Multicon dust arresters are designed to filter gas from mechanical particles and condensate and provide filtering fineness starting from 40 μm and find their use as a part of various skids and assemblies, such as automated gas distribution skids, startup and instrument gas treatment plants, and booster compressor stations. Dust collectors themselves appear as vertical makes with multicyclone dust catches placed on top with the following operation philosophy:
- gas flowing through flow swirls (cyclones) around the inner axis of cyclone pipes, while
- the impact of centrifugal forces has particles and mist separated from gas flowing down to the conical section of dust arresters and settled to rid of all the foreign mixes;
- gas free of dust and liquids flows via the inner tubing ща cyclones and ends up in the upper vessel to leave the purified.
