Methods and systems for producing vinyl acetate may use a flammable limit (FL) formula with improved efficiency at more than one location of the vinyl acetate production process. Wherein the FL may be used at one or more of the four parts of a vinyl acetate production process: a reactor, an inter-process heat exchanger, a carbon dioxide removal system, and an ethylene recovery system. This FL is a function of operating conditions and includes at least one interaction item that represents a correlation of two or more operating conditions (e.g., temperature, pressure, and component concentration) on the FL. 生产乙酸乙烯酯的方法和系统可以使用可燃极限(FL)公式，其在乙酸乙烯酯生产方法的多于一个位置处具有改进的效率。其中，FL可以用于乙酸乙烯酯生产方法的四个部分的一个或多个处：反应器，过程间的热交换器，二氧化碳除去系统，和乙烯回收系统。这种FL是操作条件的函数，并且包括至少一个相互作用项目，其代表在FL上的两种或更多种的操作条件(例如温度、压力和组分浓度)的相互关系。
