High-Efficiency Vane-Type Separator

The high-efficiency vane-type separator is a gas–liquid separation solution with high efficiency, large processing capacity, and low operating and maintenance costs. It can be subdivided into the following types:

High-Efficiency Axial Vane Separator

Working Principle:

(A) Gas containing entrained liquid droplets enters the separator, where its volume expands and primary separation begins.

(B) As the gas passes through the vane section, it undergoes multiple rapid directional changes. Under centrifugal force, the droplets collide repeatedly with the vane surfaces. After adhering to the vanes, the droplets coalesce into a liquid film. Driven by gravity, surface tension, and gas kinetic energy, this film is directed into the vane channels, where it merges into liquid streams.

(C) Under the influence of gravity, the liquid streams flow to the bottom of the separator and are ultimately discharged.

Key Features & Benefits

High gas handling capacity

High liquid separation efficiency

Low pressure drop

Resistant to clogging, no maintenance or replacement required

Reduced footprint, particularly suitable for limited installation space and piping connections

Various connection configurations can be designed according to site-specific requirements

High-efficiency coaxial vane separators are commonly used in air drying and steam dewatering systems of industrial facilities. Vessel diameters typically range from 150 mm to 500 mm, with pressure ratings up to 5 MPa.

When installation space is limited or piping connections do not allow the use of a high-efficiency coaxial vane separator, our high-efficiency off-axis vane separator can meet specific customer requirements. Common connection configurations include six types (see A–F).

Technical Specifications

The high-efficiency axial vane separator ensures 100% removal of liquid droplets with diameters of 8 microns or larger. At maximum design capacity, the total liquid carryover in the outlet gas does not exceed 0.1 U.S. gallons per million standard cubic feet (13.4 liters per million standard cubic meters).

Combination Structures of High-Efficiency Separation Vanes

High-efficiency separation vanes are typically designed in different combination structures to meet process performance requirements and vessel dimensional constraints. The unit combination structures of high-efficiency separation vanes generally include four basic forms: single-vane set, double-vane set, four-vane set, and eight-vane set. When process performance and vessel dimensions have specific requirements, high-efficiency separation vanes can also be designed in targeted combination structures to meet special customer demands.

Comparison of High-Efficiency Separation Vanes with Conventional Wire Mesh

Compared with conventional wire mesh, high-efficiency separation vanes offer significant techno-economic advantages.

The vessel dimensions required for designs utilizing high-efficiency separation vanes are typically reduced by at least 30–40% compared with conventional wire mesh designs, resulting in lower capital investment and reduced footprint.

High-efficiency separation vanes are formed by pressing smooth stainless steel plates, making them resistant to damage and clogging. Their daily operation, maintenance, and shutdown overhauls incur very low costs, while their service life far exceeds that of conventional wire mesh.
