Dust Suppression

Chemical suppression methods reduce between 85-90% of dust emissions in facilities.
The combination of chemical suppressants with containment equipment (belt cleaners), the use of skirts, rollers in good condition, and a good maintenance policy will increase dust suppression levels up to 99%.

WHY PETCOKE DUST SUPPRESSION?

Petroleum coke is a hydrophobic material. Large amounts of water are required to wet petcoke.
The material can be wetted by applying a chemical surfactant, which lowers
water’s surface tension, allowing the water to moist the petcoke particle and add weight to it.
The heavy particle will fall by gravity.
Chemical suppressants provide wetting abilities and allow smaller particles to adhere to large ones.

WHY SULFUR DUST SUPPRESSION?

Sulfur is a hydrophobic material. The application of water alone (and in large quantities) to mitigate the pile dust does not achieve the objective of reducing dust emissions, and results in the formation of unwanted by-products, such as sulfuric acid, which cause damage to equipment used and/or located in the area. In order to effectively wet the sulfur, so that small sulfur dust particles fall by gravity, a chemical surfactant must be used, which reduces the surface tension of the water and allows it to wet it. Dust suppressant application is usually done at transfer points where there is a drop of material.
Sulfur dust is an explosive material due to its low flash point (190 C). Strong electrostatic charges can form in the sulfur, in contact with air and especially in falling material, in the stacking process, or on its way, by means of conveyor belts, to the ship loader. Explosions and fires are caused by sparks due to friction or impact of metals in the solids conversion system. The reduction of these static charges can be obtained with an increase in humidity in the environment and/or the material.

In order to be able to carry out the stacking, the recovery of the material from the pile, and its subsequent loading of ships in a safe manner, and thus avoiding problems of fire and environmental contamination, it is recommended that a dust suppression technique be used during these operations.
