Problems solved by technology

Due to the high viscosity of residual oil, it is easy to adhere to the inner wall of the storage tank during storage. If it is not cleaned for a long time, it will corrode the inner wall of the storage tank, and even produce chemical substances to pollute the residual oil

Abstract

The invention discloses a cleaning agent for a residual oil storage tank and relates to the technical field of the petrochemical industry. The cleaning agent is prepared from raw materials in parts by weight as follows: 20-25 parts of palm oil, 10-15 parts of attapulgite, 10-15 parts of charcoal powder, 8-12 parts of polymerization ferric chloride, 6-11 parts of activated aluminum oxide, 5-8 parts of polyoxyethylene rosin ester, 5-8 parts of cetearyl alcohol, 4-6 parts of wollastonite powder, 4-6 parts of polyoxyethylene lauryl ether, 3-4 parts of an anti-rust auxiliary agent, 2-3 parts of asbestos wool, 2-3 parts of bamboo vinegar, 1-2 parts of sodium aluminosilicate, 40-50 parts of acetone and 150-200 parts of ethanol. The cleaning agent has a great cleaning effect on the residual oil storage tank, can completely remove residual oil and dirt attached to the inner wall of the storage tank, cannot corrode the storage tank and has an excellent anti-rust effect.

Description

Technical field: [0001] The invention relates to the technical field of petrochemical industry, in particular to a cleaning agent for residual oil storage tanks. Background technique: [0002] Residual oil refers to the residual oil obtained by vacuum distillation of crude oil, also known as vacuum residual oil. The heavy oil obtained from the bottom of an atmospheric distillation column is sometimes referred to as an atmospheric residue. The color is black and viscous, and it is semi-solid at room temperature. Its properties are related to the properties of crude oil. In petroleum refineries, residual oil is often used to process products such as petroleum coke, residual lubricating oil, petroleum asphalt, or as a cracking raw material. Due to the high viscosity of the residual oil, it is easy to adhere to the inner wall of the storage tank during storage. If it is not cleaned for a long time, it will corrode the inner wall of the storage tank, and even produce chemical ...
