| Abstract: | Jinan Steel developed and applied negative pressure distillation technology for the new-built crude benzene distillation system,which is making the medium under normal pressure fractionation in vacuum tower and decreasing its distillation boiling point,at the same time,supplying heat with heat circulation oil.Applying the negative pressure distillation technology saved steam volume 35 thousand tons every year,saved coke oven gas by 280 m3/h;reduced the emission of benzene hydrocarbon by 15.3 thousand cubic ... |
