Hydrated Lime Injection
FLSmidth's Hydrated Lime Injection (HLI) system reduces SO2 emission by up to 60%.
- Effective emission control
- Easy operation
- Highly reliable
How it works
The hydrated lime powder absorbs SO2. FLSmidth provides either a pneumatic solution, or a mechanical solution that meters hydrated lime powder via a dosing system connected to the kiln feed.
The HLI system is a cost-effective solution for handling periodic fluctuations in SO2 emission levels to remain within legal compliance limits. The hydrated lime usually absorbs up to 60% of the SO2 in the gases if injected at the correct temperature. If higher SO2 reductions are needed, FLSmidth's Gas Suspension Absorber (GSA) should be considered.
