热解油中提取苯乙酮的工艺设计及模拟

Process Design and Simulation of Extraction of Acetophenone From Pyrolysis Oil

热解处理生活垃圾产生的热解油中含有丰富的有机物,对热解油中的物质进行资源回收具有很大的经济价值和环保意义。设计了多塔精馏提取热解油中苯乙酮的工艺方法,运用Aspen Plus软件进行了工艺模拟,建立了比较准确的系统模型,实现了物料平衡。通过变压精馏的方式,实现了苯酚和苯乙酮共沸物的高纯度分离,为工业放大提供了的理论依据和数据支持。

The pyrolytic tar produced in the process of garbage pyrolysis treatment,is rich in organic matter,so the recovery of resources in pyrolysis oil has great economic value and environmental significance.In this paper,a multi column distillation process for the extraction of acetophenone from pyrolytic tar was designed.Aspen Plus software was used to establish an accurate system model to realize material balance.The high purity separation of phenol and acetophenone provides the theoretical basis and data support for industrial amplification.
