At the PWRU BPS-2 of Vyngapur field, there is being performed adjustment of APG recovery system

17 May 2018

The Preliminary Water Removal Unit (the BPS-2 area) of Vyngapur field of JSC Gazpromneft-Noyabrskneftegas is 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 a system of automatic drainage) 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.

At the operation site, there are completed erection works. In the course of mounting there were performed installation, alignment and fixing on the foundation, as well as VCS large-scale assembly. There has been mounted air cooler. Also were carried out piping arrangement and laying of power cables.

Currently, there is being performed adjustment of APG recovery system, including VCS. Pre-starting works will be completed with own testing and comprehensive operability verification of equipment as a part of facility.
