Metallic slag oil-water base cleaning agent

Abstract

The invention provides a metallic slag oil-water base cleaning agent. The cleaning agent uses water as a solvent, and is characterized by comprising the following components by weight percent: 0.5-10% of a nonionic surfactant, 1.0-2.0% of an anionic surfactant, 1-5% of a dispersant, 0.4-10% of a compound corrosion inhibitor, 0.1-3% of a defoaming agent, and 52-97% of water. Under the normal temperature condition, the metallic slag oil-water base cleaning agent has high cleaning rate, and is capable of well replacing an organic solvent type cleaning agent, is free from corrosion to the metal, easy to prepare in use, simple in operation, free from combustion and explosion, safe and non-toxic.

Description

technical field [0001] The invention relates to a cleaning agent, in particular to a metal residue oil water-based cleaning agent. Background technique [0002] At present, in actual production, metal equipment and pipelines need to be cleaned of oil regularly. A large amount of residual oil, oil slurry, oil sludge, dust and other substances are often accumulated on the surfaces of containers, heat exchangers, pipelines, sedimentation towers and other parts of the refining unit. These dirts affect the normal operation of the device and increase the risk of construction. Therefore, regular cleaning and maintenance of the device can keep them in normal operation. Scaling of heat exchangers is currently a common problem in the decompression unit of refineries. Scaling leads to a decrease in the final temperature of heat exchange, waste of fuel, and increases the difficulty of operation. [0003] In recent years, the metal cleaning agent industry has achieved rapid development...

AI Technical Summary

Problems solved by technology

These dirt affect the normal operation of the device and increase the risk of construction, so regular cleaning and maintenance of the device can keep them in normal operation

Scaling of heat exchangers is currently a common problem in decompression units of refineries. Scaling leads to lower final heat exchange temperature, waste of fuel, and increased operational difficulty

[0003] In recent years, the metal cleaning agent industry has achieved rapid development, and there are many types, but the solid metal cleaning agent has poor solubility, and the cleaning effect at room temperature is not ideal. It needs to be cleaned at elevated temperatures, and this type of metal cleaning agent is often alkaline Strong, easy to cause damage to the metal surface

At present, many water-based metal cleaning agents have come out, but there are still many problems that need to be improved in terms of cleaning temperature, anti-corrosion, anti-rust, high efficiency and environmental protection, and cannot completely replace solvent-based metal cleaning agents. limit
