“…For example, thiourea, xanthate, thiol, and dithiozone were successfully employed as ligands on adsorbents for binding Hg(II) ions. Alternatively, non‐modified adsorbents such as activated carbons, specially designed polymers, silicates, clays, chitosan, and specific bacteria have shown promising behavior toward mercury removal . Specifically, the complexing capability of N and O atoms against Hg(II) can lead to the development of alternative mercury removal systems.…”

A novel sulfur-rich adsorbent, poly(BA-ala-co-sulfur), was synthesized by reacting allyl functional benzoxazine (BA-ala) and elemental sulfur. Simultaneous inverse vulcanization and ring-opening reactions of benzoxazine generated copolymers in several feed ratios. The adsorption behavior of these copolymers was investigated in aqueous solutions containing Hg 21 . A three level Box-Behnken design with four factors was applied in order to examine the interactive effect of Hg 21 concentration (ppm), S % in adsorbent, temperature, and pH. The optimum adsorption conditions were determined as: 10.33 ppm Hg 21 , 68% S content, 329 K, and pH 6.3. Common isotherm and kinetic models were applied to the experimental data, where the Langmuir isotherm provided the better fit (q max 5 79.36 mg g 21 ) and the pseudo-second order fit indicated chemisorption as the process-controlling step.

“…Many researchers have been focused on searching other low-cost and versatile alternatives to ACs (Pflughoeft-Hassett et al, 2009). A wide kind of mineral sorbents, such as sepiolite (Mendioroz et al, 1999), mordenite (Eswaran et al, 2007), zeolite (Morency et al, 2002;Jurng et al, 2002;Qi et al, 2015), bentonite and other similar kind of sorbents (Ding et al, 2012;U.S. EPA, 2003), displayed results comparable with activated carbons.…”

Mercury removal from MSW incineration flue gas by mineral-based sorbents

Three samples of commercially available mineral-based sorbents (zeolite, bentonite and diatomaceous earth) were selected and evaluated for Hg capture under conditions of simulated dry flue gas atmosphere typical in Municipal Solid Waste Incineration (MSWI). The experiments were carried out in a lab-scale fixed-bed device at temperatures between 120 and 200 °C. Two samples of activated carbons (AC) (raw-AC and sulphur impregnated AC) were tested under the same conditions. The mineral-based sorbents were chemically promoted by sulphur, FeCl and CaBr, achieving an improvement in the overall reduction percentage of Hgout (g) up to 85%, which was comparable to that obtained using a commercial activated carbon for Hg capture (sulphur impregnated AC). The study demonstrates that sorbents with a matrix relatively richer in TiO, FeO and AlO, as bentonite, favour Hg heterogeneous oxidation. The best Hg capture capacity was achieved with a zeolite sorbent sample characterized by high specific surface (132 m/g) and impregnated with elemental sulphur. The final form of mercury retained in this sorbent was HgS with proved long-term stability in disposal and landfilling. The higher the temperature, the lower the efficiency of Hg capture being the optimum temperature for Hg-capture in the range of 120-150 °C. This study provides a basis for the development of new efficient non-carbon sorbents for mercury removal in the air pollution control lines of MSWI facilities considering the non-hazardous final form of mercury and its long-term landfilling/sequestration.

“…The temperature dependence is also supported by other sources. [101][102][103][104] From available literature, dedicated mercury cleaning appears to be common practice for manganese plants only in Norway. In the early 1990s, Tinfos Jernverk discovered mercury emissions, and developed a process for off-gas cleaning.…”

Airborne emissions from metal production represent a health, safety, and environmental challenge to which more and more attention is being directed. Industries worldwide, as well as authorities and others, are resolute in their aim of limiting, reducing, and ultimately eliminating these emissions. Many lessons can be learned by sharing information between industrial branches, as many industries face similar challenges. Certain challenges are, however, highly branch specific. For the Mn ferroalloy industry, such examples include the types of dust generated in the primary processes and the management of polycyclic aromatic hydrocarbons (PAHs) and mercury with respect to furnace design and operation. This article covers airborne emissions from manganese ferroalloy production, including greenhouse gases, nitrogen oxides (NO x), sulfurous gases, PAH, airborne particulate matter, and trace elements, including mercury and other heavy metals. The aim is to summarize current knowledge in a state-of-the-art overview intended to introduce fresh industry engineers and academic researchers to the technological aspects relevant to reduction of airborne emissions.
