Discharge and Disposal of Coking Residue and Distribution Characteristics of PAHs in it

Abstract:

The research studied the treatment ways of discharging coking residues and the distribution characteristics of PAHs in two kinds of typical coking residues. The outputs of coal tar (100,000t/a for Plant A, 84,000t/a for Plant B) were great and it had become an important by-product. Coal tar residue, with the yields of 4,500 t/a and 6,400 t/a for Plant A and B, respectively, were always reused for coal blending. The concentration of PAHs with 5-6 aromatic rings was 1.08×10⁴ mg/kg in coal tar residue, the concentration of PAHs in coke discharging smoke & dust (28.81 mg/kg) was relatively low compared with coal tar residue. The ∑BaPeq were 4.2×10³ mg/kg and 0.71 mg/kg for coal tar residue and coke discharging smoke & dust, respectively.
