The Preliminary Water Removal Unit (PWRU), located at the area of Booster Pumping Station No. 2 (BPS-2) of Vyngapur field of JSC Gazpromneft-Noyabrskneftegaz, is being equipped with a system for recovery of associated petroleum gas of low oil separation stages.

The basis of this system is a vacuum compressor station (VCS), supplied by ENERGAS. VCS is designed to compress low-pressure (0.001 MPa) APG of the end stage and its feeding, after combining with gas of the first separation stage, to the existing main compressor station.

Vacuum CS is made on the basis of oil-filled screw-type compressor. The gas treatment at the compressor inlet is performed by a highly efficient two-stage filter scrubber with an automatic drainage system integrated in the process unit's block-module.

The rated capacity of the unit is 1,500 m3 / h, gas flow is controlled by a special two-level control system.

The equipment is designed taking into account extreme operating conditions (minimum air temperature - minus 59°C, average temperature of the coldest five-day period - minus 50.5°C). VCS is housed in its own all-weather shelter, equipped with all necessary life support and safety systems and will operate in an automatic mode. Local ACS is integrated with the upper level of APCS of BPS-2.

The whole cycle of pre-starting works will be performed by the technical specialists of ServicENERGAS.

Previously, ENERGAS Group supplied and commissioned vacuum compressor stations at a number of facilities of JSC Gazpromneft-NNG. This is BPS-1 and Central Production Facilities (CPF) of BPS-3 of Vyngapur field, Oil Processing and Pumping Shops (OPPS) of Vyngayakha and BPS-2 of the Ety-Pur field (pictured below).

REFERENCE. Vyngapur oil and gas condensate field is located in the Purovskoye District of the Yamal-Nenets Autonomous Area. It was discovered in 1968 and has been in commercial development since 1982. It has a well-developed infrastructure. It is one of the largest fields of JSC Gazpromneft-Noyabrskneftegaz and along with Sporyshevskoye, Kholmogorskoye and Chatylkinskoye fields provides the bulk of the company's production.

Gazpromneft-Noyabrskneftegaz is engaged in oil and gas production activities in the Yamal-Nenets and Khanty-Mansi Autonomous Areas. Since the establishment of the enterprise, more than 850 million tons of hydrocarbons in oil equivalent have been extracted. Taking into account the branch of Gazpromneft-Muravlenko, the company develops 28 fields.
