HAC Cyclonic Oil-Water Separator: CFD-Optimised Flow Field plus Strong Centrifugal Separation for Simultaneous Water Discharge and Oil Concentration
In oilfield produced fluids and oily wastewater treatment, how can a single unit solve two problems at once — "separation efficiency" and "oil-phase recovery" — at the same time? SINOKLE's HACcyclonic oil-water separator answers that question—— with axial cyclone technology at its core, balancing compliant discharge water with concentrated produced fluid.
Stable flow field: the first prerequisite for efficient separation
HACThe HAC cyclonic oil-water separator adopts a specially designed axial cyclone design and uses CFD simulation to optimise and create a comparatively stable internal vortex flow field. A stable flow field is the cornerstone of cyclone separation performance: only when the internal vortex field is stable and controllable can strong centrifugal separation act on every oil droplet continuously, evenly and efficiently, and can equipment performance become truly predictable.
Strong centrifugal separation: hundreds to thousands of times gravitational acceleration
Backed by the stable flow field, the unit can separate oil droplets from wastewater efficiently and rapidly under centrifugal forces of hundreds to thousands of times gravitational acceleration. The strong centrifugal field converts the density difference between oil and water into a powerful separation driving force: oil droplets converge quickly while the water phase is discharged efficiently, combining speed with depth of separation and delivering processing capacity that clearly outperforms conventional gravity settling.
Application envelope and quantified indicators
The product's operating envelope is clearly defined: it suits inlet oil content <50% (the incoming stream may contain a small amount of gas).
Two core indicators are worth noting:
- oil content in the water outlet reaches 500mg/L, giving stable and reliable water-phase quality;
- meanwhile the oil outlet concentrates the produced fluid, where 10% produced fluid can reach 50% oil content.
Meeting targets on both the water and the concentration line means the unit guarantees water-phase performance while efficiently enriching the oil phase, markedly improving the economics of the whole process.
Higher output, more oil: a productivity tool for high-water-cut wells
For wells with very high water cut, the produced fluid is lean in oil and expensive to recover. HAC By concentrating at the oil outlet, the HAC cyclonic oil-water separator highly enriches the oil in lean produced fluids, raising output and increasing oil recovery. It helps oilfields move from "inefficient processing"to"efficient recovery", unlocking the latent value of lean produced fluids.
Technical and engineering advantages
The product features super-hydrophilic surface modification: surface treatment strengthens water passage and suppresses oil-droplet adhesion, improving separation selectivity and efficiency. Its compact, high-efficiency design completes separation within limited space, making skid-mounted deployment and upgrades to existing processes straightforward.
Application scenarios and conclusion
Oilfield produced-fluid treatment, concentration of produced fluid from high-water-cut wells, and pretreatment of oily wastewater with inlet oil content <50% and a small amount of gas are all suitable applications for the HACcyclonic oil-water separator.
From a practical standpoint: for new stations, the compact structure means a smaller footprint and lower civil works investment; for brownfield upgrades, the flexible deployment minimises shutdown windows. Whether used for front-end oil-water separation or back-end concentration and recovery, the unit finds the right place in existing processes, helping sites capture both separation and recovery benefits at low retrofit cost. Stable flow field, strong centrifugal separation, super-hydrophilic modification and compact high efficiency — behind these technical labels lies real separation and recovery value. Compliant discharge, higher concentration and output: one unit, double the value — ——SINOKLE HACHAC cyclonic oil-water separator deserves close attention from the oilfield and environmental protection industries.
