Types of oil and gas separators:
1. Gravity separation type: horizontal and vertical gravity separators are commonly used
2. Collision separation type: wire mesh coalescing, corrugated board coalescing separator
3. Cyclone separation type: reverse flow, axial flow cyclone separator, compact gas-liquid separator
4. Rotary expansion type; the heat transfer oil must be injected into the system from the expansion tank through the oil and gas separator.
