OREANDA-NEWS. July 10, 2008. GRASYS is to supply to CJSC Vankorneft four large nitrogen plants with the total capacity of more than 4,500 nm³/hr of 99% nitrogen, with the largest one capable of producing nitrogen at the rate of 300 nm³/hr. The nitrogen plants will be used at the site for the assurance of explosion and fire safety and ensuring compliance with process requirements.

The supply is to be effected under the contract entered into with CJSC Vankorneft, a subsidiary of OJSC NK Rosneft, for the development and manufacture of several membrane and adsorption nitrogen plants designated for use in the Vankorskoye field. The equipment of this class has never been previously made in Russia and CIS.


As part of the project, one of the world largest adsorption nitrogen plants rated to 6,600 nm³/hr is also to be supplied. As agreed upon with the customer, the adsorption nitrogen plant will consist of two parallel lines and will produce nitrogen with two different purity parameters. At the 99% purity level, the capacity will be 6,600 nm³/h, and at 99.98% — 2,000 nm³/ч. Nitrogen pressure will be 5 atm. The designed plant will be extremely simple in operation and will require no constant control due to its full automation.

GRASYS has won the tender held by CJSC Vankorneft for the supply of equipment for inerting process tanks for oil and Vankor intermediate water. The tender was held in March, 2007.

The Vankorskoye field is a large capital project and one of the main projects of OJSC NK Rosneft. The cost of the Vankor design project is estimated at \\$6 billion, and the expected oil production rate is ca. 25 million tons per year.

GRASYS was awarded the contract in view of the best technical and performance characteristic of its equipment, delivery conditions and schedule as well as due to other objective advantages. The extensive market experience accumulated by GRASYS and the successful performance of technically complex projects also played an important role.

Strengthening its presence in the international market, GRASYS is currently 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.
