Three membrane nitrogen plants to produce nitrogen from atmospheric air were designed by Gracis. The total plant capacity is 2400 m³ per hour with 99.6% gas purity.

The units were delivered to the Naftan Oil Refinery as part of its large-scale modernization. Currently, a new facility is being built here, adjusted to the needs of the UZK, as well as plants for the production of elementary sulfur by Claus Process.

The product at the new nitrogen plant will be prepared from atmospheric air, which is the main raw material. For the gas separation process a new membrane production technology is used. In this case, only a minimum amount of equipment is needed: an air and gas separation unit and a compressor unit.

This technological solution reduces operating costs, which is advantageous from an economic point of view, and increases the efficiency of the production process.

Three main methods of gas separation are known: adsorption, cryogenic and membrane separation. According to the air, nitrogen and inert gas supply technologist Sergey Senkov, adsorption and cryogenic methods are currently used at the Naftan plant. The membrane method, which requires considerably less energy, will be applied at the plant under construction.

Automatic control system Grasis Intelligent Control will be the core of production units of the plant. Thanks to innovative technologies, only one specialist will be needed to control the production processes.

It is known that the installation is performed by employees of the Volgograd company Neftezavodmontazh. The facility is to be finished in 2020.
