Abstract:

Based on the industrial metabolic analysis on chlorine element in the process of polyurethane intermediate production，a thought of chlorine recycle was proposed，in which chloride was obtained by catalytic oxidation of hydrogen chloride. An eco-industry mode of chlorine recycle，salinity wastewater，phosgene and other by-products in the process of polyurethane intermediate production was mapped out by applying the principles of system engineering and eco-industry. The industrial metabolic situation of chlorine element in this mode was analyzed. The implementation of the eco-industry mode is put forward at the end of this paper.

摘要：

以聚氨酯中间体生产过程为研究对象，运用工业代谢方法，在对传统聚氨酯中间体生产过程中氯元素的工业代谢分析的基础上，提出通过氯化氢催化氧化制氯技术实现氯元素循环利用的思想；综合过程中含盐废水以及光气回收的资源化利用和其它副产物的处理，应用生态工业和系统工程原理，提出聚氨酯中间体生产过程氯循环利用的生态工业模式，并分析了该模式中氯元素的工业代谢情况，提出了该生态工业模式的实施方案。
