SEPARATION OF AROMATIC HYDROCARBONS FROM PETROLEUM FRACTIONS |
| 摘要 |
An improvement to a continuous solvent extraction-steam-distillation process for the recovery of aromatic hydrocarbons in the range of C6-C16 from a feed stream containing such aromatics and aliphatic hydrocarbons in the range of C5-C16 which resides in using two extractive distillation zones thermally linked to recover heat and solvent, thereby resulting in a heat savings. |
