国内成熟的煤焦油蒸馏工艺比较

国内焦化厂成熟的煤焦油蒸馏工艺根据是否加碱可以分为加碱焦油蒸馏工艺和不加碱焦油蒸馏工艺。介绍了4种煤焦油蒸馏工艺,分析了各自的特点。常减压（不加碱）蒸馏工艺市场适应性强、调节灵活、能耗低,炭黑油和沥青钠离子含量低、产品质量高、环保效果好,是大规模焦油加工首选;常压蒸馏工艺流程简单、投资低、操作温度高、能耗高、环保效果差,适合规模较小的简单焦油加工装置。

Comparison of Domestic Mature Coal Tar Distillation Process

The mature coal tar distillation process of domestic coking plant can be divided into alkaline tar distillation process and alkali free tar distillation process. Introduces four kinds of coal tar distillation process, analyzes the respective characteristics of them. Atmospheric and vacuum distillation （alkali free） technology is of market adaptability, flexible adjustment, low energy consumption, low sodion content of carbon black oil and bitumen, high product quality and good effect on environmental protection, so it is the first choice for tar processing of large scale. Atmospheric distillation process is of simple circuit, low investment, high operating temperature, high energy consumption and poor effect of environmental protection, so it is suitable for the small simple tar processing equipment.
