The petrochemical industry is referred to as petrochemical industry. The petrochemical industry is a basic industry. It provides supporting services and services for agriculture, energy, transportation, machinery, electronics, textiles, light industry, construction, building materials, and people's daily life. It plays an important role in the national economy. occupy a pivotal position in the

Petrochemical companies have a large number of chemical equipment, which are often placed in the open air, withstand high or low temperature conditions, and have corrosive or viscous production materials inside.

Common problems of petrochemical enterprise equipment:

1. When there is a lot of oil in the atmospheric dust, it will affect the heat transfer. Scale is the most common, and equipment with water or steam as the medium will form scale, with a large amount and a wide area.

2. The dirt generated by the chemical reaction is relatively firm, and if the wall temperature is too high, it will also cause coking. The dirt generated by corrosion products not only increases thermal resistance and pollutes products, but also increases surface roughness, further aggravating dirt deposition.

Regular cleaning of equipment can effectively prolong the service life of equipment, improve efficiency, ensure safety, and reduce unnecessary risks. At present, the latest cleaning method is to use dry ice blasting. The application range of dry ice blasting in petrochemical industry includes cleaning main fans, air compressors, smoke machines, steam turbines, blowers and other equipment, as well as various heating furnaces, reactors and other coking and coking removal. Clean the polyvinyl chloride resin on the heat exchanger; remove oil, rust, hydrocarbons and surface dirt on various pressure vessels such as compressors, storage tanks, and boilers; clean reactors and condensers; decontaminate complex bodies; Furnace tube cleaning, etc. The petrochemical industry uses dry ice blasting and can also be used to clean oil tanks.

Compared with the traditional cleaning technology in the petrochemical field, dry ice cleaning technology has the following characteristics:

1) No or only a small amount of solution is needed;

2) There are many kinds of attachments and substrates that can be cleaned;

3) It can effectively remove surface attachments with little damage to the substrate;

4) The cleaning area and quality can be controlled;

5) It can be made portable and has good mobility;

6) Easy to realize automatic operation;

7) The equipment has a long service life, only consumes electricity for operation, and the overall cost is low.
