Hydrocyclones first came into use in the mid-1980s and became standard equipment for oil and water separation in most offshore fields by the early 1990s. Today, they are also used in approximately 20% of onshore fields. John Walsh, director of technology at CETCO Energy Services, spoke at a webinar titled "Hydrocyclones—The …

That means, changing feed properties must be compensated by a hydrocyclone control system, ensuring that the following conditions be achieved: 1. Stabilizing the properties of the hydrocyclone overflow at a constant mill feed rate and fluctuating material hardness. 2. The maximum particle size in the hydrocyclone …

The structure of the hydrocyclone is relatively simple. Its upper end is a cylindrical part, and its lower part is a conical container. The slurry is fed into the cyclone at a certain speed (generally 5 to 12 meters per second) along the tangential direction, and obtains a rotary motion, thus generating a large centrifugal force (usually tens of times or even hundreds …

The valves were then opened and the corresponding pump (P-1 or P-2) switched on at the minimum pressure the hydrocyclone could operate. After waiting 5 min for stabilisation, the flow rate and pressure were registered and samples were collected from the underflow and overflow streams. Afterwards, pressure was increased and the …

For a hydrocyclone to work at peak efficiency the volume of slurry and the feed pump delivery pressure must remain constant. If the cyclone feed pump is allowed to SURGE, the up and down pressure will cause poor separation at the point of high and low operating pressure.
