“…Therefore, because the viscosities of the HS–ASQ formulations are relatively low, we opted to increase the viscosity with carboxymethylcellulose (CMC) in the study. Due to its low cost, its high ability to swell in water, and its lack of toxicity, CMC is a promising agent for dust suppression, as has been reported in numerous publications [ 28 , 38 , 42 ]. Figure 5 shows the kinematic viscosities for compositions without ( Figure 5 a) and with the addition of CMC ( Figure 5 b).…”

Humic-Based Polyelectrolyte Complexes for Dust Suppression

The present study proposes a novel application of humic substance–aminosilsesquioxane polyelectrolyte complexes (HS–ASQ) as dust suppressants. These complexes are synthesized through the reaction between humic substances (HS) and 3-aminopropyltriethoxysilane (APTES) in aqueous solution, resulting in the formation of active silanol groups that can bind to mineral surfaces and condense, forming gels. The HS–ASQ compositions were found to have a high sorption capacity for dust particles and could form coatings on their surface without cementing the dust, making them potentially useful for environmental applications. The viscosity of the HS–ASQ compositions can be controlled by adding carboxymethylcellulose (CMC), which also enhances their dust suppression abilities. Different compositions of HS–ASQ were synthesized by varying the proportions of APTES and CMC, and dust treated with these samples was assessed for its resistance to wind erosion using a laboratory-scale setup. Treatment with the HS–ASQ composition resulted in substantial reductions in PM10 and PM2.5 concentrations (particulate matter with aerodynamic diameters of 10 µm and 2.5 µm, respectively) of up to 77% and 85%, respectively, compared to the control.

“…Other surfactants such as sodium carboxymethyl cellulose solution (SCMS) have been investigated on dust suppression under the wind velocity of 15 m s -1 . Dust suppression is improved from 94.3% without using surfactant to 99.2% with 0.1% of SCMS by mass (Borowski et al, 2020).…”

Re-suspension of iron ore dust presents a constant hazard in the working environment within steel production plants. Herein, the optimal operating parameters for maximum dust suppression efficiencies through a water mist generator and a conventional sprinkler for particulate matter (PM) originating from an iron ore pile measuring about 2 m in height and with a stacking angle of about 30° are investigated. The effects of operating parameters including wind velocity, spray angle, and mode of water supply on dust suppression efficiencies are evaluated. Size differentiated PM samples were collected from the upwind and downwind locations of the iron oral pile and the dust suppression efficiencies are determined. The operating parameters with the highest dust suppression efficiencies using the water mist technology are low spray angle, low wind velocity, and intermittent water supply, while those for water sprinkling technology are high spray angle, low wind velocity, and intermittent water supply. The average dust suppression efficiencies for Total Suspended Particles (TSP), PM10, and PM 2.5 for the mist generators are 80.9%, 77.9%, and 76.9%, respectively, whereas those for the conventional sprinklers are 76.4%, 72.9%, and 72.7%, respectively. For the surfactant to water ratios of 0.024, 0.022 and no surfactant, the ratio of 0.024 had the highest dust suppression efficiencies for TSP, PM 10 , and PM 2.5 at 90.9%, 89.5%, and 89.0%, respectively. Insights from this investigation can be applied to optimize the dust suppression methods to ensure economical consumption of water and energy.

“…In order to exclude the possibility of static electricity occurring during sulfur granulation, measures of sulfur irrigation with water are taken at all points of its reloading, and in some cases, it is treated with a dust suppressant solution. It is noted that these methods of coping with negative effects of sulfur electrification and the formation of sulfur dust have significant drawbacks, specifically, the impossibility of using aqueous solutions in winter due to them freezing [63].…”

Nowadays, sulfur is considered one of the primary resources of the chemical industry, most of which is produced as a refinery by-product during the processing of oil and natural gas. Sulfur production volumes are increasing every year, while the demand for it does not always match the growing supply, which leads to a serious problem of sulfur surplus in the world market. Granulated sulfur -the main commercial type of elemental sulfur -is transported in large quantities both by land and sea and can have a negative impact on the environment. At the moment, the issue of the negative impact of granulated sulfur on the environment has not been fully studied, which determines the relevance of this research. This review article presents the global market of granulated sulfur, paying attention to its safe transport -from the producer to the consumer. The potentially harmful factors of the impact of sulfur handling on elements of the natural environment, such as atmospheric air, water reservoirs, soil and vegetation, were also taken into account.
