Semi-Dry System

Product catalog summary

Overview: The document describes the Semi-dry System for flue gas purification developed by Hitachi Zosen Inova AG. This system is designed to reduce reagent consumption, emissions, and residue levels while eliminating wastewater discharge. It features a compact design that minimizes investment and infrastructure costs.

Specifications: The system employs a circulating fluidized bed principle, using hydrated or calcined lime and activated carbon as reagents. It operates at temperatures below 160°C to enhance separation efficiency. The process is integrated with a turboadsorber and a fabric filter to trap pollutants.

Key Advantages:

Proven technology with a successful track record.
Efficient process with minimal investment requirements.
Compact equipment design allows for easy retrofitting.
Low maintenance due to minimal moving components.
High system availability due to generous design margins.
Low reagent consumption and residue levels.
High separation efficiency and low emissions.
No wastewater discharge and upgradable system.

Process Description: Flue gases are directed into the turboadsorber without pretreatment. Reagents and water are injected, causing a temperature drop that activates the lime. Pollutants react with the additives, forming products that are captured by the fabric filter. Residues are recycled to enhance separation efficiency and reduce reagent consumption.

Functional Diagram: The diagram illustrates the flow of materials through the system, including lime and activated carbon injection, water addition, raw gas entry, clean gas exit, recirculation, and residue management.

Conclusion: The Semi-dry System is ideal for energy-from-waste plants where compact design, minimal investment, and stringent emission standards are critical. It ensures high availability and low residue levels, making it a reliable choice for flue gas treatment.
