DEHYDRATION OF OIL – ООО "ХИММАШ-АППАРАТ"

LLC “Himmash apparat” offers to supply equipment for dehydration and desalting: electrical dehydrators, oil and water sumps, oil gas separators, heat exchangers, degassing units, etc.
In the design of electrical dehydrators offered by LLC ” HIMMASH-APPARAT” has been produced before operating experience of equipment, improved installation and operation conditions, can be manufactured in horizontal and vertical versions.

The design of electrical dehydrators include: fitting to accommodate the devices to control the water level, oil pressure and temperature. Completeness of delivery defined by the customer, based on the capabilities of its design organization and procurers. The basic package includes always economical, high-voltage power supplies, high voltage cables, insulators, power management, switching and protection shield signaling; at the request of the customer interface is supplied to the output signal from the control unit electrical dehydrators on a shared computer the whole plant. Additional equipment is determined by the results of the design documentation for the whole property as a whole. Standard series of electrical dehydrators up the volume from 1 to 200 m3.

In the construction provided with electrical dehydrators vertical oil riser, which is provided, and selecting the optimum processing temperature regent will reach the output unit water content of 0.5%.

Depending on the amount of salt and water content in the oil can be provided as a circuit with two (freshwater provides input) and one electrical dehydrators (without deep dehydration of fresh water).
Developed designs always provide for cleaning electrical dehydrators from deposited dirt and mechanical impurities.

Modern production with the use of metal-cutting and welding systems world-class under the supervision of leading experts in the field of oil treatment ensures high quality workmanship and full compliance with the published specifications.

Description of the type design of the horizontal electrical dehydrator

   Electrical dehydrators is a cylindrical vessel, mounted on two saddle supports, one of which is movable, the second – fixed. On the cylindrical part of the body and the bottom are located technological fitting and hatches, manholes, as well as fitting and coupling for the installation of instrumentation and automation equipment.
By the inlet nozzle attached distributor of raw materials, including longitudinal bends with perforated placed on the lower semicircle holes. Along the length of each finger in the lower part via ribs attached bumpers.
In the upper half of the unit is placed electrode system consisting of an electrode and placed above them flooring combines the functions of the carrier force structure, site service centers and top grounded electrode. On the beams of the floor mounted support insulators for the suspension of the electrode. All electrodes are formed sections are placed on the beam.
<br><br>&nbsp;&nbsp;At the top of the unit is placed the power supply system includes establishing on-site services such as high-voltage power supply IPM bushing type IAP and current wire connecting bushing with a current carrying electrode rod.
The electrode system includes a plurality of horizontal grid electrodes suspended on the supporting PTFE insulators.
In the lower part of the apparatus there is a system of water output, consisting of perforated longitudinal collectors and the system is placed with the erosion of sediment uniformly angled nozzles through which water under pressure and leaves the sediment erosion occurs in the apparatus.

  Конструктивно фильтр представляет собой вертикальный цилиндрический сосуд, работающий под давлением и подлежащий регистрации в органах Госгортехнадзора РФ. На корпусе фильтра размещены патрубки для присоединения к трубопроводной обвязкя, а также для размещения различных приборов и датчиков для контроля процесса фильтрации.

  Изнутри к обечайке корпуса фильтра приваривается опора-мембрана, представляющаа собой металлический круг с технологическими отверстиями для прохождения рабочего продукта в фильтрующие секции сосуда и обратно. На опоре-мембране располагаются крепёжные патрубки для установки сепарационных и коалесцирующих элементов.

Electrical dehydrators works as follows (the typical scheme)

Crude oil is heated in admixture with the wash water and demulsifier supplied through a feed distributor, it flows from the holes and is reflected from the impingement moves up through the first layer of the supernatant water, and then through a weak electric field between the electrode and the water level, then through a stronger field between the electrode and grounded flooring. During this movement the oil in the water drops grow in size and are deposited in the lower part of the apparatus.
Dehydrated oil is collected via two collections and removed from the machine.
Water collects in the bottom of the unit and is also derived from electrical dehydrators.
The water level is maintained automatically between the feed distributor and the lower electrode.
