LimeGreen: falling film cross-flow green liquor filter
- Efficient separation of even small impurities
- High availability
- Less make-up lime required
- No need for lime mud precoat
- Long-life filter cloth
- Stable operation
The recausticizing process is the final stage in chemical recovery in a pulp mill. The goal is to achieve an efficient and controlled reaction between green liquor and lime to produce as much strong white liquor (NaOH) as possible with high purity for the cooking process and excellent lime mud filtration properties for the lime kiln.
ANDRITZ LimeLine recausticizing technology is central to the LimeLine white liquor plant. It is responsible for producing high-quality, homogenous white liquor with minimum alkaline loss and waste. The fully automated LimeLine recausticizing plant generates zero effluents. The equipment achieves high availability and reliability – making it the most cost-effective and environmentally sound technology for producing white liquor.
Reduced investment cost and a more compact footprint
Lower and more stable energy consumption
