The working principle of the gas-liquid separator: The saturated gas is cooled or pressurized, and part of the condensable gas components are liquefied to form small droplets and flow together with the gas.

The role of the gas-liquid separator: to process the gas containing a small amount of condensate, to achieve condensate recovery or gas purification.

Its structure is generally a pressure vessel with related air inlet components and droplet trapping components inside.

Generally, the gas is discharged from the upper part, and the liquid phase is collected from the lower part. There are two common separation principles:

1. Use different component mass (weight) to separate the mixture.

2. Separate the mixture by using the different particle sizes of the dispersion.

The separation methods are:

1. Gravity sedimentation: Due to the different density of gas and liquid, when the liquid flows together with the gas, the liquid will be affected by gravity and produce a downward velocity, while the gas still flows in the original direction, that is to say, the liquid and the gas flow together. The gas has a tendency to separate in the gravitational field, and the downward liquid adheres to the wall and gathers together and is discharged through the discharge pipe.

2. Baffle separation: Due to the different density of gas and liquid, when the liquid and gas flow together, if they encounter obstacles, the gas will baffle away, and the liquid will continue to have a forward speed due to inertia. The liquid adheres to the barrier wall and gathers downwards due to the action of gravity, and is discharged through the discharge pipe.

3. Centrifugal force separation: Because the density of gas and liquid are different, when the liquid and gas rotate and flow together, the centrifugal force of the liquid is greater than that of the gas, so the liquid has a tendency of centrifugal separation, and the liquid adheres to the separation wall and gathers downwards due to gravity. Together, they are discharged through the discharge pipe.

4. Screen separation: Due to the difference in particle size between gas and liquid, when liquid and gas flow together, if they must pass through the screen, just like sieving, the gas passes through and the liquid is intercepted and stays on the screen. Under the action of gravity, it flows down to the bottom of the separator and is discharged.

5. Ultrafiltration separation: due to the different particle sizes of gas and liquid, when liquid and gas flow together, if it must be filtered through micropores, it is like sieving. The gas passes through and the liquid is intercepted and stays in the micropores for filtering. On the separator, and flow down to the bottom of the separator to be discharged under the action of gravity.

6. Packing separation: Due to the different density of gas and liquid, when the liquid and gas flow together, if they encounter a barrier, the gas will buckle away, and the liquid will continue to have a forward speed due to inertia, and the forward liquid Adhering to the surface of the barrier filler, it gathers downwards due to the action of gravity and is discharged through the discharge pipe.
