Description

technical field

[0001] The invention relates to a cleaning agent, its preparation method and its application in cleaning heavy oil dirt and carbon deposits in industrial pipelines or compressors. Background technique

[0002] The main component of heavy oil dirt and carbon deposits is colloid, which is closely combined with metal, and it is difficult to be removed by general solvents. Industrial pipe cleaning has always been an important part of the industrial energy conservation and environmental protection industry, and plays an important role in guaranteeing the implementation of the national low-carbon energy-saving policy. During the operation of industrial pipelines, there is a common problem of fouling deposition, which is very harmful. With the thickening of the scale layer, the thermal resistance of the scale layer will become the main factor affecting the heat transfer rate, which will reduce the efficiency of the equipment; serious scaling hazards will lead to sh...
