  • LED Applications for Oil and Gas Refining and Processing

    Oil and gas processing facilities are unsafe due to the existence of hazardous compounds during operations. When addressing such issues, companies in the sector may deploy explosion proof lighting systems to prevent the ignition of sparks created from the electrical equipment. The adoption of LED technology in oil and gas refineries has helped reinforce key safety measures associated with ...

  • Monitoring Gas Emissions from Volcanoes to Predict Volcanic Activity

    To understand and predict the behaviour of volcanoes an increasing number of scientists are combining geological monitoring and geochemical models. By measuring and monitoring the prevalence of gases like CO2, scientists hope to be able to better predict the likelihood of volcanic eruptions. In 2010 Iceland’s Eyjafjallajökull volcano erupted, releasing 250 million ...

  • 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 ...

  • What`s the Best Air Pollution Control Technology for My Process?

    Air pollution control equipment is not something that business owners address by saying, “Let’s do the right thing for the environment and install an oxidizer!” In fact, the scenario is more likely to be “We need to increase productivity (always a good thing!), but that will put us over our annual emissions limits. Do we know what we will need? Where do we start? Who can ...

  • Treatment and Disposal of Air Pollution Control Residue

    What is APCr? Thermal waste management using Energy Recovery Facilities (ERFs) is now a well-managed and mature technology that is subject to environmental monitoring by a range of competent international bodies. These ERFs have been established as a means of diverting waste away from landfill disposal and for valorising the material and energy content of the waste. Counter to historic ...

  • Acid mine drainage treatment

    Acid mine/rock drainage is a rampant problem in the world today. The above photo depicts acid drainage at an abandoned mine in the Yukon Territory of northwest Canada. This mine shares a similar history to thousands of other mines throughout the world. It was in operation for six short years in the 1950’s, producing gold ore. Its profitability eventually failed and it was abandoned. In the ...

  • 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 ...

  • Amerada Hess - acid flow back

    Client: Amerada Hess Triton - UK CETCO Oilfield Services successfully treated contaminated water returns on the Amerada Hess Triton FPSO. The fluids were treated during well clean-up operations and have reduced the potential for overboard oil discharges and production upsets at the offshore installation approximately 120 miles east of Aberdeen. Contaminated water returns are a common problem for ...

  • Rehabilitation of Hydrogen Grooving in Sulfuric Acid Line

    Around October 2001, one of the major petrochemical refineries located on the Texas Louisiana Gulf coast needed to rehabilitate 6' and 8” diameter “fresh acid” (98% sulfuric acid) lines. Such lines tend to suffer from internal gouging due to formation of hydrogen gas in voids, which are caused by turbulence at directional changes in the pipe flow such as elbows, etc. This is a natural event, ...

  • 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 ...

  • Adsorptive removal of methylene blue by CuO-acid modified sepiolite as effective adsorbent and its regeneration with high-temperature gas stream

    In this study, the dynamic adsorption of methylene blue dye onto CuO-acid modified sepiolite was investigated. Meanwhile, the equilibrium and kinetic data of the adsorption process were studied to understand the adsorption mechanism. Furthermore, a high-temperature gas stream was applied to regenerate the adsorbent. The results showed that the Langmuir isotherm model was applied to describe ...

  • Understanding the atmospheric measurement and behavior of perfluorooctanoic acid

    The recently reported quantification of the atmospheric sampling artifact for perfluorooctanoic acid (PFOA) was applied to existing gas and particle concentration measurements. Specifically, gas phase concentrations were increased by a factor of 3.5 and particle‐bound concentrations by a factor of 0.1. The correlation constants in two particle–gas partition coefficient (KQA) estimation equations ...

  • 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 ...

  • Development of headspace–gas chromatography–flame ionization detection procedure to determine volatile fatty acids in zoo organic waste leachates

    In order to determine volatile fatty acids (short chain monocarboxylic acids with 2 to 6 carbon atoms in a molecule) in leachates formed in organic waste piles a procedure based on static headspace (HS) coupled with gas chromatography (GC) have been proposed and optimized. The conditions of HS extraction and sample introduction into a gas chromatograph as well as of chromatographic separation ...

  • 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 ...
