packaging, inerting and blanketing-wepoker官网

inerting, also known as blanketing, is the process of replacing the atmospheric air around a substance or material with a non-reactive gas, such as nitrogen or argon, to ensure it stays in a passive or unreactive state.

nitrogen is typically used due to its inertness and friendly environmental profile making it suitable for a host of applications. since it does not react with most materials, nitrogen is an excellent inerting, blanketing and purging gas that can be used to protect valuable chemical products from harmful contaminants. one of its most important uses is to eliminate flammability risks in reactor vessels and storage tanks.

other gases such as carbon dioxide and argon can also be used in some cases for inerting purposes.

we can help you choose the optimum method to meet your needs, while also keeping gas usage to a minimum.

受控临界氧气浓度（coc）水平：用于计算混合物可燃性和 coc 的专有软件
质量：延长保质期，防止空气和其他污染物渗透并造成降解
纯度范围和供气模式选择：根据您对纯度、使用模式、体积及占地面积的用气要求，我们为您推荐最高效的供应方式

氮封系统

连续吹扫覆盖

氮气或其他惰性气体连续注入用于保持储罐顶部空间内的安全氧气浓度。

压力控制氮封

氮气被引入储罐顶部空间以保持设定压力。与连续吹扫相比，氮气加压能最大限度地减少进气泄漏，并能减少氮气用量。

concentration control blanketing

an oxygen monitoring system controls the flow of nitrogen into the headspace of the tank. a concentration control system can help enable precise operation and reduce gas usage compared to continuous purging.

氮气吹扫系统

这种方法通常在被吹扫容器只有一个开口的情况下使用，或者在吹扫环氧乙烷消毒器等批量操作中使用。氮气用于为容器或者管道加压，它混合并稀释原有气体，并将其排出到排放物控制单元。不断重复该过程，直至容器被充分吹扫。

稀释液吹扫和干燥

氮气持续的通入容器，稀释混合气，然后通过出口（最好是进口的对面）排出。容器的形状以及进口和出口的方向是影响稀释吹扫效率的重要因素。干燥过程与之类似，但可去除残留材料。

displacement purging and pigging

nitrogen can be used to purge out a pipe run. a “pig,” a bullet shaped object, can also be pushed through the line using nitrogen gas pressure in order to purge the contents.
