## Equipment Lozzar Process Supplies to Fertiliser and Agrochemical

| Equipment | Fertiliser Application |
|---|---|
| Rotary Dryer | NPK granules, SSP, TSP, ammonium nitrate, organo-mineral granules |
| Fluidized Bed Dryer | Ammonium sulphate, potassium chloride, urea (cooling + drying) |
| Crystallizer | Ammonium sulphate (from caprolactam or coke oven), SOP |
| Evaporator | Solution concentration: ammonium sulphate, potassium nitrate |
| Cyclone Separator | Pre-separator in granule dryer circuits |
| Bag Filter | PM emission control for dryer, granulator, cooler |
| Wet Scrubber | NH₃ scrubbing (H₂SO₄ scrubber), HF from SSP/TSP lines |
| Belt Conveyor | Granule transport dryer → cooler → screener → storage |
| Heat Exchanger | Air cooling, flue gas heat recovery |

## Key Process Lines

### NPK Granule Drying and Cooling
Granulator discharge (NPK, 3–5 % moisture, 2–5 mm granule, 80 °C) → rotary dryer (direct-fired or indirect steam, outlet 60–70 °C, 1.5–2.5 % moisture) → rotary cooler (outlet 35–45 °C) → screener (on-size fraction to coating/storage, oversize to crusher, undersize to recycle).

### Ammonium Sulphate Crystallization and Drying
Dilute (NH₄)₂SO₄ solution 30–40 % → 4-effect forced-circulation evaporator → > 65 % solution → DTB crystallizer (85 °C) → centrifuge → fluid bed dryer (50–80 °C) → product > 99.5 % purity.

### Single Superphosphate (SSP) Drying
Den reaction product (SSP, 8–12 % free moisture, 15 % P₂O₅) → rotary dryer (direct-fired, 200–350 °C inlet) → cyclone → bag filter → product 3–5 % moisture → storage/granulation.

**Key challenge**: SSP is corrosive (free HF and HF-SiF₆ in exhaust gas) → bag filter material: PTFE membrane bags; scrubber: NaOH or Ca(OH)₂ packed-bed for HF and SiF₄ removal.

### Urea Fluid Bed Cooling
Prilling tower or granulation discharge (urea prills, 115 °C, 0.3–0.5 % moisture) → fluidized bed cooler (cooling air at ambient, 15 min residence) → outlet 40–45 °C → conditioner + storage.

## Emission Control in Fertiliser Plants

| Source | Contaminant | Lozzar Solution |
|---|---|---|
| NPK/granule dryer | PM dust (NPK particles), NH₃ | Cyclone + bag filter + wet NH₃ scrubber |
| SSP/TSP dryer | HF, SiF₄, PM | Bag filter (PTFE) + caustic scrubber |
| Ammonium sulphate dryer | PM, NH₃ | Bag filter + acid scrubber (H₂SO₄) |
| Urea granulator | NH₃, urea dust | Scrubber + acid wash |

All systems designed to meet IED BAT conclusions for the Large Volume Inorganic Chemicals (LVIC) sector and Fertilisers sector.

## Technical Challenges

- **Hygroscopic materials**: ammonium nitrate and CAN absorb moisture rapidly — all conveying and storage systems must be sealed and desiccated. Lozzar provides sealed screw conveyors and nitrogen-blanketed silos.
- **Explosion risk**: ammonium nitrate is classified explosive. Dryer and handling systems for AN require ATEX EX-Zone design with specific safety interlocks.
- **Corrosion**: HF in phosphate processing attacks carbon steel. Lozzar uses SS 316L or rubber-lined equipment for phosphate service.
- **Dust**: fertiliser dust is hygroscopic and can cake in bag filters. Lozzar specifies PTFE-coated filter bags and pulse-jet cleaning for this duty.

## Why Lozzar Process for Fertiliser Industry

- Experience with granule dryer + cooler + screener packages
- Ammonium sulphate crystallization and drying from caprolactam and coke oven by-products
- Acid gas scrubbing experience for phosphate fertiliser (HF, SiF₄)
- Single-source supply: dryer + cooler + bag filter + scrubber + conveyors
