Abstract

The invention discloses oil removal powder for cleaning a stainless steel filter element for petroleum refining. The oil removal powder comprises a component A and a component B, the component A comprises the following components in parts by weight: 25-30 parts of sodium hydroxide, 15-20 parts of sodium lignin sulfonate, 15-20 parts of sodium carbonate, 5-10 parts of borax, 5-10 parts of sodium dodecyl benzene sulfonate, 3-5 parts of cocoanut fatty acid diethanolamide, 3-5 parts of an emulsifier AES and 3-5 parts of an emulsifier TX-10; the component B is prepared from the following components in parts by weight: 20 to 30 parts of an emulsifier AEO-9, 20 to 30 parts of sodium dodecyl benzene sulfonate, 5 to 10 parts of perfluorononenoxy sodium benzenesulfonate, 5 to 10 parts of alkyl glycoside APG, 10 to 15 parts of a fluorine-containing polycarboxylic acid dispersant, 5 to 10 parts of hydrolytic polymaleic anhydride and 3 to 5 parts of sodium citrate. The oil removal powder can fully remove residual oil on the surface and in the stainless steel filter element, and the cleaning effect is good.

Description

technical field [0001] The invention relates to the technical field of metal cleaning, in particular to a degreasing powder used for cleaning stainless steel filter elements in petroleum refining and a cleaning method. Background technique [0002] Refining is a process in which crude oil is processed through a series of processes to obtain useful petroleum products such as kerosene, gasoline, diesel, and chemical raw materials such as olefins and aromatics. In petroleum refining and chemical processing, the filtration of crude oil is an essential process. The filter element used in the crude oil filter is generally a stainless steel filter element. After a period of filtration treatment, it is prone to blockage. In order to ensure the service life of the filter element, the cleaning of the filter element is very important. However, for petroleum refining stainless steel filter elements, the composition of impurities that block the filter element is more complex. In additio...
