Problems solved by technology

At present, the commonly used cleaning agents for such oily dirt are alkaline aqueous solution, but most of them are poor in removing mineral oil dirt, so they can only be used as daily degreasers; organic solvents, commonly used petroleum solvents, halogenated hydrocarbon solvents and alcohol solvents etc. Although it has good solubility to oil stains, it is flammable, volatile and toxic, so it should be used with caution
Surfactant solution has unique functions of reducing surface tension, wetting and penetrating, emulsifying, dispersing and solubilizing, etc. It has good ability to remove liquid oil stains, but poor ability to remove solid oil stains

Abstract

The invention discloses an efficient and pollution-free industrial cleaning agent as well as its preparation method and application. The formula of cleaning agent includes 80%~93% mixed ester solvent, 2%~5% nonionic surfactant, 3%~10% sodium carbonate Na2CO3, 2%~10% sodium silicate Na2SiO4. Its preparation method is to add mixed ester solvent first, then add nonionic surfactant, sodium carbonate Na2CO3, sodium silicate Na2SiO4 at the same time, and then manually or mechanically stir for 15 to 20 minutes to obtain an efficient and pollution-free industrial cleaning agent of the present invention. agent. The cleaning agent of the present invention is suitable for the cleaning of the oil circuit system in which the operating medium is oil, and is especially suitable for the cleaning of petrochemical equipment and all industrial equipment such as on-line cleaning or disassembly and cleaning of the compressor oil circuit system. The cleaning agent of the present invention has no influence on equipment system, product quality and catalyst performance.

Description

technical field [0001] The invention relates to an efficient and pollution-free industrial cleaning agent and its application. Background technique [0002] In industrial petrochemical production, the refining production mainly adopts atmospheric and vacuum distillation units and subsequent units for deep processing, such as ethylene cracking, catalytic cracking, delayed coking, aromatics combination, hydrofining and other units. During the production process, many equipment will accumulate Polymerizes to form grease and scorch. It will also occur in the deposit of dirt in the crude oil tank and the adhesion of oil dirt on the wall of the oil pipeline. Therefore, oil and coke problems are common in petrochemical production; in addition, all industrial manufacturing equipment oil circuit systems, such as air compressor oil circuit systems, also commonly have oil sludge, coke and other phenomena. The generation of grease and coke can increase the heat conduction resistance ...
