Oil degassing buffer BDN


Oil degassing buffer (BDN) are used at oilfield facilities, oil and gas production facilities, oil treatment plants and preliminary water discharge units.

Functions of BDN Oil degassing buffer

  • oil degassing
  • treated oilfield water discharge
  • associated petroleum gas production
  • preliminary treated oil products for further processing production
  • increase in producing capacity of oil treatment plants
  • improving the properties of petroleum products for its subsequent transportation

Design of BDN degassing drum

The housing is a horizontal cylindrical vessel, which provides simultaneous discharge of degassed oil, oilfield water and associated petroleum gas. They are installed aboveground. They are assembled on the leg-supports or lug-supports.

The Saratov Reservoir Plant also manufactures modular packaged (skid-mounted) configuration of degassing vessels: the container and primary piping are placed in a heat-insulated block-module made of sandwich panels. This design protects the equipment from unauthorized access inside. It is possible to install on a metal frame, which greatly simplifies installation and allows to transport the equipment as needed on various production lines.

The oil degassing buffers BDN provide hatches, pipes and fittings which serve to:

  • primary oil emulsion loading
  • the outlet of preliminary treated oil
  • treated water outlet
  • gas outlet
  • additional equipment installation (instrumentation and controls, shutoff and safety valves)

There are the baffles with devices for the degassed and dehydrated oil collecting and liquid droplets capturing.

At the Customer's request, heat insulation of the housing is provided to maintain the operating temperature.

Degassing buffers BDN can be completed with a ladder and a service platform which provide service personnel access to hatches.

Design calculation (volume, dimensions, location and diameter of hatches and fittings, etc.) is performed individually based on pressure requirements, degree of oil refining, processing capacity and other parameters.

Technical characteristics of oil degassing vessels

  • volume-from 12 m3 to 200 m3
  • liquid capacity-500-8000 m3/day
  • pressure - 0.6-1.0 MPa
  • gas production rate - up to 100 Nm3/t

Oil degassing buffers BDN manufacture at the Saratov Reservoir Plant

Our Plant has the necessary Certificates of conformity for the manufacture of oil and gas tanks and separators.

We manufacture degassing drum in accordance with the applicable state standards on high-tech equipment, which guarantees the quality of the supplied units and trouble-free operation throughout its service life.

Only steel grades that are capable of withstanding severe operating conditions (corrosion behavior of the aggressive working product) are used for the manufacture.

Special attention is paid to surface preparation to sandblasting and anticorrosive protection of internal and external surfaces.

While manufacturing, automatic or manual weld inspection, leakage tests and high-pressure tests are carried out.

All performed works are reflected in final completion protocols and the Product certificate.

Summary tables of technical characteristics of oil and gas separators and sedimentation tanks can be found here.
