Problems solved by technology

[0002] After the oil storage tank has been used for a period of time, the impurities in the crude oil will deposit on the bottom and wall of the tank, which will reduce the effective capacity of the oil storage tank and affect the efficiency of the oil storage tank. Therefore, the oil storage tank needs to be inspected, repaired and cleaned regularly Internal sludge, the current domestic traditional oil tank cleaning method mainly uses manual labor, and manual tank cleaning has problems such as high labor intensity, long construction period, poor safety, low crude oil recovery rate, and environmental pollution

Abstract

The invention relates to a preparation method for a cleaning agent for a crude oil storage tank, and belongs to the technical field of crude oil equipment cleaning. The preparation method comprises the following steps that oleic acid, lipase, pine needle essential oil, sodium metasilicate pentahydrate, sodium alkylarylsulfonate, tetraacetylethylenediamine, palmitic acid, fulvic acid and glycerol monolaurate are heated and then are uniformly mixed so as to obtain a first mixture; a cationic surfactant and polyethylene glycol are added into the first mixture, and after heating is carried out, uniform mixing is carried out so as to obtain a second mixture; and an anionic surfactant and sodium pyrophosphate are added into the second mixture, and after heating is carried out, mixing is carriedout under a high-speed dispersing condition so as to obtain the cleaning agent.

Description

technical field [0001] The invention relates to a preparation method of a cleaning agent for crude oil storage tanks, belonging to the technical field of chemical cleaning agents. Background technique [0002] After the oil storage tank has been used for a period of time, the impurities in the crude oil will deposit on the bottom and wall of the tank, which will reduce the effective capacity of the oil storage tank and affect the efficiency of the oil storage tank. Therefore, the oil storage tank needs to be inspected, repaired and cleaned regularly Internal sludge, the current domestic traditional oil tank cleaning method mainly uses manual labor, and manual tank cleaning has problems such as high labor intensity, long construction period, poor safety, low crude oil recovery rate, and environmental pollution. With the construction of a large number of large oil storage tanks in my country and the increasing emphasis on environmental protection issues, manual cleaning of tan...
