Abstract

The invention provides oil-based cleaning agent for petrochemical equipment. The oil-based cleaning agent is prepared from the following raw materials in percentage by mass: 9-12% of an emulsifiable penetrant, 1-2% of a penetrant, 1-2% of a non-ionic surfactant, 1-2% of a complexing agent, 1-1.5% of an antirust agent and the balance of an assistant. The cleaning agent is efficient, free of pollution and simple in operation process, is compatible with existing petrochemical equipment, and the cleaning and operating cost is lower. A system cleaned by the cleaning agent can reach a ferrous sulfide cleaning effect, and ferrous sulfide cleaning does not need to be carried out again. The cleaning agent does not contain a strong oxidant or a heavy metal ion of affecting sump oil recycling. The cleaning process is free of wastewater or a liquid waste and is free of corrosivity to equipment.

Description

technical field [0001] The invention relates to an oil-based cleaning agent used for cleaning petrochemical equipment, belonging 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 equipments in the atmosphere, environment, production raw materials, media, products, mechanical oil, etc., due to the physical, chemical, electrochemical or biological effects, the surface residues, deposits and generates various harmful effects on production operations and products. Pollutants or coatings that are harmful to quality or human health, this is industrial dirt. Therefore, oil scale and coke problems are common in petrochemical production, ...
