Problems solved by technology

[0004] 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. The volatile components of the solvent are difficult to rinse, which not only causes great harm to the environment, equipment and human body, but also brings certain safety hazards. In addition, the residual cleaning agent will seriously pollute the oil, and even cause serious accidents

Abstract

The invention discloses a heavy-oil delivery pipeline cleaning agent and a preparation method thereof and belongs to the technical field of oil pipeline cleaning. The heavy-oil delivery pipeline cleaning agent is prepared from the following components in parts by weight: 2-4 parts of corn stigma, 3-5 parts of argy wormwood leaves, 1-2 parts of holboellia latifolia wall, 8-12 parts of polyoxyethylene lauryl ether, 7-10 parts of polyoxyethylene castor oil, 6-8 parts of docusate sodium, 2-5 parts of gellan gum, 1-2 parts of sodium citrate, 0.1-0.5 part of polyquaternium, 0.5-1 part of dimercapto ethylglycine, 1-2 parts of polymaleic anhydride which serves as an inhibitor, 20-30 parts of ethanol and 50-60 parts of water. The heavy-oil delivery pipeline cleaning agent disclosed by the invention can be used for removing 99% of oil and wax of the heavy-oil delivery pipeline thoroughly and rapidly and has a good scale inhibiting effect in the subsequent use process so that the cleaning cycle can be prolonged greatly. In addition, the heavy-oil delivery pipeline cleaning agent does not contain strongly acidic or alkaline substances, can not corrode crude oil equipment, is harmless to the human body and is suitable for large-scale production.

Description

technical field [0001] The invention belongs to the technical field of petroleum pipeline cleaning, and in particular relates to a heavy oil pipeline cleaning agent and a preparation method thereof. Background technique [0002] Heavy oil is the remaining heavy oil after gasoline and diesel oil are extracted from crude oil, which is characterized by large molecular weight and high viscosity. The specific gravity of heavy oil is generally 0.82-0.95, and the calorific value is about 10000-11000kcal / kg. Its main components are hydrocarbons, and it also contains about 0.1-4% sulfur and trace amounts of inorganic compounds. [0003] The oil pipeline system, that is, the pipeline system used to transport petroleum and petroleum products, is mainly composed of oil pipelines, oil stations and other auxiliary related equipment. It is one of the main equipment in the oil storage and transportation industry. At present, oil pipelines have become the main It is one of the transportatio...
