For the many industries that rely on nitrogen, Korea Energy Industries, Ltd. offers a nitrogen generation system that uses adsorption technology to produce nitrogen gas at low cost. The system employs the PSA method with a high-performance adsorbent, activated carbon molecular sieve (CMS) manufactured by Japan's Kuraray Chemical, to generate nitrogen gas.

Through ongoing system research and development, we have achieved direct separation from ambient air, enabling the production of ultra-pure nitrogen with 99.99% purity.

We will continue to meet our customers' requirements by supplying nitrogen generation systems designed and built with the most suitable configurations and specifications for each application.

Conventional activated carbon cannot separate nitrogen and oxygen from air; however, specially developed activated carbon that selectively adsorbs these gases enables such separation. The process utilizes differences in adsorption rates between nitrogen molecules (4.2×3.0 Å) and oxygen molecules (308×2.8 Å), based on their molecular sizes.

When pressurized air is introduced into an adsorption tower packed with this activated carbon, the smaller oxygen molecules are adsorbed while nitrogen passes through freely. By using two adsorption towers in tandem and alternating between adsorption and desorption cycles, continuous separation of nitrogen and oxygen is achieved. The Pressure Swing Adsorption (PSA) system is a technology that applies this principle to produce high-purity nitrogen or oxygen.

Applications include: semiconductor manufacturing, laser cutting, heat treatment, explosion protection, nitrogen reflow, oxidation prevention, food and pharmaceutical use, equipment supplementation, fresh produce CA storage, rubber processing, and marine use.
