Emission control for fluid catalytic cracking units
Refineries face significant challenges in controlling emissions, particularly sulfur dioxide and particulate matter, from Fluid Catalytic Cracking (FCC) units. Effective emission control is crucial to meet environmental regulations and ensure operational efficiency.
Reduce emissions with electrostatic precipitation and scrubbing
The EP Absorber by GEA is designed for gas cleaning in FCC units. It combines absorption and electrostatic precipitation to lower emissions. The flue gas first enters the wet scrubber where it cools and absorbs sulfur dioxide. Next, the electrostatic precipitator removes particulate matter and sulfuric acid mist. This compact unit can handle inlet gas temperatures up to 600°C without the need for additional booster fans or boiler reinforcements. Key features include long-lasting discharge electrodes, redundant T/R sets, and controllers. The materials, such as Polypropylene (PP) and Polyvinylchloride (PVC), are chosen to withstand high temperatures and stresses, ensuring durability and efficiency.
Benefits
- Lower emissions compared to conventional SO2 scrubbers
- Less energy consumption due to low pressure drop
- Compact design combining multiple processes
- High durability with heavy-duty electrodes
- Suitable for high-temperature gas up to 600°C
