Separation and refining
The separation and refining of dibenzofuran can use heavy wash oil as the raw material, using 60 float valve tray distillation towers to cut the wide fraction of dibenzofuran at 280~286℃, and the content of fluorene is 55%~65%. The wide fraction is then rectified in the rectification tower with Nt=40 to cut the narrow fraction of dibenzofuran, and its content of dibenzofuran can reach 80%.
