General information

Inthe process ofmobile nitrogen station operation, product nitrogen purity may beadjusted within abroad range which isaunique feature ofGrasys systems. The air separation nitrogen station isfully automated with norequirement for manned control ofperformance parameters.

The station equipment set includes the compressor with adiesel orelectric drive, air pretreatment unit, gas separation unit and the control system GRASYS intelligent Control-7. Grasys membrane modules, incorporated inthe gas separation unit, donot require special transportation, storage oroperation conditions, even after sustaining low-temperature impacts. This simplifies the operation process and enhances station operating reliability.

Grasys nitrogen stations accommodate all the advantages ofGrasys nitrogen plants and are supplied ready for operation inastandard 20 or40 feet container. Atcustomers request, the station may beprovided inatrailer orskid-mounted version, orasaself-propelled installation.

The use inGrasys nitrogen stations ofthe compressor equipment and control instrumentation ofthe leading European and USproducers and the state-of-the-art intelligent control system, incombination with the perfect design ofthe gas separation unit ensures exceptional reliability ofthe nitrogen station, guaranteed accomplishment ofthe specified technical parameters and ease ofmaintenance. The nitrogen station life cycle exceeds 20 years.
