  • 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 ...

  • Peroxy-acid treatment of selected PAHs in sediments

    In an attempt to address some of the disadvantages of the common biotic and abiotic processes used for the degradation of Polycyclic Aromatic Hydrocarbons (PAHs), an alternative strategy utilising a primary chemical oxidative step to be combined with a biological post-treatment step was created. The degradation of α-methylnaphthalene, fluorene, phenanthrene, anthracene, pyrene and ...

  • Repair, retrofit, and rebuild services for amine treating acid gas process - Case Study

    Catalytic Products International (CPI) was recently engaged by a Western Colorado Gas Processing Facility to review the existing amine treating acid gas process and the air pollution control equipment installed in an effort to help optimize the units and make improvements to the reliability of the entire system. Introduction: Identify root cause of numerous failures and create an ...

  • Case study - Oil and gas production

    Problem The largest U.S.-based independent oil and gas producer and one of the largest independent processors of natural gas and natural gas liquids in North America was in search of new technologies to maintain the pollution control efficiency at their natural gas treatment facility. In typical gas plants, the well head natural gas needs to be treated to remove water, CO2, any ...

  • Microbial control reduces sulfide

    The article is about sewage odour control using a totally NEW technology known as Microbial Control. Microbial control treats the cause of sewage odour, corrosion and methane gas production in sewers by removing the biofilm / sediment (slimes) complexes where sewage odour and methane gas are produced. Without sewage odour you cannot have sewage infrastructure corrosion from sulfuric acid. As ...

  • Case study - Natural gas production

    OVERVIEW The largest U.S.-based independent oil and gas producer and one of the largest independent processors of natural gas and natural gas liquids in North America was in search of new technologies to maintain the pollution control efficiency at their natural gas treatment facility. In typical gas plants, the well head natural gas needs to be treated to remove water, CO2, ...

  • Case study - Reactor vent emission control

    OVERVIEW Many chemical and petroleum companies use batch reactors to make their products.  These reactors typically have vents which are opened and closed during emptying, filling, mixing, heating or cooling and other steps of the production process.  The gases coming from these vents must be controlled under most government regulations.  Generally speaking, 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 ...

  • Innovative wet electrostatic precipitators assure competitive edge in acid marketplace

    The unsteady global economic recovery continues to subject many core industries to persistent volatility in profits, prices, markets and capital investments. However, some analysts remain optimistic about the global international trade in sulfur in all forms, particularly sulfuric acid. This versatile mineral acid is both the world’s most widely used chemical, and the one with the highest ...

  • Mercaptan odor control - case study

    Background In municipal and industrial waste treatment, hydrogen sulfide is not the only offensive gas generated from anaerobic decomposition. Mercaptans (RSH) are the organic equivalent to hydrogen sulfide and more odorous at 1/1000th the concentration. Mercaptans are naturally occurring from the degradation of sulfur containing organics (proteins, etc.).   A table of ...

  • 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 ...

  • Air pollution control using laser analysis – Case Study

    An LDS 6 analyzer monitors HF emissions during the production of hydrofluoric acid in accordance with the German Technical Instructions on Air Quality Control (TA Luft) The customer Fine chemicals and inorganic basic chemicals have been developed and produced at the Seelze chemical site in northern Germany for more than 100 years. Such a basic chemical is ...

  • Case study - Amine tail gas treatment

    COVERING YOUR TAIL GAS The discovery of new shale formations throughout the world and the development of new drilling technologies have increased natural gas production and prompted government agencies to instigate tighter air-pollutioncontrol regulations on processing operations. Unfortunately, meeting environmental regulations is not a profit-generating endeavor. Simply put, the time ...

  • 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 ...
