Moscow-based gas separation technology company RPC Grasys has supplied the first gas-fired nitrogen compressor station to Chernomorneftegaz, a major Ukrainian oil and gas producer operating in the fields of the Black Sea and Azov Sea.

The compressor station is used for the production of high-pressure nitrogen supplied to the company’s process circuits.

Arranged as two skid-mounted block-boxes, the station capacity is 1,000 cubic meters of 95% nitrogen per hour.

The unique feature of the equipment produced by RPC Grasys is the use of natural gas as a fuel, which helps to significantly reduce customer operating costs and provides a number of benefits in the field conditions.

The company has also recently supplied two mobile nitrogen stations for the independent oil company INK, as part of a new contract.

That equipment will be used in the Yaraktinskoe oil, gas and condensate field, where INK is implementing a natural gas downhole injection project – the first project based on commercial use of the cycling process in Russia.

The mobile nitrogen stations will be used to meet the requirements of the associated petroleum gas collection and transportation process, with the capacity of each nitrogen station for the Yaraktinskoe field at 50 cubic meters of nitrogen per hour, with a purity of 99.5%.
