Overview of mercury control in coal-fired power plants
During combustion, the mercury (Hg) in coal is volatilized and converted to elemental mercury (Hg0) vapor in the high temperature regions of coal-fired boilers. As the flue gas is cooled, a series of complex reactions begin to convert Hg0 to ionic mercury (Hg2+) compounds and/or Hg compounds (Hgp) that are in a solid-phase at flue gas cleaning temperatures or Hg that is adsorbed onto the surface ...

Reactive separation of CO2 using pressure pelletised limestone
Calcium oxide powder derived by the calcination of mesoporous calcium carbonate provides a higher conversion towards carbonation compared to calcium oxide derived from naturally occurring limestone and hydrated lime. Compaction of this high reactivity sorbent was investigated for its use in CO2 separation from flue gas. It was observed that compaction preserved the porosity of the powder. The ...

Control of Mercury Emissions from Coal-fired Electric Utility Boilers
During combustion, the mercury (Hg) in coal is volatilized and converted to elemental mercury (Hg°) vapor in the high temperature regions of coal-fired boilers. As the flue gas is cooled, a series of complex reactions begin to convert Hg° to ionic mercury (Hg2T) compounds and/or Hg compounds (Hgp) that are in a solid-phase at flue gas cleaning temperatures or Hg that is adsorbed onto the ...

Mercury emissions of the German cement industry - Case Study
In December 2019 the new BREF (Best Available Technology Reference) document for waste incineration was published in the EU. One important topic in the Best Available Technology (BAT) conclusions is the request for continuous monitoring of mercury (Hg) emissions. In the BAT conclusions are mentioned so-called BAT-Annual Emission Levels (AELs) for daily averages, with Hg concentrations in the ...

The Influence of PVC on the Quantity and Hazardousness of Flue Gas Cleaning Residues from Incineration
The study estimates the influence of PVC on the quantity and hazardousness of flue gas residues from incineration. The analysis has been carried out on both theoretical and practical terms. A distinction between dry, semi-dry and wet gas treatment systems has been made. The influence of PVC has been assessed on the combustion steps and therefore on the distribution of chlorine and other ...

Mercury: measure and control
Following the new EU BREF document for waste incineration, European cement plants have to implement the requirement to continuously monitor and abate mercury emissions. To enable this they will need to apply technologies that measure mercury in the raw gas and optimise sorbent use. In December 2019 the new BREF (Best Available Technology Reference) document for waste incineration was published ...

Pollutant reduction control and Continuous Emissions Monitoring at Waste-to-Energy Plants
Waste is generally undesired, and best not generated at all. The second best alternative to manage waste is to recycle it. However, there is also waste that for various reasons is not recycled. Landfills have then been the old-school solution, but it is for environmental reasons becoming a less viable option. What then remains is waste incineration, in most cases while recovering the energy ...

Industrial Wastewater Treatment: Priority pollutant behaviour in on-site treatment systems for industrial wastewaters
The majority of wastewaters deriving from the chemical industry consist of aqueous discharges produced during the physico-chemical processing of synthetic mixtures involving operations such as filtration, centrifugation, extraction and/or distillation. The wastewater streams, referred to as ‘process waters’ can include mother liquors, washing waters from the purification of products, ...

Regulating Mercury Emissions
Historically, mercury (Hg) has found its use in many products such as thermometers, batteries, and fluorescent lamps. However, mercury is extremely toxic, and it has in modern days been banned from use in most applications. By example, the Minamata Convention on Mercury from 2013 has been designed to prevent releases of mercury and mercury compounds in order to protect human health and the ...

Alstom power plant - Wastewater treatment plant for wastewater from flue gas desulfurisation - Case Study
In Portugal's largest coal-fired power plant, flue gas desulphurisation creates wastewater which still contains heavy metals, fluoride and ammonia after the separation of the FGD gypsum. The wastewater is treated with the EnviroChemie physico-chemical Envochem® COL process to maintain compliance with local limit values. The amount of wastewater that must be discharged from the flue gas ...

EVALUATION OF STRATEGIES FOR MERCURY MACT COMPLIANCE
On December 15, 2003, the United States Environmental Protection Agency (U.S. EPA) proposed a rule with two alternatives to permanently reduce mercury (Hg) emissions from power plants. Under one alternative, which is the focus of this paper, the utilities would install controls known as Maximum Achievable Control Technologies (MACT) under section 112 of the Clean Air Act (CAA). The proposed rule ...
