P-KLONE™ Hydrocyclone Oil-Water Separation
The P-KLONE™ Hydrocyclone is a highly efficient and economic approach to processing oil-laden water. It is a well-proven method for taking water from the production separator with oil concentrations up to 5% and readying it for secondary treatments such as induced gas flotation or filtration. The hydrocyclone can be designed to handle any flow volumes and output pressures you require. P-KLONE™ is small, lightweight and insensitive to orientation or motion, making it an ideal solution for offshore and space-constrained onshore applications.
How it works
P-KLONE™ converts the velocity of water flowing from the production separator into centrifugal force. The shape of the unit causes the water to form a vortex, much like a whirlpool. The water moves faster as the sides taper in, causing a reverse-flowing low-pressure area in the center. The heavier water moves to the outside wall of the unit, while the lighter oil concentrates in the center. Water exits at the clean-water outlet and the oil exits at the opposite end. This entire separation process happens in less than two seconds.

Key Benefits
Cost-Savings
- Cost-effective, efficient way to reduce oil concentration prior to secondary de-oiling.
- Eliminates the cost of a feed pump by using existing process pressure.
- Easy to ship, install and start up, making it ideal for temporary and long-term projects.
Better Performance
- Low risk technology, with nearly 30 years of proven performance and thousands of units in service.
- Easy to maintain with no moving parts, no failure-prone mechanisms, and no fugitive emissions.
High Flexibility
- Works flawlessly regardless of orientation or pitch and roll motions offshore.
- Wide turndown range allows flow rates ideal to your operation.
