Technical description of parameters influencing the pH

Consequently, many studies in Poland and abroad address the impact of various parameters on the pH value of the sorbent suspension, such as the average diameter of sorbent particles (related to the limestone pulverization degree), sorbent quality (in terms of pure calcium carbonate [CaCO3] content of the sorbent material), stoichiometric

Assessment of marble waste utilization as an alternative

Dec 01, 2014 Overall, 70% of the WFGD systems use calcium-based material, mostly limestone, as SO 2 sorbent . In these systems, limestone is finely ground (95% passing 45 μm), and mixed with water to obtain a sorbent slurry. The overall reaction of post-combustion SO 2 control by this slurry is,: (1) CaCO 3 s + SO 2 g + ½ O 2 g + 2 H 2 O s → CaSO 4 2

remove these pollutants from the flue gas is by injection of sorbents downstream of a boiler and up-stream of a particulate control device. Activated carbon (AC) is a suitable sorbent to capture vapor-phase mercury and calcium-based sorbents such as quicklime (CaO) and hydrated lime (Ca(OH)2) are suitable sorbents to capture SOx and HCl.

Wet Limestone Carmeuse

Wet limestone systems are well established in some sectors such as the Power Generation industry. This process is based on the large degree of contact between the circulating slurry and the flue gases. This slurry circulates in the absorber tower (or scrubber) to neutralize the condensed flue gas pollutant, mostly SO2. The pH of the slurry is a key parameter to be monitored as

Spray Dry Scrubber an overview ScienceDirect Topics

Combining spray dry scrubbing with other FGD systems such as furnace or duct sorbent injection and particulate control technology such as a pulse-jet baghouse allows the use of limestone as the sorbent instead of the more costly lime (Soud, 2010). Sulfur dioxide removal efficiencies can exceed 99% with such a combination.
