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;
2. Good resistance for pitting and crevice corrosion performance;
3. Good anti-oxidation and non-oxidizing heat acid 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
To deal with condensates
To reduce down sream corrosion and fouling
To prevent air or water pollution Features:
High efficiency, wide operation range, easy installing, low cost.
