随着中东大量低价进口甲醇的进入,国内许多企业开始考虑以进口甲醇生产烯烃。进口甲醇生产烯烃,可以减小烯烃项目总投资规模,节约国内资源,同时也减少了CO2排放。进口甲醇制烯烃项目的竞争力,很大程度上是由甲醇进口价格决定的。本文根据近年来甲醇、石脑油进口价格情况,对甲醇制烯烃(MTO)和石脑油制烯烃两种工艺的生产成本进行测算和比较,由此建议,如果能获得较低价格的进口甲醇,在目前国内政策允许的情况下,可以考虑通过进口甲醇生产烯烃;或在煤炭产地以较低的煤价,建设甲醇、烯烃及下游产品一体化的烯烃项目。
With the Middle East imported a large number of low-cost methanol imports, many domestic enterprises began to consider the import of methanol to produce olefins. The import of methanol to produce olefins can reduce the total investment scale of olefin projects, save domestic resources and at the same time reduce CO2 emissions. The competitiveness of imported methanol to olefins projects is largely determined by the import price of methanol. Based on the import prices of methanol and naphtha in recent years, this paper estimates and compares the production costs of MTO and naphtha olefins. Therefore, it is suggested that if the import methanol with lower price can be obtained, , With the current domestic policy permitting, consider the production of olefins through the import of methanol; or the construction of integrated olefins for methanol, olefins and downstream products at coal prices at a lower coal price.
