Why is gas-liquid separation so important to us? Removing liquid from gas is of critical importance in the refining process. Mixed or contaminated streams can cause damage to downstream processing equipment. Equipment damage and general velocity reductions due to contaminated flows can increase plant downtime and exponentially increase operating costs. It is our goal at Ed W. Smith to provide clients with the highest-grade internal separation equipment to decrease their out-of-pocket costs by preventing damage and minimizing downtime. These are just a few of the potential benefits of integrating an Ed W. Smith vane pack to your industrial processing equipment:

  • Reduced downstream contamination
  • Cost savings
  • Maximized heat transfer efficiency
  • Reduced energy consumption
  • Lower risk of hot spots and leaks
  • Preventing premature catalyst changeouts

The proven EWS stripping vane element packaged into custom designed and fabricated vane mist extractor assemblies is the key to achieving high efficiency liquid separation in process gas stream separator applications providing essential protection from entrained liquids for downstream equipment.

Traditional vane packs function on the governing principle of inertial impaction. A series of vanes oriented either vertically or horizontally are fastened together and placed within a pressure vessel. As a mixed stream of gas and liquid flows into the vessel and begins flowing through the vane pack, liquid droplets become trapped in the pockets and along the walls of the vanes. As larger droplets accumulate, the gravitational forces acting on the droplet exceed the inertial forces propelling the liquid forward. Liquid droplets begin to separate from the flow and fall down the vanes into a collection pan located at the base of the vane pack. Liquid accumulation may then be drained from the unit. Vane packs remove particle sizes down to 8 microns with 99.8% efficiency and can be run at greater velocities even with higher liquid loads.

Our patented vane design has kept Ed W. Smith Machine Works at the forefront of the gas-liquid separation industry for decades. Our vane packs are used heavily in industry with great removal efficiency down to 8 microns. We realize that every industrial application is unique. That’s why we choose to tailor solutions exactly to our clients’ operating conditions. The result is that our housing sizing and velocities are always optimized.

Whereas many of our commercial competitors provide clients with exposed vanes, we provide our clients with a drop-in ready vane pack and housing. It is our belief that we are here to serve you which is why we provide ready-to-use vane packs rather than leaving you to construct your own housing. The EWS vane mist extractor is supplied as a complete assembly of vane elements contained in a fabricated housing custom sized and designed to meet customer specified operating conditions and each unique vessel arrangement. All of our vane packs are constructed of American-sourced 316SS and each one is custom welded to order in our Dallas fabrication shop. Contact us today to have your application sized and quoted. Additionally, EWS vane mist extractors are offered with either fixed or removable vane elements to suit the application requirements. Fixed vanes are well suited to most pipeline gas applications. Individually removable vane elements allow inspection & cleaning for applications subject to fouling.

Guaranteed performance, materials & workmanship

The separation performance of the EWS vane mist extractor is guaranteed when installed into the intended vessel design under the specified operating conditions. Materials and workmanship are guaranteed, and material test certificates are provided. EWS applies decades of experience when developing well engineered vane mist extractor solutions for each application. Early coordination with the customer’s overall separator design requirements ensures a well integrated vane mist extractor which can be readily installed at the customer’s chosen vessel fabricator.
