摘要
实现煤化工可持续健康发展的重要因素就是高效处理其过程中产生的废物,本文对煤化工过程中产生的气化废渣处理形式及其主要组分进行了介绍,详细分析了甲醇制烯烃工艺流程中废黄油与废碱液的产生机理,并对湿式空气氧化法、焚烧法这两种处理废碱液的方法进行了阐述。因为黄油大量存在于废碱液中,所以减少废黄油的产生量,不仅能够减轻其处理量,也在一定程度上使废碱液的处理难度得到缓解。
The important factor to realize the sustainable and healthy development of coal chemical industry is the efficient treatment of the waste generated in its process,This paper introduces the treatment forms and main components of gasification waste residue produced in coal chemical process.the mechanism of producing waste butter and waste alkali liquor in the process of producing olefin from methanol is analyzed detailedly,and the two methods of treating waste alkali liquor,namely wet air oxidation and incineration,are expounded.Because butter exists in a large amount of waste lye,reducing the production of waste butter can not only reduce its processing capacity,but also alleviate the difficulty of treating waste lye to some extent.
