Problems solved by technology

[0003] However, the existing chemical cleaning agents are highly corrosive to pipelines, and the cleaning effect is not good. Some industrial chemical cleaning agents use some organic solvents with relatively large toxic and side effects. Although they have a better cleaning effect on pipelines, after cleaning The waste liquid has caused great pollution to the environment

Abstract

The invention relates to an oil-gas transmission pipeline cleaning agent and a preparation method thereof. The oil-gas transmission pipeline cleaning agent comprises the following components by weight: 28-36 parts of a Gleditsia Sinensis Lam extracted solution, 5-7 parts of polydimethylsiloxane, 6-9 parts of sodium carboxymethylcellulose, 10-16 parts of alkylphenol polyoxyethylene, 8-12 parts of ethylene glycol monobutyl ether, 15-20 parts of sodium chloride, 5-10 parts of citric acid, 4-8 parts of polyepoxysuccinic acid, 2-6 parts of potassium bitartrate, 5-12 parts of cetanol, 30-45 parts of ethanol, and 48-50 parts of water. The cleaning agent and the preparation method provided by the invention have the advantages that: 1. the cleaning agent provided by the invention has an excellent cleaning effect on pipelines, and can reach a clearance rate of 95% on dust and dirt in pipelines; 2. the raw materials involved in the invention are environment friendly and non-toxic, and have wide sources and low price; and 3. the preparation method provided by the invention is simple and feasible, and is convenient to implement, and the cleaning agent prepared by the method have stable properties and can be stored for a long time.

Description

technical field [0001] The invention belongs to the technical field of industrial cleaning agents, and in particular relates to an oil and gas pipeline cleaning agent and a preparation method thereof. Background technique [0002] At present, with the continuous growth of my country's oil industry, people are also doing a lot of research on oil-related industries. At present, my country's long-distance oil transportation is still dominated by pipeline transportation, most of which have been in operation for many years, and pipeline transportation is economical and environmentally friendly, with obvious advantages. However, due to the great impact and hidden dangers on the safe operation of pipelines such as wax formation and impurity precipitation, timely cleaning of oil pipelines is of great significance to their normal operation. Therefore, the cleaning of oil and gas pipelines is an extremely important process in the process of oil and gas transportation. At present, the...
