Fully automatic crude oil dehydrator

1Intelligent crude oil dehydrator JFY-3AtypeOverview

Crude oil dehydration is the most basic process requirement in the process of oil extraction, transportation, and refining. The classic dehydration method consists of natural settling, heating separation, etc. Due to the increasing differences in oil storage in different oil fields, the original dehydration process can no longer meet the needs, especially for heavy oil, which requires heating24Even hours cannot effectively separate oil and water. Developed by our factoryJFYThe series of multifunctional crude oil dehydration testers adopts the treatment method of "electrochemical method as the main method, thermochemical method as the auxiliary method", effectively solving the problem of difficult dehydration and desalination of heavy oil. Through experiments, it has been found that heavy oil is generally usedJFYThe series of fully automatic crude oil dehydration testers only require1Oil and water can be separated within hours. This instrument has program segment temperature control, three-stage program segment application of high-voltage electric field, adjustable electric field size, adjustable test time for each segment, automatic heating, stirring, electric field application, drainage, distillation, cooling, oil recovery, and automatic cleaning functions according to program settings. In addition, to ensure the safety and reliability of the experiment, the instrument also has functions such as high voltage overcurrent protection, over temperature and over pressure (pressure) power-off protection, and sound and light alarm. It is actually an ideal experimental device for various research departments to study crude oil dehydration and desalination.

3Basic components of the instrument

The testing device consists of three main parts:

3.1control circuit

The control circuit consists of a computer, PLC controller, input/output devices, automatic drainage, and automatic mixing. According to different oil products, users can freely set the heating temperature, high-voltage electric field strength, and time control. When the oil composition is complex and strong electrolytes are encountered, the instrument automatically enters overcurrent protection. When the overcurrent factor does not exist, the high-voltage electric field can be automatically restored. If the temperature is out of control or the pressure is too high, the power will be automatically cut off and an audible and visual alarm will be issued, which improves the safety factor of instrument operation.

3.2Dehydration tank

The dehydration tank is composed of an oil injection port, a main tank body (i.e. dehydration tank), automatic cleaning, electrode electric field dehydration, cooling, gas path, water path, oil path, and control valve body.

3.3Atmospheric pressure evaporation synthesizer

The evaporation synthesizer is a key component of precision dehydration, consisting of a cold well, refrigeration system, oil-water separation chamber, etc. Its function is to automatically reflux light oil, separate and discharge water.

3.4Pressure evaporation synthesizer

It is composed of a cold well, refrigeration system, distillation receiving chamber, and other components, similar to the atmospheric evaporation synthesizer.

3.5automatic cleaning

（1） Inject 1L of kerosene or diesel into the cleaning bucket, turn on the power, and turn on the cleaning switch.

（2） Open the drain valve of the dehydration tank and discharge the cleaning waste oil.

（3） When observing and cleaning the waste oil until it is relatively clean, it proves that the tank has been thoroughly cleaned. The drain valve can be closed and opened to clean the residual crude oil in the drain pipe.

4The use and precautions of the instrument

4.1Preparation of instruments

4.1.1First, check whether all parts of the transported instrument are intact and whether the relevant connecting wires have come off. After confirming that there are no errors, proceed to the next step.

4.1.2Connect the power input line to the three-phase four wire distribution panel. If there is no three-phase power supply, the three-phase input lines can be connected in parallel220VAC power supply, but220VThe power of the AC power supply must be matched and well grounded.

4.2Use of instruments

4.2.1Inject crude oil into the main tank, or add a certain amount of water, turn on the main power supply and various sub power supplies in the control cabinet, and start the computer.

4.2.2Turn on the panel power switch,Open the desktop and enter the program.
