Problems solved by technology

[0003] At present, the cleaning of crude oil pipelines in China mainly uses some strong acidic or strong alkaline chemical cleaners, which not only have poor cleaning effect, but also cause secondary pollution to the environment, and are highly corrosive to crude oil pipelines , which reduces the service life of the pipeline; in addition, the cleaning effect of this type of cleaner is extremely poor at low temperatures

Abstract

The invention discloses a preparation method for cleaning agent for industrial crude oil pipelines. The cleaning agent prepared according to the method is composed of the following components in parts by weight: 5-8 parts of active silicon micro powder, 2-6 parts of anhydrous sodium sulfite, 4-8 parts of sodium citrate, 2-5 parts of sodium dodecyl sulfate, 1-3 parts of potassium bitartrate, 12-22 parts of methylal, 5-10 parts of ethanol, 3-9 parts of p-hydroxybenzoic acid, 3-5 parts of an anti-oxidant, 4-9 parts of a surfactant, 3-7 parts of an antirust agent, and 50-60 parts of deionized water. The cleaning agent for crude oil pipelines is strong in industrial crude oil removal capability, free of toxicity, good in cleaning effect, safe and environment-friendly, possesses antirust protective effect on crude oil pipelines, and prolongs the service life of equipment.

Description

technical field [0001] The invention relates to a preparation method of an industrial crude oil pipeline cleaner, belonging to the technical field of cleaners. Background technique [0002] In oil extraction operations, many oil pipelines are often contaminated by crude oil. If the cleaning is not thorough, the oil pipelines will be blocked or even corroded, which not only affects the use effect of the equipment, but also reduces the service life of the pipelines. The construction scale of crude oil pipelines in my country is also expanding day by day, and the cleanliness of crude oil pipelines has always been a problem that cannot be ignored in the process of crude oil transportation. [0003] At present, the cleaning of crude oil pipelines in China mainly uses some strong acidic or strong alkaline chemical cleaners, which not only have poor cleaning effect, but also cause secondary pollution to the environment, and are highly corrosive to crude oil pipelines , reducing th...
