褐煤制聚丙烯和低阶烟煤制聚丙烯的经济性比较研究

Economic comparison of lignite and low rank bituminous coal to polypropylene

根据目前已公布的技术经济数据进行推算,对褐煤制聚丙烯项目和低阶烟煤制聚丙烯项目的经济性进行了分析和比较,并对褐煤制聚丙烯面临的技术风险进行了分析,结果表明,褐煤制聚丙烯项目的各项经济指标和低阶烟煤制聚丙烯项目相差不大,但是褐煤气化技术将面临巨大的技术风险。因此,在没有特别明显的经济性优势的情况下,选择以褐煤为原料生产聚丙烯并不合适;在拥有自有煤矿并实现煤炭就地转化的基础上,选择低阶烟煤为原料生产聚丙烯无论在经济性上还是技术上都更具有可行性。

According to the currently published technical and economic data, the economy of lignite to polypropylene project and low rank bituminous coal to polypropylene is analyzed and compared. The technical risk of lignite to polypropylene is analyzed. The results show that there is only very slight difference of economic indicators between lignite to polypropylene project and low rank bituminous coal to polypropylene. However, lignite gasification technology will face a huge technical risk. Therefore, in the case of absence of special obvious economic advantage, it is not appropriate to choose lignit as raw material to produce polypropylene. Based on possessing coal mine and realizing local transforming of coal, choosing low rank bituminous coal as raw material to produce polypropylene is more feasible in economy and technology.
