Problems solved by technology

[0004] At present, in China, soda ash, oily solvent, strong acid or strong alkaline cleaning agents are generally used to clean the inner and outer walls of oil pipelines, mechanical equipment and their parts. Alkali and solvent volatile components are difficult to rinse, which not only causes great harm to the environment, equipment and human body, but also brings certain safety hazards

Abstract

The invention discloses an oil pipeline detergent and a preparation method thereof, belonging to the technical field of industrial detergents. The oil pipeline detergent comprises the following components in parts by weight: 2-5 parts of gallnuts, 1.5-3 parts of small cyrtomium fortunei, 1-2.5 parts of sodium glycyrrhizinate, 3-6 parts of pomegranate barks, 2-4 parts of sodium tripolyphosphate, 0.1-1 part of sodium metasilicate pentahydrate, 10-13 parts of sodium diethylhexyl sulfosuccinate, 4-12 parts of iso-tridecanol polyoxyethylene ether, 1-3 parts of urotropin, 0.5-5 parts of nonionic fluorocarbon surfactant, 2-5 parts of fatty alcohol polyoxyethylene ether, 1-2 parts of scale inhibitor and 120-150 parts of water. The preparation method is simple; the prepared oil pipeline detergent can be used for rapidly and thoroughly removing oil dirt, wax and the like on an oil pipeline; in addition, the raw materials of the oil pipeline detergent contain no strong acid and alkaline substances, and water is used as a solvent, so that the oil pipeline detergent is free of corrosion to crude oil equipment, is free of injury to human bodies, is safe and environment-friendly and is easy to popularize and apply.

Description

technical field [0001] The invention belongs to the technical field of industrial cleaning agents, and in particular relates to an 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] The pipes of oil pipelines are generally steel pipes, which are connected to long-distance pipelines by welding and flange connection devices, and valves are used for opening and closing control and flow regulation. Oil pipelines mainly include isothermal transportation, heating transportation and sequ...
