METHOD OF CLEANING OF GAS TURBO-COMPRESSORS Russian patent published in 1994 - IPC

FIELD: detergents. SUBSTANCE: gas turbo-compressor setting is flushed twice. The first flushing is performed by a solution containing, mass percent: mixture of oxyethylated isononyl phenol ( with a level of oxyethylation within 6 to 8 ) and alkyl phenol 0.5-5.0, petroleum solvent 0.5-20.0, sodium tripolyphosphate 0.1-0.2 and water up to 100. The second flushing is carried out with a 0.002-0.1-percent solution of sodium tripolyphosphate or sodium silicate, or with their mixture at a mass relation of 1: (1-3). These conditions allow the gas turbo-compressor to be flushed at a detergent temperature ranging from 20 to 30 C without preheating of the surface to be cleaned, which should be performed in the said case ( up to 50-60 C). After flushing the surface is coated with a protective film that prevents sticking of oil contaminants, which increases the interval between flushings or allows less concentrated detergents to be used. EFFECT: enhanced effect of flushing at cheapened procedure and fire safety. 1 tbl
