制氮机厂家提取氮气的方式是怎样的？

通常情况下制氮机制取氮气里面含氮量小于0.5%时,是可以用脱氮剂直接除氮,要是含氮量在0.5-3%时,应该用催化剂加氢以此达到除氮。目的，正常的情况下含氮大于3%是采用分级催化除氮。主要是因为氮气里面含氮量过高,这个时候是可以按化学计量能所需要的氢气含量。要是一次性使用制氮机加入,是会发生的危险，而且还会产生出比较大的热量,也容易烧坏催化剂。

Under normal circumstances, when the nitrogen content in nitrogen is less than 0.5%, denitrogenation agent can be used to remove nitrogen directly. If the nitrogen content is 0.5-3%, catalyst hydrogenation should be used to remove nitrogen. Objective: under normal circumstances, the nitrogen content of more than 3% is to use staged catalytic nitrogen removal. The main reason is that the nitrogen content in nitrogen is too high. At this time, the hydrogen content required by stoichiometric energy can be calculated. If the disposable nitrogen generator is added, it will be dangerous, and it will generate relatively large heat, and it is easy to burn the catalyst.

这个时候一定要严格控制好加氢的份量，这个时候可以进行分级除氮。要是原料氮气中的含氮量过高,是可以用部分纯氮对原料气进行稀释，这个时候混合气体里面的含氮量在小于3%以后再进行加氢催化除氮。

At this time, the amount of hydrogenation must be strictly controlled, and the nitrogen can be removed by stages. If the nitrogen content in the feed gas is too high, part of the pure nitrogen can be used to dilute the feed gas. At this time, when the nitrogen content in the mixed gas is less than 3%, the nitrogen can be removed by hydrogenation catalysis.

采用脱氮剂杂质氮的典型工艺流程:氮气经催化除氮器{除去氮)、水冷却器和吸附干燥器(除去水汽)、气体过滤器(除去尘埃颗粒)后,即得纯氮产品。采用加氢催化除氮的典型工艺流程:在氮气中加适量氢气(添加量为氮气中含氮量的二二倍以上) ,然后通过催化除氮器(除去氮)、水冷却器和吸附于燥器(除去水汽)、气体过滤器(除去尘埃粒)后,即得纯氮产品。

The typical process of removing impurity nitrogen with denitrifier is as follows: nitrogen is removed by catalytic denitrifier, water cooler and adsorption dryer (water vapor is removed), and gas filter (dust particles are removed) to obtain pure nitrogen product. The typical process flow of hydrocatalytic nitrogen removal is adopted: firstly, appropriate amount of hydrogen is added into nitrogen (the amount is more than twice of the nitrogen content in nitrogen), and then pure nitrogen product is obtained through catalytic nitrogen remover (nitrogen removal), water cooler and adsorption in dryer (water vapor removal) and gas filter (dust removal).

当氮气中含氮量较大(大于39%) ,可采用分级加氢催化除氮工艺,氮气在催化除氮器前，需要严 格控制加氢量,通过催化除氮器1(- -次除氮) ,再加入少量氢气催化除氮器2进行二次除氮。

When the nitrogen content in nitrogen is large (more than 39%), the staged hydrogenation catalytic nitrogen removal process can be used. Before the catalytic nitrogen remover, the hydrogenation amount of nitrogen needs to be strictly controlled. The secondary nitrogen removal is carried out by catalytic nitrogen remover 1 (- - secondary nitrogen removal) and a small amount of hydrogen is added to catalytic nitrogen remover 2.

当原料氮气里面含有氮比较高,这个时候纯氮是不允许有过量氢气存在。这个时候制氮机氮气纯化装置用得就是先加氢催化再进行除氮,活性氮化铜除氢方法纯化氮气的工艺流程是在原料氮气里面根据氮的含量,往里面添加一些过量的氢以后，再通过制氮机进行除氮,后用电加热器以及氮化反应把氮气中的过氢除去。

When the nitrogen content in the feed nitrogen is relatively high, excess hydrogen is not allowed to exist in the pure nitrogen. At this time, the nitrogen purification device of nitrogen generator uses hydrogenation catalysis first and then nitrogen removal. The process flow of active copper nitride dehydrogenation method to purify nitrogen is to add some excess hydrogen into the raw nitrogen according to the nitrogen content, then remove the nitrogen through the nitrogen generator, and then remove the hydrogen in the nitrogen by electric heater and nitriding reaction.
