甲醇制烯烃开工氮气系统存在的问题及改造措施

Problems in start-up system of methanol-to-olefins and process optimization

讨论了甲醇制烯烃工业装置在开工反应器升温过程中存在的氮气消耗量大、能源利用率不高等问题,提出并实施了相应的技术改造措施,降低了装置公用工程消耗,节省了生产运行成本。

The problems that occur during the industrialization of start-up system of methanol-to-olefins, including large consumption of nitrogen, low energy utilization efficiency, etc, are discussed. The optimization solutions are put forward and conducted. The results show that the remarkable effect and considerable economic benefits are achieved. It is of great significance for size selection of nitrogen backup system and reducing the project investment.
