Control of malodors using Ecosorb - A natural product
Abstract Ecosorb removes many malodors, including sulfur dioxide, hydrogen sulfide and ammonia, from the environment. It is made up of a combination of essential oils consisting of an equilibrium of neutral organic compounds and organic buffers. Its pH ranges from 4.0 to 6.8. Acidic malodors such as hydrogen sulfide and sulfur dioxide are removed by at least four mechanisms including ...

How to deal with liquid sulfur dioxide leakage?
We all know that sulfur dioxide is a chemical substance and is harmful. Therefore, when dealing with sulfur dioxide, it needs to be protected in all directions. What if sulfur dioxide leaks? Let Xiaobian come to answer your questions. When the liquid sulfur dioxide leaks, it is necessary to quickly evacuate the personnel in the contaminated area to the upwind, and then immediately isolate it. ...

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 ...

Pulp & Paper: Great Northern Uses Venturi Scrubbers - Case Study
The Great Northern Paper Co.’s mill in Millinocket, Maine, produces about 500,000 tpy of paper for telephone directories, magazines, almanacs, business forms, catalogs, and school workbooks. Pulp is produced in the form of chips, using the sulfite chemical process. The chips are cooked in a magnesium bisulfite solution in batch digesters at specific temperatures and pressure. When the ...

SO2 gas sensor - Sulphur Dioxide Detector
Sulfur dioxide detector is a gas sensor that uses the SO2 sensor probe to detect the concentration of SO2 gas in the air environment. Constant monitoring of gas concentration and flameproof design. A sulfur dioxide detector can be configured with a single controller, or multiple devices can be configured with one or more hosts. At the same time through the SO2 sensor multi-point centralized ...

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 ...

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 ...

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 ...

CANSOLV® SULFUR DIOXIDE SCRUBBING SYSTEM
The CANSOLV® System scrubbing technology is the leading regenerable SO2 scrubbing process. It uses an aqueous amine solvent in a conventional amine treater process flowsheet configuration to achieve high-efficiency removal of SO2 from a large variety of gas streams. The technology is applicable to petroleum refining, natural gas sweetening, smelting of sulfide ores, power generation, pulp ...

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 ...

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 ...

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 ...

Plantwide Applicability Limits (PALs): A Legitimate Alternative to Major New Source Review Permitting
Plantwide Applicability Limits: A Legitimate Alternative to Major New Source Review Permitting. There have been a number of recent developments regarding U.S. EPA"s interpretation of the major New Source Review (NSR) air permitting rules that are related to the NSR Reform provisions of December 2002. When these new interpretations are considered in combination with the promulgation of new, more ...

Environmental impact of using biodiesel as fuel in transportation: a review
The environmental pollution and global warming associated with the use of fossil fuels, has forced a search for alternative fuels in transportation. This paper presents a review of the use of biodiesel in CI engines and its environmental impacts. There is a significant reduction in the emission of unburned hydrocarbons, polyaromatic hydrocarbons and soot, particulate matters, carbon monoxide, ...

Analysis of Natural Gas Products by GC / TCD / FID
The complex mixture of condensible hydrocarbons and permanent gases in a natural gas product has historically been separated on gas chromatographs equipped with dual columns and a switching valve. The light gases are separated from heavier compounds on a molecular sieve column, which is then backflushed onto a suitable column to separating the rest of the mixture. The Buck Scientific ...
