Modular (Containerized) nitrogen generators in Moscow

Modular (Containerized) Nitrogen Generators

High-tech modular (containerized) generators are designed to recover nitrogen from atmospheric air using membrane or adsorption technology. The equipment of the category consists of a single containerised module containing all the necessary components. Nitrogen generation plants can vary in size, production capacity, gaseous product purity and discharge pressure.

Modular Nitrogen Generators Specifications

Modular nitrogen generators can vary in size, production capacity, gaseous product purity, and discharge pressure. In other respects, the equipment package is standardised and characterised by common specifications. The plant standardised module consists of the following key items:

A compressor to compress the incoming atmospheric air;

A filtration system;

A gas separation unit to produce nitrogen with a purity of up to 99.9995%;

Receivers, etc.

Automatic ventilation, heating, fire suppression, interior and emergency lighting systems, etc., are installed inside the modular nitrogen generation plant. The entire package ensures reliable, trouble-free and long-lasting operation of the plant. Depending on the purpose of the plant and the customer's requirements, Grasys can supply membrane or adsorption type plants with a capacity of up to 3,000 m³/h and a nitrogen purity of up to 99.9995%.

Benefits of Modular Units

Grasys works with leading component suppliers to ensure that its nitrogen and other gas separation plants are robust and long-lasting. We offer tailor-made design and high-quality warranty and maintenance services.

Modular (containerized) nitrogen generators offer many advantages. They are:

Mobile. The unit can be easily transported to any job site, which is particularly convenient within the confines of large enterprises.

Independent of weather conditions. The compact systems are designed to operate at extreme low and high temperatures from –45 °C to +40 °C.

Ready for use. The plant just needs to be plugged in and it is ready to produce gas.

Fully automated and autonomous, requiring no operator presence or intervention.

The economic benefits and low operating costs ensure a low cost of the nitrogen produced.

The system can be started up and shut down quickly.

The plant is relatively compact in size and light in weight.

Reliable and safe long-term continuous operation.

Tailor-made plant design for each customer, with the option of membrane or adsorption technology, taking into account all the specifics and operating conditions as well as the requirements for gas purity and flow rates.

The purchase of a modular (containerized) nitrogen generator is a worthwhile investment in the development and modernisation of any production facility using gaseous nitrogen. Grasys units have an excellent track record in the largest industrial and mining companies in Russia and the CIS.

General Description

Grasys manufactures air mixture separation units based on the latest scientific advances in membrane and adsorption gas separation. A key advantage of Grasys membrane nitrogen generation systems used in modular nitrogen generation plants is their high reliability, unpretentious operation and ease of maintenance.

The plants are recommended by the State Technical and Mining Inspectorate (Gosgortechnadzor) for drilling, development, repair and operation of gas and oil wells, exposure of product formations, repair and operation of pipelines and reservoirs.

Modular (containerized) nitrogen generators combine all the advantages of the Grasys nitrogen generation units and are supplied fully operational in a standard 20ft or 40ft container. On request, the plant can be supplied in a custom-sized containerised module, or in a trailer-mounted, skid-mounted or self-propelled version.

The use of compressor equipment and instrumentation from leading European and US manufacturers, an advanced smart monitoring and control system and the perfect design of the gas separation unit ensure exceptional reliability, guaranteed performance and serviceability of Grasys nitrogen generation plants. The nitrogen plant has an operating life of more than 20 years.
