制氮机

Due to its versatility, nitrogen use is becoming increasingly popular in a number of industries including plastic moulding, chemical, food and beverages and packaging. The key benefit of having an industrial nitrogen generator on-site is cost; up to 40% savings can be made when compared to buying nitrogen cylinders.

Our team of engineers can arrange an initial consultation to help determine the recommended solution for your on-site nitrogen requirements. They will then offer professional, practical advice to ensure you are confident in your choice of nitrogen system.

氮气发生器格拉斯顿

哪种氮气发生器适合您?

Dependent on purity, flow rate and a number of other considerations, there are many options when supplying nitrogen. The indicative optimal supply options for nitrogen generators are shown below.

  • 最佳纯度范围:90%至99.0%
  • 最佳流速:1-600Nm³/ h
  • 相对于供应商提供的液体,成本优势:高达50%

Membrane nitrogen separation became commercially available in the early 1980s. It is the most robust of the nitrogen separation technologies. Compared to Pressure Swing Adsorption (PSA) technology, membranes use more energy, but have lower maintenance costs. Membranes are best suited for purities up to approximately 99%, and nitrogen demand of up to around 600 Nm³/hr.

压缩空气中的氧气和氮气被通过中空聚合物纤维侧壁的相对渗透速度所隔开。氧分子比氮分子穿过纤维的渗透速度更快,从而使其有选择地被耗尽。氮气纯度随着气流沿纤维向下流动而增加。根据在膜中的停留时间,可以获得高于99.99%的氮气纯度。如果您需要更高的纯度,其他分离技术将更具成本效益。

  • 范围纯度:99%至99.995%
  • 流量:1-1000Nm³/ h
  • 相对于供应商提供的液体,成本优势:高达50%

变压吸附(PSA)对于现场生成高纯度高于99%(可能高达99.995%的纯度)的氮气是具有成本效益的,而在高能耗地区则可降低纯度至97%的纯度。空气通过在碳分子筛(CMS)床上压缩而分离,该床优先吸附氧气。同时,在CMS的第二个转鼓中,压力降低,因此释放出所吸收的氧气。现在已经剥夺了氧气的CMS床再次准备好进行进一步的吸附压缩循环。
