The Science and Technology of Hydrocyclones
The gas moves toward the center of the hydrocyclone with the oil and exits the unit through the reject port. A small amount of gas can improve performance, but too much gas disrupts the smooth flow of the oil core and bottlenecks the flow of oil out of the reject, Walsh said. Important trade-offs must be considered when designing a …
