The role of coal tar cleaning agent in the maintenance of coal chemical production equipment


The coal chemical industry involves the transformation of coal into gas, liquid, and solid fuels as well as various chemicals through chemical processing. This includes processes such as coal gasification, liquefaction, dry distillation, tar processing, and calcium carbide acetylene chemistry. The organic structure of coal consists of a core of aromatic rings connected by bridges, forming a macromolecular structure with diverse functional groups. Through thermal and catalytic treatments, coal can be converted into a wide range of fuels and chemical products. Coking is one of the earliest and most significant methods, primarily used to produce coke for metallurgical purposes, along with by-products like gas and aromatic hydrocarbons such as benzene, toluene, xylene, and naphthalene.

During the production process in coal chemical plants, equipment such as heat exchangers, condensers, oil furnace pipes, distillation towers, and benzene washing towers are widely used. However, over time, coal tar adhesion, coking, and carbonization can cause operational issues and reduce efficiency. To address this, we recommend Kaidi KD-L214 Coal Tar Cleaner, an advanced cleaning agent developed by Shandong Kaidi Company. This product is designed to effectively remove coal tar and coke while ensuring safety and environmental friendliness.

Kaidi KD-L214 is a high-performance, eco-friendly cleaner that quickly dissolves coal tar and carbon deposits without damaging metal surfaces. It features excellent penetration and emulsification properties, making it easy to use and highly efficient. With a neutral pH of 7, it is safe for most metals and leaves no residue after evaporation. The product has been tested and certified by SGS, ensuring its quality and reliability. It is non-flammable, non-explosive, and non-toxic, offering a fast dissolution rate and low volatility—making it ideal for industrial applications.

Key Features: 1. Strong degreasing and decontamination performance, capable of dissolving up to 60-80% of oils. 2. Safe, easy to use, and highly efficient. 3. Neutral pH (7), non-corrosive to most metals. 4. Residual liquid evaporates completely, leaving no trace. 5. Non-flammable, non-explosive, non-toxic, and environmentally friendly. 6. Faster at dissolving coke and slower at evaporation compared to similar products.

Applications: - Cleaning heavy grease and sludge in petrochemical, industrial, mining, repair, printing, and shipbuilding industries. - Removing coal tar from pipelines, intercoolers, and oil separators in coking plants. - Cleaning tar scale and condensed aromatic hydrocarbon deposits in gas pipelines, heat exchangers, compressors, air compressors, and vacuum pumps across chemical, steel, machinery, and metallurgy sectors. - Cleaning oil tanks and internal walls using spray or immersion methods. - Cleaning reaction vessels, oil pipes, and sealed containers with a corrosion-resistant pump, or immersing scattered parts in the cleaner.

Packaging Options: 25 kg plastic drum, 250 kg iron drum, and 5 kg iron drum (sample size).
