What is a glass separator?

A glass separator is a machine that separates mixed substances into two or more different substances. Common separators include centrifugal separators and electrostatic separators. In order to maintain good separation effect, the liquid level and pressure of the separator should be controlled. The liquid level and pressure of traditional separators are controlled by constant pressure control technology. In the variable pressure liquid level control of the separator, the float level controller is used to drive the oil and gas regulating valve so that they work together to control the liquid volume of crude oil and natural gas, and complete the liquid level in the separator without controlling the separator pressure. adjustment. The variable pressure liquid level control method can reduce the throttling of the oil and gas outlet valve, reduce the separator pressure, and improve the separation effect. Oil and gas separators and oil, gas and water three-phase separators are widely used in oil field transfer stations and joint stations. In order to maintain good separation results, the glass separator needs to control its liquid level and pressure.

When the controller of the centrifugal glass separator is powered on, the strong negative pressure generated by the oil mist suction port causes the oil mist to be directed into the oil mist absorber. The oil mist particles collide under the action of the wind wheel in the mist aspirator. The small particles aggregate into controllable larger particles, which are intercepted by the high-efficiency mist suction material and collected and recycled through the return port.

According to the secondary principle of electrostatic field, the electrostatic separator causes fine oil mist particles to enter the strong electric field with the air flow and brings positive electricity. When the particles with dots reach the electric field between the purifier collection plates, the particles are attracted by the metal washing plate and adhere to the metal plate, thereby separating the oil mist from the air and achieving the purification effect.

Comparison of centrifugal and electrostatic oil mist separators: Centrifugal oil mist separators are widely used and do not have high requirements for multi-workshop environments; electrostatic oil mist separators can only be used in relatively dry workshop environments. For workshops with very heavy fog, the conductivity of water can easily short-circuit the electric field of the oil mist glass separator.

The separation effect of the centrifugal oil mist glass separator is not as good as that of the electrostatic separator. The diameter of the separable particles of the electrostatic oil mist separator can be as small as 0.01μm.

The oil and gas two-phase separator separates the incoming liquid of the oil and gas mixture into single-phase crude oil and natural gas. The pressure is controlled by the pressure control valve at the natural gas outlet, and the liquid level is adjusted by the oil delivery valve controlled by the controller.

The pressure control valve at the natural gas outlet is usually a self-operated regulating valve or a supporting pressure transmitter, controller, air source pneumatic diaphragm regulating valve, etc., controller and air source.

Some oil and gas two-phase separators use a pneumatic diaphragm control valve to control the pressure of the separator, and a float level regulator to control the liquid level of the separator. The oil, gas and water three-phase separator can separate part of the water in the crude oil while separating the oil well products. With the development of oil fields, the water content of oil well produced fluids gradually increases, and the application of three-phase separators also gradually increases. The control methods of three-phase separators vary depending on the structure.
