Incoloy 825 Mesh Demister
The outstanding property of Incoloy 825 is its corrosion resistance. In both reducing & oxidizing conditions, Incoloy 825 resists general corrosion, pitting & crevice corrosion, intergranular corrosion and stress corrosion cracking. It is particularly useful in sulphuric & phosphoric acids, sulphur containing flue gases, sour gas and oil wells and sea water. High nickel content made it with effective stress corrosion cracking resistance performance.
Characteristics:
1. Good stress corrosion cracking resistance performance;
1. Good stress corrosion cracking resistance performance;

Applications:
Demister has been widely used in columns, evaporators, liquid-vapor separators, boilers, waste gas processing and compressor outlet for eliminating oil. It gets rid of the shortcomings of the traditional mist eliminators such as narrow operating range, low gas velocity, entrainment. Its operating range is about twice of traditional mist eliminators. The demisting efficiency is up to 100% for droplets of 5um or larger. According to the process, it can be installed in the existing equipment or made a standalone demister. Preferred applications:
To reduce loss of valuable products
To increase throughout capacity
To improve product purity
To protect compressors
