制氮機廠(chǎng)家提取氮氣的方式是怎樣的？

通常情況下制氮機制取氮氣里面含氮量小于0.5%時(shí),是可以用脫氮劑直接除氮,要是含氮量在0.5-3%時(shí),應該用催化劑加氫以此達到除氮。目的，正常的情況下含氮大于3%是采用分級催化除氮。主要是因為氮氣里面含氮量過(guò)高,這個(gè)時(shí)候是可以按化學(xué)計量能所需要的氫氣含量。要是一次性使用制氮機加入,是會(huì )發(fā)生的危險，而且還會(huì )產(chǎn)生出比較大的熱量,也容易燒壞催化劑。

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.

這個(gè)時(shí)候一定要嚴格控制好加氫的份量，這個(gè)時(shí)候可以進(jìn)行分級除氮。要是原料氮氣中的含氮量過(guò)高,是可以用部分純氮對原料氣進(jìn)行稀釋?zhuān)@個(gè)時(shí)候混合氣體里面的含氮量在小于3%以后再進(jìn)行加氫催化除氮。

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.

采用脫氮劑清除雜質(zhì)氮的典型工藝流程:氮氣經(jīng)催化除氮器{除去氮)、水冷卻器和吸附干燥器(除去水汽)、氣體過(guò)濾器(除去塵埃顆粒)后,即得純氮產(chǎn)品。采用加氫催化除氮的典型工藝流程:首先在氮氣中加適量氫氣(添加量為氮氣中含氮量的二二倍以上) ,然后通過(guò)催化除氮器(除去氮)、水冷卻器和吸附于燥器(除去水汽)、氣體過(guò)濾器(除去塵埃粒)后,即得純氮產(chǎn)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).

當氮氣中含氮量較大(大于39%) ,可采用分級加氫催化除氮工藝,氮氣在催化除氮器前，需要嚴 格控制加氫量,通過(guò)催化除氮器1(- -次除氮) ,再加入少量氫氣催化除氮器2進(jìn)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.

當原料氮氣里面含有氮比較高,這個(gè)時(shí)候純氮是不允許有過(guò)量氫氣存在。這個(gè)時(shí)候制氮機氮氣純化裝置用得就是先加氫催化再進(jìn)行除氮,活性氮化銅除氫方法純化氮氣的工藝流程是在原料氮氣里面根據氮的含量,往里面添加一些過(guò)量的氫以后，再通過(guò)制氮機進(jìn)行除氮,后用電加熱器以及氮化反應把氮氣中的過(guò)氫除去。

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.
