Grasys has revealed it is to undertake supply of three mobile nitrogen stations for LLC Gazprom transgaz Samara, a subsidiary of OJSC Gazprom.

The stations supplied are designated for equipment purging and fire safety assurance at compressor stations operated by LLC Gazprom transgaz Samara.

All three stations are installed on Ural vehicle, thus allowing prompt nitrogen delivery for repair works at the customer’s compressor stations.

The stations combine the benefits of compact design and high capacity, with reliability, serviceability and simplicity of operation. The wide temperature range of the compressor stations operates between −50°С and 50°С.

Characterised by exceptional reliability of operation in the Far North and Siberia regions, the mobile nitrogen stations from Grasys were thought to have been recommended for production and adoption at all OJSC Gazprom facilities.

Specifically, the MA nitrogen stations are suited for use at compressor stations, booster compressor stations, underground gas storage facilities at compressor stations for pipelines purging and pressure testing, impulse gas generation, temporary abandonment and other applications.

The discussed stations are designed for production of 98% gaseous nitrogen from atmospheric air, at a rate of 150 nm³/hr. During operation, nitrogen purity may easily be adjusted to ensure maximum cost-efficiency.
