Chrome Mist Eliminators
Chrome Mist Eliminators
Since the US EPA introduction of the chrome electroplating MACT standard back in the mid '90's, KCH Services has led the way in the development and manufacture of the most effective and efficient chromic acid mist eliminators in the industry, consistently meeting the EPA MACT standard. A properly designed chromic acid mist eliminator system takes into account all of the variables present in your specific application. The feasibility of tank covers, point of use capture, recovery and return to process tanks, integrity of duct system via inclusion of pre-control devices, and many other factors are considered in the design process of all KCH chrome mist eliminators.

Mesh Pad Mist Eliminators
Also known as mesh pad mist eliminators, chrome eliminators have become increasingly common throughout the local exhaust industries. This is due to their ability to meet the ever more stringent emission regulations administered by federal, state and local environmental enforcement agencies. Mesh pads are typically:
- of a structured weave design
- utilized in any number of configurations
- made up of strands of polypropylene woven filaments
- varied in degrees of density
Mesh Pad Elimination Process
As the air stream weaves its way through the layers, the liquid impinges upon the strands. The greatest success with these devices utilizes multiple stages with the first stage or two removing the largest liquid droplets. A coalescer stage is provided when the outlet emission requirement is stringent. The best performing composite mesh pad mist eliminators in use today utilize multiple stages, with the first stage being located at point of source of the entrained particulate. The remaining particulate is then removed down stream in the final stages. Orientation of the mesh material is important due to the varying degrees of the pads ability to handle liquid. The density of the pad material may cause flooding thru the pad.
Proper engineering techniques are vital to the success of these units. The vessels used would have spray header systems and automated wash down cycles to recover the liquids being captured and at the same time to keep the mesh pads from fouling.
