Cleaning agent compositions used for gas turbine air compressors

摘要

According to the present invention there is provided a cleaning agent composition capable of removing the foulants deposited in gas turbine air compressors even during their operation and thereby cleaning the compressors. That is, there is provided a cleaning agent composition comprising (A) a solvent component consisting of a combination of a particular monovalent aliphatic alcohol-ethylene glycol adduct and a particular phenol-ethylene glycol adduct, and (B) a surfactant component consisting of a combination of a particular polyethylene glycol mono(alkylphenol) ether and an ammonium or amine salt of a particular fatty acid. Said composition is diluted with purified water and used for cleaning of gas turbine air compressors, particular their turbine blades. The cleaning agent composition has high cleaning power; the gas turbine unit of the compressor cleaned with the composition is not liable to undergo secondary fouling or adverse effect because the composition scarcely remains thereon after cleaning; and the composition further has a rust-preventive effect for the compressor.
