RPC Grasys has performed a turn-key project for Vankorneft CJSC

18 July 2013

As part of the EPCM contract, the research and production company Grasys has completed a turn-key project for Vankorneft CJSC, a Rosneft subsidiary, which included construction of a nitrogen station for the oil treatment and water discharge line (UPSV-Yug). The Vankor oil and gas field is a large-scale project implemented by NC Rosneft and one of the largest projects in Russia today. The field infrastructure includes large industrial facilities, such as the free water knockout unit – one of the largest sites among the field based nitrogen consumers.

RPC Grasys performed the entire package of work for this project: development of the design and detail documentation, engineering, construction, manufacture and delivery of equipment, installation supervision, startup and commissioning.

The Grasys nitrogen station is installed in a separate building and consists of two membrane plants of different capacity. The first plant is designed for continuous nitrogen production with a maximum flowrate of 250 Nm3/hr and a purity of 99%. Structurally, it is configured as the main process line operating at a 100% capacity and the backup line also with a 100% capacity. The second plant is made of three parallel independent lines, each rated for production of 1025 m3/hr of nitrogen with 99% purity. The target production capacity of 2050 m3/hr will be ensured by simultaneous operation of the two lines with the third line in standby. The Grasys nitrogen station for UPSV-Yug was successfully tested under the load and no-load conditions and commissioned.





«The construction site of the nitrogen membrane plant is located in an isolated and remote area and refers to the northern construction climatic zone, which evidently, should have made the Vankor field operations more complex. However, our main and auxiliary equipment is designed to sustain extreme temperatures up to minus 60 °С during transportation and installation», commented Sergey Vladimirovich Potekhin, Director General of RPC Grasys».

The nitrogen produced by the Grasys station is widely utilized in the field for various technological processes, including filtration of formation water, generation of gas blanket in oil tanks, purging of equipment and pipelines. Nitrogen is also used as a backup gas for purging high and low pressure flare headers and for fire suppression at the oil fire heaters.

The Vankor field is the integrated project of Eastern Siberia and Far East development. At the 32nd annual energy conference CERAWeek in Houston held on March 7, 2013, the Rosneft CEO Igor Sechin noted: «Implementation of this project has become possible, in particular, due to the active use of the entire lineup of modern-day technologies». Among them are the membrane and adsorption technologies of RPC Grasys providing various sites in the Vankor field with nitrogen and oxygen.

The Grasys equipment was preferred for a good reason: the company was chosen as the gas separation equipment supplier due to the superior performance characteristics, convenient delivery dates and terms and other objective advantages. No small part in the decision on close cooperation with RPC Grasys was played by the company profound experience (more than 12 years) in the market and successful performance of technically complex projects.

About the Vankor field projects:

The Grasys gas separation plants are used at 5 facilities within the Vankor field: central pumping station (CPS), terminal oil pumping station (TOPS), oil pumping station 1 (OPS1), oil pumping station 2 (OPS2), and the turn-key project on the oil treatment and water discharge line (UPSV-Yug). The nitrogen and oxygen production equipment is also used at the field support base (FSB).
