Black Powder Removal Filtration Systems
IFS Black Powder Removal Filtration Systems are designed to remove Iron Sulphide, Iron Oxides and other contaminates from gas transmission lines. Black powder is known for being detrimental to pipeline equipment and for causing operation and maintenance issues. Understanding its physical characteristics is necessary in order to consider the appropriate separation technology. Because particle size distribution can vary wildly from one location to the other, IFS, in collaboration with our technology partner Jonell Inc offers a range of proven technology solutions.
Technologies: Wet & Dry Gas
- Combination cyclonic and high efficiency filters
- Membrane filtration
- Combination depth / surface micromedia allow for particle based filtration
Cyclonics with Post Filtration – If there are liquids or large amounts of solids present in the gas, one of the best ways to remove them is to utilize the combination of cyclones (for bulk removal) and filters (for fine particle separation). These typically consist of Multicyclones as the first stage pre-separator and a filter-separator as the cleanup for a wet system or a dry gas filter for a dry system.
Membrane Filtration – With the average particle size of black powder in the sub-micron range, the easiest way to ensure removal is to have a barrier which contains pores smaller than the containment you are trying to filter. Since black powder is small enough to pass through most process filters (even those with 99% removal of 1 micron particles), membrane media is often utilized.
Particle-based Separation – One of the remarkable properties of black powder in its dry condition is its ability to fill large volumes of separators without generating a significant differential pressure associated with solid accumulation. The flake-like nature of the containment means that that it will behave similarly to a stack of cards. While the structure may seem solid, the majority of this is void space. By altering the spacing between the elements, and changing the inlet configuration, our vessel design takes advantage of the black powder to self-filter.
