Abstract

The invention discloses a water-based detergent used for cleaning petrochemical devices. The water-based detergent comprises, by mass, 10-13% of a natural fatty alcohol and ethylene oxide polymer, 18-22% of a furan derivative, 15-19% of a chelating agent, 0.1-0.2% of a complexing agent, 2-3% of a rust and corrosion inhibitor, and the balance of water. The water-based detergent overcomes the shortcomings of high corrosion, low cleaning factor and poor safety of present water-based detergents, and has the advantages of good cleaning effect, high decontaminating and cleaning ability, no damages or corrosion to cleaned workpieces, safety in use, and nontoxicity and innocuousness.

Description

technical field [0001] The invention relates to a water-based cleaning agent used for cleaning petrochemical equipment, which belongs to the technical field of petrochemical industry. Background technique [0002] In the industrial petrochemical production, the refining production mainly adopts the atmospheric and vacuum distillation unit and the follow-up unit of deep processing, such as ethylene cracking, catalytic cracking, delayed coking, aromatics combination, hydrofining and other units. During the contact process of these equipment in the atmosphere, environment, production raw materials, media, products, mechanical oil, etc., due to physical, chemical, electrochemical or biological effects, residues, deposition and formation of various substances on the surface of the equipment are harmful to production operations and products. Pollutants or coatings that are harmful to quality or human health, this is industrial dirt. Therefore, oil scale and coke scale problems ar...
