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). Comprehensive energy consumption per unit output of coal chemical products: 0.072 tce/t, the production system process is as follows: coal tar - dehydration - vacuum distillation (product: carbon black oil) - distillate washing (product: dephenolized phenol oil and dephenolized light oil) - (1) Phenolate decomposition (product: crude phenol), (2) Naphthalene distillation unit (product: industrial naphthalene and washing oil). (Data statistics cycle:(3)Modified asphalt :carbon black oil (soft asphalt → pretreatment (product: anthracene oil) → asphalt modification → asphalt tank (product: liquid modified asphalt) → curing molding (product: solid modified asphalt). (4) Phthalic anhydride : air preheating → vaporization of raw materials → oxidation reactor → condensation → pretreatment t→ rectification → flake crystallization → (Product: phthalic anhydride) (Data statistical period: From Jan.01, to Dec. 31, 2023)
煤化工产品（涉及资质按资质范围）生产涉及的能源管理活动。 煤化工产品单位产量综合能耗：0.072tce/t，生产系统工艺为： 煤焦油→脱水→减压蒸馏（得产品：炭黑油）→馏分洗涤（得产品：脱酚酚油、脱酚轻油）→①酚盐分解（得产品：粗酚）、②萘蒸馏装置（得产品：工业萘、洗油）。③改质沥青： 炭黑油（软沥青→预处理（得产品：蒽油）→沥青改质→沥青大槽（得产品：液态改质沥青）→固化成型（得产品：固体改质沥青）④苯酐：空气预热→原料汽化→氧化反应→冷凝→预处理→精馏→结片→（得产品：苯酐）。 （数据统计周期：2023年01月01日～12月31日)
