| titleOfInvention | Method and device for continuously rectifying and separating medium/low-temperature coal tar crude phenols |
| abstract | The invention discloses a method and device for continuously rectifying and separating medium/low-temperature coal tar crude phenols. The method is implemented in a way that: crude phenols extracted from medium/low-temperature coal tar as raw materials are subjected to six-tower continuous rectification to effectively perform impurity removal and separation, thereby obtaining a mixed phenol product containing phenol and orthocresol of which the purities are higher than 99.5% and 2,6-dimethylphenol, 4-methylphenol, 3-methylphenol and 2-methylphenol of which the contents are higher than 99%, a mixed phenol product containing 2,4-dimethylphenol, 2,5-dimethylphenol, 4-methyl-2-ethylphenol and 6-methyl-2-ethylphenol of which the contents are higher than 96%, and the like. The device comprises a light component removal unit, a phenol-orthocresol unit, a meta-paracresol unit, a dimethyl phenol unit a trimethyl phenol unit, a decolorization unit and a vacuum system which are connected through pipelines. In view of the composition characteristics of medium/low-temperature coal tar crude phenols, the invention obtains optimized technique and parameters for separating phenol products; and the whole technical process is reasonable and continuous, has the characteristics of low energy consumption, high product quality, high stability, low production cost and the like, and thus, is an efficient and feasible continuous technique for continuously rectifying and separating medium/low-temperature coal tar crude phenols. |
