from Phosphate Slurry

Phosphoric Acid is extracted from Phosphate slurry by wash watering it on a rotating table vacuum filter, where the P2O5 content is drawn off by vacuum through the meshes on the table, and through drainage pipes underneath. The residual...
