Processes for SO2 removal vary depending on the amount of SO2 involved, the solution used to absorb the SO2, and the particular equipment used in the absorption tower.
- Applications with lower SO2 levels may need only one chevron level because of lower L/G ratios or other unique tower geometries.
- The majority of applications use a mist elimination zone that contains two stages of mist eliminators.
Koch-Glitsch offers many types of chevron mist eliminators for the numerous styles of absorbers and internal support arrangements.
FLEXICHEVRON® style VIII mist eliminators are designed specifically for FGD absorbers, but also work well in a variety of other applications, such as evaporators and cooling towers.
FLEXICHEVRON® style XII/XIV mist eliminators were developed for vertical up flow in high velocity absorber applications. This high capacity, two-stage design provides bulk removal by the first stage and fine removal by the second stage.
FLEXICHEVRON® style XXVII mist eliminators combine excellent efficiency and strength at an economical price. They can be used in single- or multi-stage applications. Style XXVII is available in polypropylene only.
FLEXICHEVRON® style XXVIII mist eliminators are used as a bulk separation device in a multi-stage mist eliminator design. Style XXVIII is available in polypropylene only.
