VANE SEPARATORS (CHEVRON)
Galiakotwala Engineering has supplied advanced Mist Eliminator systems manufactured from speciality materials to 216+ Chemical Plants in 41+ countries across the world.
Vane Separators are primarily used to remove coarse and viscous mist or spray (which may contain solid particles) from gas streams. They are typically installed in towers or housed separately. These separators feature specially designed vanes with precise geometries and are available in various materials (plastics and metals), sizes, and configurations.
Vane Separators can be customized for new plants based on required gas flow, removal efficiency, pressure drop, and fouling potential.They can also be manufactured as replacements for existing plants, maintaining construction specifications as per the original design. Two flow orientations are possible: horizontal flow and vertical flow.
How It Works
In horizontal installations, liquid droplets flow upward through the Vane Separator. While the gas passes freely between the vane surfaces, the droplets—due to their greater inertia—cannot follow the sharp directional changes. As a result, they collide with the Vane surfaces and temporarily adhere. Over time, the droplets coalesce, grow in size, and drain down to the bottom of the Vane Separator before falling into the collection unit. The outgoing gas is largely free of entrained liquid, with only minimal fine droplets remaining, which can be further removed using other Mist Eliminators from Galiakotwala Engineering.

Material of Construction
Galiakotwala Engineering Company can manufacture Vane Separators from a whole range of conventional and specialty materials including:
- Carbon Steel
- PVDF
- Stainless Steel
- Polypropylene
- Special Alloy Steel
- Titanium
Collection Efficiency and Pressure Drop
- Vane Separators exhibit good collection efficiencies for particles 7 microns and above. They have very low pressure drops, usually within a few millimetres of the water column, provided they are not clogged with insoluble solids.
Advantages of Vane Separators
Depending on the application, some or all of these advantages can be realized.
Reduced Equipment Maintenance
- Reduces or eliminates corrosion, plugging, or fouling of downstream equipment.
Product Purity
- Reduces or eliminates carryover of liquid particles that may contaminate expensive products in chemical processes.
Efficient Handling of Solids and Viscous/ Sticky Liquids
- Can handle solids and viscous or sticky liquids that foul other types of Mist Eliminators.
- Vane Separators provide better drainage and are less prone to plugging.
Low Pressure Drop
- Maintains a lower pressure drop than other types of Mist Eliminators.
Improved Process Design
- By removing contaminants from gas, it eliminates the need for costly materials in downstream equipment.
- Allows for more efficient operating conditions.

What Our Customers Say
“I am pleased to report that since installing the GEC BMW Type Candle Filter in our Interpass Absorption Tower (IPAT) at our Sulphuric Acid Plant in 2019, it has performed exceptionally well. We have not observed any acid condensate at the outlet of the IPAT, indicating the filter is effectively removing any impurities.”

“We were facing mist carryover problems in the Drying Tower for a long time. We discussed the problem with the Galiakotwala Technical Services (GTS) Technical team.They studied the issue and gave the solution of an advanced Demister Pad of SX Wire Mesh for Drying Tower and solved this prolonged problem permanently.”
General Manager (Auxiliary),
Century Rayon
“Galiakotwala Engineering Company has provided us with the best solution in form of Alloy Piping to get rid of continued issues of leakage in conventional Sulphuric Acid Piping. After installation of the Alloy Piping, we observed zero leakage and significant cost savings due to reduced downtime. Since then we have changed most of our Acid Piping in both Sulphuric Acid Plants at Haldia with their low corrosion alloy.”
General Manager (Engineering),
Tata Chemicals Limited, Haldia
“We wanted to replace our old Brick-Lined Acid Towers with a newer technology due to difficulty in location and repair of leaks in these Acid Towers. GEC gave a solution of an complete Alloy Tower 7500 mm in diameter including all internals such as Distributor, Mist Eliminators, Packing and Support, etc. We are happy to note we have observed no corrosion in last 7 years and achieved 99.99% absorption efficiency.”

Russia
“We were continuously facing excess mist generation and moisture carryover problems in FAT and DT with the conventional distributors. Galiakotwala Engineering Company (GEC) replaced conventional distributors with Alloy Distributors in 2004. Since then, there is no change in the thickness and deformation of hole sizes of the branch pipes of the distributor. We appreciate the quality of work and and the materials used by GEC even after 18 years of operation.”
Deputy General Manager (Mechanical),
Paradeep Phosphates Limited
“We are using your Vane Separators for the last 15 years and have never faced any issues in the performance or life of the equipment. We are thankful to the Galiakotwala team for designing the special type Vane Separators according to our requirement that continues to ensure our process operates.”
Sr. Manager (Mechanical),
TATA Steel
“In 1987, Galiakotwala Engineering Company (GEC) provided our first Shell and Tube Type Heat Etxchanger with the assurance of an advanced, efficient design and manufactured with a low-corrosion alloy that would extend its lifespan. Even after 30+ years of trouble-free operation, the Heat Exchangers are still functioning effectively. We are pleased to report that GEC adhered to their commitments.”
