具有在先净化和冲洗步骤的用于封装NO/N2混合物的方法
摘要：
本发明涉及一种用于将气态NO/N2混合物封装在至少一个容器内的方法，其特征在于，在允许所述NO/N2混合物进入前，所述至少一个容器至少经历净化步骤、排泄步骤和气体冲洗步骤，在所述净化步骤期间，将容器的内部容积置于与环境大气流体连通，在所述排泄步骤期间，将容器的内部容积置于低压下，在所述气体冲洗步骤期间，允许惰性气体进入所述至少一个容器。优选而言，最终气态NO/N2混合物在介于P1与800巴之间的压力下包含小于或等于1200ppm（体积）的NO含量。
摘要（英）：

The invention relates to a method for packaging a gaseous NO/N2 mixture into at least one container which is characterized in that, prior to admitting the said NO/N2 mixture, said at least one container is subjected to at least a purging step during which the internal volume of the container is placed in fluidic communication with the ambient atmosphere, an evacuating step during which the internal volume of the container is placed under depression, and a gas rinsing step during which an inert gas is admitted to said at least one container. For preference, the final gaseous NO/N2 mixture contains an NO content less than or equal to 1200 ppm by volume for a pressure of between P1 and 800 bar.
