• Atmospheric Distillation: Dewatered crude coal tar is fed to the atmospheric distillation column where controlled heating progressively volatilizes and separates light oil, carbolic oil, naphthalene oil, and wash oil fractions as overhead distillate cuts, with heavy tar remaining as atmospheric still bottoms for vacuum distillation
• Vacuum Distillation: Atmospheric still bottoms are processed under vacuum in the vacuum distillation column, separating anthracene oil fractions and producing the primary coal tar pitch residue at the target softening point and quinoline-insoluble content specifications for the intended pitch grade
• Pitch Grade Finishing: Raw coal tar pitch from vacuum distillation is processed through thermal treatment, air-blowing, or blending operations to precisely adjust softening point, viscosity, coking value, and chemical composition to meet aluminum-grade, binder-grade, or specialty grade customer specifications
• Chemical Fraction Processing: Naphthalene oil fraction is cooled and crystallized to produce crude naphthalene cake for downstream naphthalene refining; carbolic oil is processed for phenol recovery; and light oil is stripped, washed, and rectified to yield crude benzene, toluene, and xylene fractions for sale to chemical processors
• Quality Testing and Grade Certification: Each pitch batch and chemical fraction lot is analyzed for softening point, viscosity, quinoline insolubles, toluene insolubles, coking value, density, sulfur content, and PAH composition before grade certification and customer release authorization
• Product Dispatch: Liquid pitch is dispatched in heated insulated tanker trucks or rail cars to aluminum smelter and electrode manufacturer customers; solid flaked or prilled pitch in bulk bags or drums to smaller industrial users; and chemical oil fractions in tanker trucks to chemical processing customers
