Featured in Dry Cargo International: The Challenge of Corrosive Dust: Integrating a Wind Fence for Optimal Dust Control

We’re excited to share that WeatherSolve Structures has been prominently featured in the November 2024 issue of Dry Cargo International.  The article, titled “The Challenge of Corrosive Dust: Integrating a Wind Fence for Optimal Dust Control,” explores the complex challenges of corrosive dust generated during fertilizer production and petroleum refining. It highlights the critical role of a custom-designed wind fence in mitigating this serious threat to employee health, safety, the environment, and surrounding assets.

The editorial notes that many chemicals used in fertilizer manufacturing are highly corrosive and require specialized storage and handling. Wind fences, as porous structures, control dust through two modalities: the upwind fence dramatically slows wind speeds (by approx. 50-75% on the leeward side), and the downwind fence functions as a catch fence, causing airborne dust to settle. Using a porous material minimizes the formation of turbulent eddies and wakes seen with solid barriers.

Proven Results: Durability in Extreme Environments

The feature focuses on the unique material engineering required to withstand highly corrosive atmospheres:

  • The resulting protected area behind an upwind fence extends for 1-2 shelter lengths downwind.
  • The central challenge in corrosive environments is creating a durable fence resistant to chemicals like sulfuric acid.
  • The successful solution used was a fence entirely made from extremely corrosion-resistant materials.
  • Key components included: Kevlar cables coated with PVC, polypropylene wind-fence fabric (very chemical resistant), stress-rated nylon attachment clips, and oversized polished marine-grade stainless steel fittings.

WeatherSolve in Action

The article details a project at a refinery in the Atlantic Basin that was subject to steady winds and a highly corrosive environment. The primary goal was to prevent coke dust (from the petcoke storage area) from contaminating the downwind sulfur production facility and the nearby marine environment.

The solution involved a wind/dust fence that separated the two areas. The fence also featured an inclined upper section to improve the control of turbulent vortices that might otherwise lift dusty eddies over the fence. The final outcome was a durable and effective fence that successfully protected the environment and preserved assets while enduring the corrosiveness of the environment.

This case study demonstrates that by employing innovative designs and appropriate materials, custom wind fences offer a practical and effective solution to mitigate the harmful effects of fugitive dust in corrosive settings.
