  • Controlling acid gas mists

    Gas cleaning New and strict pollution regulations in metallurgical plants worldwide are restricting particulate and acid gas emissions to extremely low levels. Because of that, sulphuric acid plants are being installed to remove and utilise S02 in gases resulting from the roasting of sulphide ores, smelting of ores, and burning or regeneration of spent acid or acid sludge from ...

  • Cleaning the Air We Breathe, Coal Fired Power Plant - Case Study

    By cleaning flue gases from coal power plants, the amount of environmentally hazardous emissions can be sharply reduced. Mist elimination from Munters is a critical part of this process. Munters has worked with leading power generating companies for decades and have through testing and follow up built an extensive parameter database and design tool to be able to adapt and optimize results based ...

  • Least-Cost Approaches to Reducing Acid Emissions

    ' The costs of meeting sulfur emission targets can be high. It is essential, therefore, that countries adopt policies which (a) minimize the net economic and social costs of reducing emissions to the agreed target levels, and (b) maximize the overlap between measures designed to reduce acidifying emissions and those addressing other forms of air pollution. This note discusses alternative ...

  • Two Detector Solution to Analyzing Sulfur

    Sulfur compounds are reactive, corrosive to pipes, and destructive to catalysts in petroleum refineries. Sulfur emission are strictly regulated globally. When released into the atmosphere sulfur dioxide converts to sulfuric acid resulting in adverse effects on human health and the environment. Sulfur detection is found useful in many other industries; therefore, detection of sulfur compounds in ...

  • Environmental Effects of Acid Rain

    Air Pollution Creates Acid Rain Scientists have discovered that air pollution from the burning of fossil fuels is the major cause of acid rain. Acidic deposition, or acid rain as it is commonly known, occurs when emissions of sulfur dioxide (SO2) and oxides of nitrogen (NOx) react in the atmosphere with water, oxygen, and oxidants to form various acidic compounds. This mixture forms a mild ...

  • Gas turbine compliance emissions test case study

    CKwas retained by Lake Road Generating Company, LP (Lake Road) to conduct a compliance emissions test program on three combustion turbine and heat recovery steam generators (CT/HRSG). The purpose of this program is to demonstrate that emissions from the CT/HRSGs are within the emission limits specified in the operating permit issued by the Connecticut Department of Environmental Protection ...

  • SULFURIC ACID PLANT TAIL GAS CLEANUP WITH CANSOLV“ SYSTEM SO2 SCRUBBING TECHNOLOGY

    The tail gas from a single absorption sulfuric acid plant typically contains 2000-3000 ppmv of unreacted SO2. Emission regulations for new plants in most jurisdictions today require cleanup of this stream prior to discharge into the atmosphere and many grandfathered units are being required to decrease emission levels. The current paradigm is to add a second stage of conversion, which reduces the ...

  • Case study - Purified terephthalic acid plant

    Overview A major chemical manufacturer required a pollution control system to destroy the halogenated volatile organic compounds (VOCs) emitted during the formulation of Pure Terephthalic Acid (PTA). During the production process, methyl bromide is converted to hydrogen bromide. The pollution control system had to be designed to withstand the corrosiveness of the hydrogen bromide and ...

  • Reducing Odor and VOC Emissions

    The Montgomery County Regional Composting Facility (MCRCF) in Silver Spring, Maryland is designed to process 400 wet tons/day of lime amended biosolids from the Blue Plains Wastewater Treatment Plant (WWTP) in Washington, D.C. Recently, political pressures forced operations to cease at the MCRCF. Although the aerated static pile composting plant’s fate has not been completely decided, its owner, ...

  • Extensions to the emission trading system in Spain

    Climate change is the subject of debate these days derived from the Copenhagen Summit, where the major commitments and agreements have been discussed. In any case, the commitment within the EU is strong and clear for the immediate future. The commitments to reduce emissions of greenhouse gases within the EU framework have as their main flagship the Emission Trading System (ETS) regime established ...

  • Renewable energy in chemical industry – the case of formic acid production

    This paper analyses the economical viability of replacing fossil energy by renewable sources by taking CO2 emission legislation into account. A single chemical industry case, formic acid production, is studied in a tangible manner to provide a concrete example for industrial managers and legislators. The practical case was supported by examining scientific and other databases. This study ...

  • Turning Carbon Emissions Into A Revenue Stream

    On the heels of the EPA’s new carbon rules proposed by President Obama on June 2, I wanted to take a closer look at a potential disruptive technological breakthrough: taking CO2 waste streams and turning them into saleable, value-added feedstocks. Certainly, the deployment of renewables, energy efficiency, smart grid, and energy storage technologies offer some of the most cost-effective ...

  • A cure for Environmental Emissions case study

    Disposing of nearly 1 million pounds of medical waste a month is no easy task. The wet electrostatic precipitator, installed at Rochester, MN-based Mayo Clinic, seems to be just what the doctor ordered. While the medical waste incinerator at Mayo Clinic in Rochester, MN, consistently met state and federal emission requirements, facility leadership recognized that installing a wet electrostatic ...

  • Application of the EU Emissions Trading Directive

    Synthesising Member State reporting on the ETS The European Union (EU) emissions trading system (ETS) is one of the key climate policy instruments implemented in the EU to achieve its emission reductions objectives in a cost‑effective manner. The EU Emissions Trading Directive (EU, 2003, referred to hereafter as the 'EU ETS Directive'), and in particular Article 21 ...

  • Acid Rain Program: SO2 Allowance Trading System Fact Sheet

    The innovative, market-based SO2 allowance trading component of the Acid Rain Program allows utilities to adopt the most cost-effective strategy to reduce SO2 emissions at units in their systems. The Acid Rain Program operating permit outlines the specific program requirements and compliance options chosen by each source. Affected utilities are also required to install systems that continuously ...

  • Emissions Trading - Ontario sets out emissions trading plans

    Canadian province of Ontario has issued a discussion paper proposing a hybrid emissions trading scheme covering nitrogen oxides and sulphur dioxide. Elisabeth DeMarco examines the plans for a scheme that could form the basis for a wider emissions trading system. Ontario sets out emissions trading plans In late March, the Ontario Ministry of the Environment (MoE) released a policy option paper, ...


  • Hydrocarbon evaporative emissions & control for automotives

    Even the cleanest and most efficient vehicle on the market today still pollutes the air and otherwise damages the environment. Motor vehicles emit several noxious pollutants which vehicle emissions standards are designed to regulate. Vehicles generally emit Hydrocarbons (HC), Carbon monoxide (CO), Nitrogen oxides (NOx) and Fine airborne particulate matter (PM) as pollutants that require control. ...

  • Modeling emissions from offshore drilling

    To regulate drilling activities proposed by oil and gas companies in the oil-rich Gulf of Mexico (GOM), governing agencies require the submittal and approval of certain plan documents before drilling activities can be initiated. For drilling activities in the Western GOM, these plans typically consist of one of the following: EP, or Exploration Plan – required to conduct ...

  • New fertilizer industry gas cleaning technology achieves lower required emission levels

    All fertilizer plants produce dust and gases, such as ammonia (NH3) and acid fumes, which must be removed at very high efficiencies before venting to atmosphere. Familiar examples are granulation and prilling of nitrogenous products such as Urea which is the most widely used fertilizer in the world(1). Phosphatic fertilizer production produces dust and Fluorine compounds. Typical air treatment ...
