  • Reduced Emissions for Landfill Gas Installations

    The use of landfill gas as a source of renewable energy is increasing. For environmental and safety reasons, the owners of the waste storage sites have to strictly monitor and control the construction, operations, and emissions generated. Sulzer offers solutions to control these emissions within the limits given by the government. Landfill gas is similar to natural gas, but it is created by ...

  • Putting a Lid on Catalyst Issues

    While it is a given that emissions control technology must first and foremost remove harmful constituents from the engine exhaust gas stream, it is equally true that they must also be able to operate in the real world, where durability, reliability and serviceability are critical. It was with those facts in mind that DCL International Inc., the Concord, Ontario, Canada, supplier of advanced ...

  • Advanced Threeway Catalysts

    One area of catalyst system design which has received relatively little attention is the method of application of precious metal, specifically with regard to its positioning in the catalyst. Recent advances in catalyst coating technology have enabled both washcoat and precious metals to be distributed inhomogeneously (zoned) along the length of a catalyst monolith. With the option of zone coating ...

  • Case study - Catalytic oxidizer catalyst replacement

    Overview A New Jersey pharmaceutical company purchased a thermal incinerator to treat the heptane and hexane exhaust from their capsule wash system. The thermal incinerator"s "tubular" design was modified with a catalyst bed in order to reduce the system"s operational costs. Unfortunately, when operating in the catalytic mode, the oxidizer failed to provide the required ...

  • Controlling Pharmaceutical Coating & Drying Process Emissions

    Capturing and destroying harmful emissions from pharmaceutical processes can be challenging. It’s not because the volatile organic compounds (VOCs) are difficult to destroy using catalytic or thermal techniques. It’s because their concentrations can be so high. These process streams raise safety concerns, both when they’re collected in vents and when they reach the final ...

  • Case study - Kiln emission control technologies

    Overview A specialty ceramic material manufacturer in the United States operates several custom-built furnaces in their manufacturing process.  Sometimes referred to as kilns, these high-temperature process devices are generally a major source of air pollutants and require an abatement technology to meet environmental regulations with the state or federal agencies.  As is the ...

  • The Effect of Phosphorus and Boron Lubricant Oil Additives on Catalyst Durability

    With ever-tightening legislation driving down emissions limits, minimisation of catalyst deactivation is very important. Attention has now focused on chemical poisoning of three-way catalysts (TWC) by elements commonly found in engine oil. ...

  • Recovery of Precious Metal Catalysts - A New Process Using Supercritical Water Oxidation

    Up to now, the recovery of precious metals used as catalysts in chemical processes has involved the use of incineration. Now, however, a British-Swedish joint venture has developed a process which uses supercritical water oxidation instead, which provides many economic and environmental advantages. Precious metals are used extensively in catalysts in a wide range of industrial chemical processes. ...

  • Case study - Rubber curing emissions

    Overview A rubber curing company was looking for a new, affordable abatement solution to treat their blue haze and low-level Volatile Organic Compounds (VOCs) in order to meet regulatory requirements. The large Electrostatic Precipitator (ESP) in use was extremely expensive to operate and maintain. The company began their search for a system that offered effective opacity control and ...

  • Global innovation vs. local regulation: introduction of automotive emission control in Sweden and Europe

    The increasing effects of pollution in larger cities in Europe in the 1960s spurred investigations into the sources of pollution and the means for its reduction. One important source of pollution was found to be the increasing fleet of passenger cars. In difference to a common description like "strict vehicle emission regulations were established in EU and EFTA countries in 1995", this paper ...

  • Case study - Styrene emissions: Catalytic oxidizer with concentrator

    Overview The world's largest button manufacturer needed a pollution control system that would destroy styrene emissions from a variety of plant processes. The plant was proactively seeking a cost-effective air pollution control solution to preempt future regulatory action. The main concern of the customer was the high operating cost of an emission control system. ...

  • 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 ...

  • Recovering Valuable Chemicals from Air Emissions

    Air emissions in many cases are a waste of valuable natural resources that should have become useful chemicals. In some cases the economic payback from recycling/reuse of air emissions can be almost as much a motivation to control air pollution as government regulations. Examples of recycling and reuse of air emissions are sulfur oxides emissions that can be made into sulfuric acid, cement ...


  • Air Pollution Control Specs

    As the full effect of the federal Clean Air Act (CAA) Amendments continue to impact today‚Äôs industry, many companies will be required to install new or additional air pollution control equipment.  With more than 25 years of proven success in a variety of industries, catalytic and thermal oxidation has become a popular method for controlling volatile organic compound (VOC) and hazardous air ...
