Description

technical field [0001] The invention relates to the technical field of cleaning agents, in particular to a heavy oil cleaning agent. Background technique [0002] At present, there are many types of cleaning products at home and abroad with different characteristics. Moreover, most cleaning agents contain solvent-based components to varying degrees. Even water-based metal cleaning agents without solvents cannot satisfy the cleaning effect under the premise of ensuring Requirements for environmental indicators. Especially for the high-risk and high-investment offshore oil industry, there is still no efficient and environmentally friendly cleaning agent for cleaning production facilities on offshore platforms. Therefore, the development and application of heavy oil cleaning agent is of great significance in my country's cleaning industry. Contents of the invention [0003] The purpose of the present invention is to solve the ...
