FIELD: process engineering.
SUBSTANCE: invention relates to cleaning the inside of various process equipment used in gas industry, particularly, to cleaning the inside of multicyclone dust trap of dirt composed of compacted fine fraction with mineral, polymer and metallic inclusions. For cleaning purposes, filling of dust trap inside with dirt is evaluated to perform its cleaning by air-impact device proceeding from the results of said evaluation. Then, chemical cleaning is performed by solution of surfactants along with hydraulic cleaning by high-pressure nozzle.
EFFECT: expanded range of hardware.
