Certificate Number: ENMS 702375
Scope: The energy management activities for the manufacture of coal chemical products (the product with qualification requirement should be limited in its qualification certificate). The comprehensive energy consumption per unit processing capacity of the tar plant is 34.96kgtce/t, that of the modified asphalt plant is 32.49kgtce/t, and that of the phthalic anhydride plant is 87.59kgtce/t. Tar plant production process: Coal tar → dehydration → vacuum distillation (product: carbon black oil) → Fraction washing (product: dephenolized oil) → phenolic salt decomposition (product: crude phenol), naphthalene distillation (product: industrial naphthalene, washing oil), blending: mud gun oil. Production process of modified asphalt plant: Carbon black oil (soft asphalt → pretreatment (product: anthracene oil) → asphalt modification → large asphalt tank (product: liquid modified asphalt) → curing and shaping (product: solid modified asphalt). Production process of phthalic anhydride plant: Air preheating → raw material vaporization → oxidation reaction → condensation → pretreatment → distillation → flake formation → (Product: phthalic anhydride) (Data statistical period: From Jan.01, to Dec. 31, 2024)
