Abstract

The invention relates to a cleaning agent for thickened oil conveying pipelines and a preparation method thereof, belonging to the technical field of cleaning agents. The cleaning agent for thickened oil conveying pipelines comprises the following components in parts by weight: 2-5 parts of rosemary, 10-20 parts of beer dreg, 1-2 parts of limonene, 2-6 parts of sodium diethylhexyl sulfosuccinate, 3-5 parts of fluorocarbon surfactant, 6-9 parts of cocamidopropyl betaine, 10-13 parts of isopropanol, 5-11 parts of pentaerythritol, 50-70 parts of ethyl acetate and 30-50 parts of water. The cleaning agent for thickened oil conveying pipelines adopts waste bear dregs as one of the raw materials and has the advantages of reasonable resource utilization, environmental friendliness and the like. The cleaning agent for thickened oil conveying pipelines is capable of thoroughly and rapidly removing oil scale, wax and the like out of oil conveying pipelines, the raw materials are free of strong acid and alkali substances, the oil conveying pipelines are not corroded, and meanwhile the cleaning agent is simple in preparation method, good in economic benefit and easy to popularize and apply.

Description

technical field [0001] The invention belongs to the technical field of cleaning agents, and in particular relates to a heavy oil pipeline cleaning agent and a preparation method thereof. Background technique [0002] The oil pipeline system, that is, the pipeline system used to transport oil and petroleum products, is mainly composed of oil pipelines, oil stations and other auxiliary related equipment. For transportation equipment, compared with railway and highway oil transportation, which are also land transportation methods, pipeline oil transportation has the characteristics of large transportation volume, good airtightness, low cost and high safety factor. [0003] At present, strong acid or strong alkaline cleaning agents are generally used for heavy oil pipelines in China. Since the cleaning process generally requires heating or cooking, the strong acid, strong alkali and solvent volatile components of the cleaning agent are difficult to rinse, which not only affects ...
