Product details
Characteristics and working principle of a rapid water content analyzer for crude oil
1. This instrument adopts a heating sleeve for non open flame heating, with fast heating, low power, uniform heating, and high efficiency.
2. Magnetic stirring is a closed magnetic stirring method that avoids sudden boiling and achieves rapid oil-water separation.
3. In the automation and self-control parts, the timer is the heating power switch, which sets the required time and automatically shuts down the power when the time is up. By using gas sensing probes instead of manual monitoring, if the height of oil and gas rise exceeds the specified standard, the instrument automatically cuts off the power supply and starts the axial flow fan to quickly cool down the furnace body, thereby avoiding the phenomenon of sudden boiling and sample collision and achieving safety.
4. Equipped with a pure water automatic cooling tank, it prevents the yellowing and scaling of glass instruments, and solves the problem of water shortage in field operations.
5DGNThe model is equipped with a glass instrument quick drying oven and a heating air duct for condensing air drying. In order to address the impact of external cold air on the receiver, it is equipped with a temperature protection device, which solves the problem of premature condensation of water vapor and backflow of water droplets, achieving the goal of rapid evaporation of moisture.HL1000Type, equipped withXAHot air flow rapid constant temperature dilution instrument, which can be heated at once6It can also dry glass instruments.
2、 Indicate
This instrument relies on high-temperature distillation to increase the temperature of crude oil, so that the temperature of water in the oil reaches100Above the temperature, it turns into steam and is magnetized to allow the iron substances in the oil to rotate at high speed, causing the emulsified water to quickly separate and the water in the oil to evaporate rapidly, achieving the goal of rapid measurement. Therefore, the diluent added should not exceed150Ke (Sampling)200Otherwise, a large amount of light component gas will quickly enter the condenser tube. Once it encounters the gas sensing probe above, the instrument will automatically stop heating and enter a cooling state, which cannot achieve the rapid effect. Due to differences in scale, facilities, and workload among different units,DGN（HL）The series of crude oil water content measuring instruments are equipped with the following specifications for reference:

Due to different water contents in crude oil, the sampling amount also varies100Crude oil can be diluted with diluent40Ke -50Ke, take crude oil50Add diluent30The distillation time remains unchanged,HL1000Type of crude oil extraction100G, diluent60Ke.
The purpose of crude oil determination is to completely separate oil and water and accurately measure the water content of crude oil. Therefore, whether it is rapid or long-term distillation, only by measuring accurate values can the requirements be met. Users can adopt this methodHL1000Comparative experiments are conducted between the measurement results of the series products and other instruments. If there is indeed an error in this product, our factory is responsible for repairing or returning it. Practice has proven that usingHL1000Type of instrument only used20In minutes, the original instrument can pass through60－90Accuracy measured in minutes, saving solvents2.6Double energy-saving5times,Improved work efficiency4More than double,If users have strict regulations on distillation time and solvent dosage, this product can also be used for addition400The specific operation method for long-term distillation of solvent gasoline (xylene) remains unchanged,Just adjust the voltage to150VJust enough.
