Propeller/mixer ends energy drain for refineries

Mixing Solutions present their combination Lancer propeller mounted on the Cutlass side-entry mixer, developed to virtually eliminate energy waste in refineries

Mixing Solutions will be showing their combination Lancer propeller mounted on the Cutlass side-entry mixer, which has been developed to virtually eliminate energy waste, especially welcomed by refineries with increased demands for refined products but facing rising costs.

A problem for refiners when pressured to operate at levels approaching maximum capacity is to ensure that fuel quality specifications are always fully met, which means that stored product must be thoroughly blended.

Many mixing processes waste large amounts of electrical energy, which is said to account for roughly half of the refinery operating costs.

The higher efficiency and effectiveness of the Lancer propeller eliminates this energy drain by developing a 'focused flow' that channels power into a jet-stream, maximising efficiency.

Compared to 'pitch adjusted propellers' and other mixing systems from other companies, the Lancer generates increased penetration, produces higher upward velocity movement which ensures that the tank contents are 'rolled' bottom-to-top-to-bottom for the most accurate blending.

Users tests with the Lancer/Cutlass combination, report a full 2:1 mixing advantage, with mixing time cut in half for the same energy input.

Additionally, the design of the Lancer/Cutlass system also incorporates a mechanical shut-off device that is engineered to adhere to the strictest environmental regulations.

The shut-off device is designed into the shaft and mounting flange with a stainless steel taper-to-taper shut-off feature that securely "locks" the system so that no leakage occurs during bearing and seal change-out procedures.
