Abstract:

Overflowing of dephenolized naphthalene oil tank is introduced in production replacing the tank standing method,which can reduce the phenolate content in feedstock of dephenolized naphthalene oil and improve the stability of technical naphthalene plant.The optimization of operating parameters for the technical naphthalene plant can also minimize energy consumption,finding a reduction down to 87.26m3/t in COG consumption and saving energy cost by about 0.64 million yuan per year.
