Electrochemical oxidation of sulfite ions in aqueous solutions
Gaseous pollutants that affect human health, destroy vegetation and damage materials and art treasures can be converted into harmless components by electrochemical reactions. Electrochemical gas purification methods can be applied basically in two steps. In the first step, gases to be removed are absorbed in an aqueous electrolyte. Then, in the second step, they can be converted into harmless ...

PADEP Transition from CAIR to CSAPR
As of January 1, 2015 the U.S. Environmental Protection Agency (U.S. EPA) has been implementing the Cross-State Air Pollution Rule (CSAPR) through a Federal Implementation Plan (FIP) that primarily impacts electric generating units (EGUs). This article reviews the transition of the Clear Air Interstate Rule and nitrogen oxide (NO2), sulfur dioxide (SO2) allowances to CSAPR allowances and ...

Acid Rain Progress Report
In 1990, EPA Congress established the Acid Rain Program under the Clean Air Act. The principal goal of the program is to achieve reductions of 10 million tons of sulfur dioxide (SO2) and 2 million tons of nitrogen oxides (NOx), the primary components of acid rain. These pollutants, in their various forms, lead to the acidification of lakes and streams rendering some of them incapable of ...

Flue gas treatment process
Flue gas treatment is a process that aims to reduce the emissions of harmful pollutants from the exhaust gases produced by industrial facilities, power plants, and other combustion processes. The treatment of flue gas is essential to mitigate the environmental and health impacts of air pollution. Various technologies and methods are employed in flue gas treatment, depending on the specific ...

Air pollution modelling of the Calabrian pine forests withered by the Yatagan thermal power plant, Turkey
The emissions from the chimney of the Yatagan thermal power plant have caused a 3050-hectare forest to wither. Such air pollutants as sulfur dioxide, nitrogen oxides and fly ash are carried towards the Bencikdagi Calabrian pine forests on the prevailing north-east winds. To study these effects, the Q-Basic computer program developed for the Gaussian puff model was used with meteorological data ...

Flue gas desulfurization in power plants
Flue Gas Desulfurization (FGD) is a technology used in power plants to remove sulfur dioxide (SO2) from the exhaust flue gases produced during the combustion of fossil fuels, especially coal. SO2 is a major contributor to air pollution and acid rain, and its removal helps mitigate environmental and health impacts. There are several methods of flue gas desulfurization, with the two most common ...

4 Best Industrial SO2 Gas Detectors
Why do you need a gas detector? In the process of industrial production, flammable, toxic, harmful gas leakage occurs from time to time, will cause serious threats to personnel, equipment, production, life. The main causes of leakage are: 1. Material defects in production equipment or containers. 2. The sealing ring and the sealing ring are not tightly sealed. 3. The welding place of the ...

Adsorbent Media - Confidential Washington, D.C. Museum, USA - Case Study
THE PROBLEM: A confidential museum in Washington, D.C. tested its environment for harmful gases to see what could be potentially harming its artifacts. The results showed nitrogen dioxide (N02) and sulfur dioxide (S02) to be the main culprits testing at levels as high as 22.21 ppb and 1.68 ppb respectively. These levels of gases could cause irreversible damage to valuables in the museum over ...

On-line analysis of copper foundry’s stack gas composition by low resolution ft-ir gas analyser
ABSTRACT Stack gases of a copper foundry's after-burner were measured on-site by low resolution FT-IR gas analyser. Concentrations of carbon dioxide (CO2), carbon monoxide (CO), sulfur dioxide (SO2), nitric oxide (NO), nitrogen dioxide (NO2), methane (CH4) and water vapor (H2O) were continuously measured for a period of three days. Validation of the method included laboratory determination of ...

Treament of Hydrogen Sulfide (H2s)
This gas is often found in groundwater that contains iron and manganese. It is easily identified by its "rotten egg" odor. In addition to causing serious taste and odor problems, sulfide also promotes the growth of sulfur bacteria. Hydrogen sulfide can cause corrosion problems with iron and concrete pipes and reservoirs. Sulfides are formed by the anaerobic reduction of sulfates and organic ...

The Flakt-Hydro process: flue gas desulfurisation by use of seawater
ABB's seawater scrubbing process (the Flakt-Hydro process) for flue gas desulfurisation has recently triggered much interest among power producers because of its simple operating principle and high reliability. The process uses seawater to absorb and neutralise sulfur dioxide in flue gases. The absorbed gas is oxidised and returned to the ocean in the form it originated in the first place, namely ...

Function of SO2 gas leak detector
Summary: Sulfur dioxide (SO2) is a colorless transparent gas, is a toxic gas with a pungent odor. Can accelerate the corrosion process of most metals. In the presence of PM2.5, sulfite is dissolved in the solution, under which conditions sulfite is oxidized and then converted to sulfuric acid. In the traditional sense, this is the origin of acid rain. China is the world’s largest producer and ...

Evolution of marketable permits: the US experience with sulphur dioxide allowance trading
The Sulfur Dioxide Allowance Programme, created under Title IV of the Clean Air Act Amendments of 1990, is the first national market-based approach to environmental management employed in the United States and represents a radical departure from both the traditional regulatory approach to environmental policy and from previous emissions trading efforts. This paper reviews the goals of the SO2 ...
