Abstract

The invention relates to a preparation method of a long-acting inner wall cleaning agent for a crude oil storage tank, and belongs to the technical field of chemical engineering cleaning agents. The method comprises the steps that a sulfuric acid solution, a polyethylene oxide-polypropylene oxide segmented copolymer, urotropine, o-xylene thiourea, sodium molybdate, triisopropanolamine, isobornyl methacrylate, benzoic acid and olive oil macrogol ester are heated and then mixed to be uniform, and a first mixture is obtained; a corrosion inhibitor and a thickening agent are added in the first mixture, heated and mixed to be uniform, and a second mixture is obtained; an anion surface active agent and paraffin emulsion are added into the second mixture, heated and then mixed under the high-speed dispersion condition, and a cleaning agent is obtained. According to the cleaning agent, the problem that iron sulfide surface depositions and corrosion are generated by a sulfur compound in the crude oil storage tank can be solved, and the cleaning agent has the effect of resisting rust in a long-acting mode.

Description

technical field [0001] The invention relates to a preparation method of a long-acting inner wall cleaning agent for crude oil storage tanks, belonging to the technical field of chemical cleaning agents. Background technique [0002] According to the national oil tank repair regulations, the storage tank overhaul interval is 5 to 7 years, and it must be cleaned before repairing or changing the oil type. Before the mid-1990s, the cleaning of oil tanks was done manually, which not only wasted a lot of energy, but was also unsafe and caused environmental pollution. After our research, the current national crude oil storage tank storage capacity (strategic and commercial) is more than 100 million tons. According to the industry standard 5-year cleaning cycle, there will be 20 million tons per year (average 50,000 tons / seat, there will be 400) The above crude oil storage tanks need to be cleaned. Due to the utilization of sulfur-containing crude oil, sulfur corrosion and its a...
