OREANDA-NEWS. June 7, 2008. Pursuant to the contract made, CJSC GRASYS has supplied to OJSC Prokopyevskugol a mobile nitrogen station in the MA series. The supplied nitrogen station is designated for mine inerting upon depletion. The mobile nitrogen station will be used at the “Krasnaya Gorka” mine (Kemerovo region) and is rated to produce 280 nmі/hr of 99% nitrogen.

GRASYS nitrogen stations in the MA series are light-weighted, fully automated and mobile. Nitrogen stations incorporate the most advanced membrane technology of air separation. This helps GRASYS make its stations both compact (all station equipment is installed on a single platform in a standard container) and high-capacity without sacrificing their reliability, ease of maintenance and operation.

Stations are installed in a heated container which allows their operation in various climatic zones, including regions with cold and moderate microclimate. Mobile nitrogen stations may be provided truck-mounted for transportation to any required work site.

The equipment manufactured by GRASYS for inert environment generation and gaseous nitrogen production is applied for explosion and fire safety assurance by mines suspension and hydrocarbons transportation, transshipment and storage, as well as for pipelines testing and purging and process vessels cleaning from accumulated explosive gases.

Today, GRASYS is one of the largest and most reputable companies in the field of gas separation. GRASYS is also one of the world leading manufacturers of membrane and adsorption plants for nitrogen and oxygen production, hydrogen concentration, gas mix control, etc.
