Oil dehydration vessels BON


Oil dehydration vessel BON is used as a sump for dehydration and desalting of oil products as a part of oil treatment plants and preliminary water discharge units. Their application speeds up the process of separation of the oil emulsion, which allows to increase the producing capacity.

The Saratov Reservoir Plant manufactures vessels BON in three versions:

  • BON-P for preliminary dehydration
  • BON-G is for deep dehydration
  • BON-S for desalination

Main functions

  • partial dewatering with a small amount of residual gas in BON-P vessels
  • deep dehydration in BON-G vessels
  • the process of desalting in BON-S vessels
  • preliminary treatment of discharged water

Oil dehydration vessel BON configuration

They have a horizontal cylindrical housing with elliptical heads. They are mounted only aboveground on leg-supports or lug-supports Our Plant offers installation of equipment on a metal frame, which makes it easy to transport and makes it portable. We also supply modular oil dehydration vessels BON in a heat-insulated block-box, which protects against unauthorized access and allows to install other oilfield equipment inside (such as pumps, mixers, etc.).

There are hatches, pipes and fittings in the housing, through which the filling takes place, the output of the resulting liquids and installation of process equipment. At the Customer's request, it is possible to fully automate the process through the use of control and measurement instrumentation.

The principle of action of the BON vessels s is to separate the input emulsified crude oil into water, mechanical impurities and oil under the action of centrifugal forces: drops of liquid are formed into a foil, which is displayed as a continuous flow of liquid.

In addition, it is possible to supply the ladder and service platform, as well as thermal insulation to maintain the operating temperature.

Precise construction and arrangement of the vessels BON depend on the individual Customer requirements (pressure, capacity, properties of the feedstock and the characteristics of the resulting fractions).

Manufacturing of oil dehydration vessels BON (dehydration tanks, apparatuses)

Our Plant has all the necessary Certificates of conformity for the manufacturing of oil and gas separators and sedimentation tanks.

The manufacture is carried out according to the individual order, because of: a) the producing reserves at the oil and gas production enterprises have different physico-chemical properties, b) the equipment can be inserted into various places of a technological line.

The vessels are made of high-resistant steel grades, which are less susceptible to corrosion and high aggressiveness of the working product. The metal for production should also withstand high operating pressure.

The manufacturing process consists in the workpieces manufacture for shells, heads, supports, hatches. Further, the main and auxiliary elements are welded by automatic or manual welding into a single structure. All seams undergo weld inspection. The finished product shall also undergo leak testing and high-pressure test. The tests carried out are necessary to ensure trouble-free operation of the equipment. Prior to application of corrosion preventive compounds on the inner and outer surfaces is sandblasting.

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