Coal pollution mitigation - Wikipedia

Coal pollution mitigation, sometimes called clean coal, is a series of systems and technologies that seek to mitigate the health and environmental impact of coal; in particular air pollution from coal-fired power stations, and from coal burnt by heavy industry.. The primary focus is on sulfur dioxide (SO 2) and nitrogen oxides (NO x), the most important gases which caused acid rain; and

Electrostatic Precipitator - an overview | ScienceDirect

The process of trapping particulate matter by electrostatic precipitator includes four steps: (1) negative high-voltage discharge, flue gas ionization, generation of negative ions; (2) fly ash is charged by electric field and negative ions; (3) charged fly ash is collected to the anode plate; (4) after rapping, the fly ash on the anode plate

Blast furnace - Wikipedia

Blast furnaces operate on the principle of chemical reduction whereby carbon monoxide, having a stronger affinity for the oxygen in iron ore than iron does, reduces the iron to its elemental form. Blast furnaces differ from bloomeries and reverberatory furnaces in that in a blast furnace, flue gas is in direct contact with the ore and iron, allowing carbon monoxide to diffuse into the ore and

Multi Channel 4-Wire Analyzer FLXA402 | Yokogawa Electric

In flue gas desulfurization systems that use magnesium hydroxide (Mg(OH) 2) slurry, the consumption of the desulfurization agent (Mg(OH) 2) is controlled by using online pH analyzers. A great concern in the pH measurement is heavy staining of the pH electrodes by the Mg(OH) 2 slurry. To ensure accurate measurement, frequent cleaning of the

Circulating fluidized bed - Wikipedia

The circulating fluidized bed (CFB) is a type of Fluidized bed combustion that utilizes a recirculating loop for even greater efficiency of combustion. while achieving lower emission of pollutants.Reports suggest that up to 95% of pollutants can be absorbed before being emitted into the atmosphere. The technology is limited in scale however, due to its extensive use of limestone, and the fact

Glossary of Oil Industry Terms | OPIS

Petroleum desulfurization is a process that removes sulfur and its compounds from various streams during the refining process. Desulfurization processes include catalytic hydrotreating and other chemical/physical processes such as adsorption. Desulfurization processes vary based on the type of stream treated (e.g. naphtha, distillate, heavy gas

Wet Flue Gas Desulfurization (WFGD) unit based upon spray scrubber has been widely employed to control SO 2 emissions from flue gas in coal-fired power plant. To clarify the dependence of desulfurization performance on inter-phase transfer behaviors with non-ideal contacting patterns of flue gas and slurry droplets, three regions in spray scrubber are distinguished in terms of gas-slurry flow
