Efficient flue gas cleaning for compliant and stable industrial processes
The exhaust gases from power plants, waste incineration plants and chemical production plants contain relevant pollutants such as sulphur dioxide (SO2) and nitrogen oxides (NOX). Effective flue gas cleaning is therefore crucial for environmental compatibility, permit compliance and economical plant operation.
Depending on the process requirements, combined processes are used: in DeNOX plants, nitrogen oxides are specifically reduced to nitrogen and water, while in flue gas desulphurisation plants, sulphur dioxide is reliably removed or - in sulphuric acid production, for example - recovered and returned to the production cycle.
The precise control of these cleaning processes minimises emissions in the long term, stabilises plant performance and ensures long-term legally compliant operation.
Challenges in flue gas cleaning
- Exceeding emission limits jeopardises operating licences.
- Fluctuating flue gas compositions make stable process control difficult.
- Insufficient dosing accuracy reduces cleaning performance.
- Complex handling of solids increases operating and maintenance costs.
- Inefficient processes cause higher operating and chemical costs.
The solution from sera
- Targeted NOX reduction: Dosing of ammonia or urea for effective reduction of nitrogen oxides in the cleaning process and dosing of milk of lime for efficient flue gas desulphurisation.
- Reliable preparation technology: Transfer of granulate or flakes into preparation tanks - manually, semi-automatically or fully automatically.
- Reliable system technology for suspensions: PP container with conical bottom, agitator, low dead space fittings and automatic flushing device.
- High process reliability: Reliable dosing into the waste gas cleaning system thanks to redundant systems and high-quality measurement technology.
- Flexible integration: Adaptable to different system sizes and degrees of automation.
The dosing systems from sera ensure stable and reliable NOX reduction and clean gas desulphurisation, ensure compliance with legal emission limits and enable environmentally friendly, permit-compliant and economical operation of power plants.
