Coal tar quality

The quality of coal tar is influenced by various factors, which may be amplified as coke ovens become larger. The following are possible influencing factors: 1. Coal quality: The quality and type of coal are the main factors affecting the quality of coal tar. The properties of coke and coal tar produced from different types and qualities of coal vary greatly. High-quality coal can produce high-quality coal tar. 2. Coking process: includes coking temperature, blast speed, coal layer thickness, etc. These parameters will directly affect the carbonization process as well as the yield and quality of coal tar. After the enlargement of coke ovens, these parameters need to be re-optimized to ensure the quality of coal tar. 3. Equipment: The output and quality of coal tar are also affected by equipment. For example, the size and efficiency of the equipment, as well as its maintenance and operation, all affect the quality of coal tar. With the enlargement of coke ovens, larger equipment may lead to uneven distribution of factors such as temperature and pressure, thereby affecting the quality of coal tar. 4. Operators: The technical skill level and operating practices of the operators also affect the quality of coal tar. Skilled operators can better control the coking process to improve the quality of coal tar. 5. Treatment of coke oven gases: Large-scale coke ovens may generate larger volumes of coke oven gases; the manner in which these gases are treated can affect the quality of coal tar. For example, components such as toluene and quinoline in the flue gas may be lost during the treatment process, thereby reducing the quality of coal tar. .
