Nitrogen Generator System

Beside the Air Compressors and Dryer Skid and Dryer Skid, CSI is in the unique position to supply both offshore and onshore facilities for Nitrogen Generator Systems. We are capable to provide proven customised systems for different pressure flow and size to meet all the third party and custom requirements.

CSI will provide the air separation technology in the form of:

  1. PSA (Pressure Swing Absorption)
  2. Nitrogen Membrane Technology

PSA (Pressure Swing Adsorption)

Using the Carbon Molecular Sieve (CMS) technology, the PSA system is able to produce high purity nitrogen from air of up to 99.9995% purity which membrane systems are unable to provide. Although cryogenic systems are able to produce such high purity levels as well they are considerable more complex and justified only by large consumption volumes.

Nitrogen Booster Compressor:

CSI provides custom built Nitrogen Booster Compressor to boost up N2 pressure for facility usage for filling of nitrogen bottles for backup. Options of oil free or oil injected booster compressors are available to boost up N2 pressure till 200BAR or more. N2 bottle racks for filling are also available as part of our offer.
By substituting out of date air separation plants, nitrogen production savings largely exceed by 50%. The net cost of nitrogen produced by nitrogen generators is 20-30 times less that the cost of bottled or liquefied nitrogen.
