## Key Process Lines

### Paper Mill Sludge Drying
Dewatered primary + secondary sludge (20–30 % DS) from belt press or centrifuge → belt dryer (60–120 °C, low temperature) → 70–85 % DS dried sludge → incineration in bark boiler or co-incineration facility.

**Why belt dryer**: paper sludge is sticky and fibrous — unsuitable for flash dryer; belt dryer handles lump/sheet form; low temperature avoids dioxin formation risk in direct-fired dryers; easy odour containment.

### Black Liquor Evaporation (Kraft Pulp)
Weak black liquor (15–20 % DS from washing plant) → 7-effect falling-film evaporator → 65–70 % DS heavy liquor → recovery boiler.

**Steam economy**: 6-effect system evaporates 6 kg water per kg steam. Energy integration with existing mill steam network. Lozzar Process scope: 1–5 effect systems (upgrading or supplementing existing evaporator trains).

### Bark Biomass Boiler Waste Heat Recovery
Bark boiler flue gas (200–300 °C after economiser) → HRSG (hot water, 90 °C) → district heat or dryer heat source → flue gas to bag filter → electrostatic precipitator → stack.

### Wood Chip Drying for Pulp Mill Energy
Wet bark and wood waste (50–60 % moisture, from chipping) → belt dryer or rotary dryer (using low-pressure steam 4 bar from mill) → dried fuel at 20–25 % moisture → biomass boiler → improved boiler efficiency +15–20 %.

## Energy Integration in Paper Mill Environment

Paper and pulp mills have abundant low-grade steam and hot water — ideal for integration with drying systems:
- Low-pressure steam (3–6 bar) from condensate flash → belt dryer or evaporator heat input
- Hot condensate (90–130 °C) → heat exchanger → drying air preheating
- Evaporator vapour condensate (clean water) → process water reuse
- Bark boiler flue gas (>200 °C) → WHR system → hot water for belt dryer

This integration achieves near-zero additional fuel input for sludge drying or black liquor concentration.

## Emission Control for Paper Industry

| Source | Contaminant | Lozzar Solution |
|---|---|---|
| Bark / biomass boiler | PM, CO | Cyclone + bag filter (or ESP) |
| Sludge dryer exhaust | PM, odour (H₂S, mercaptans) | Condenser + biofilter or RTO |
| Black liquor recovery boiler | SO₂, H₂S, TRS | Scrubber (caustic or lime) |
