  • Meeting emission control through improved actuation

    Introduction Reducing fugitive emissions, particularly methane, is a major priority in the fight against climate change. Although valves and actuators have been the focus for reduction efforts because valve leakage accounts for more than half of total fugitive emissions, the problem is mainly old valves that weren't designed using the latest materials and technologies. New technologies can ...

  • Cemex plant Ruedersdorf - Case Study

    CEMEX Deutschland AG is one of the biggest producers of ready-mixed-concrete, cement and minerals. In Germany CEMEX employs a staff of approximately 3,200 people and is part of the International CEMEX Group with a head count of 50,000. After the German re-unification the Company acquired the existing cement plant in Ruedersdorf. Investments to save CEMEX invested ...

  • 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 - ETO sterilizer abatement

    OVERVIEW Product sterilization companies are generally required to utilize a pollution control device for treatment of exhaust gases from their aeration room and sterilization chambers.  In the United States, they need to be in compliance with NESHAP (National Emission Standards for Hazardous Air Pollutants) regulations that dictate a 99% destruction efficiency of EtO (Ethylene ...

  • Case study - Paint booth over spray

    OVERVIEW A major automotive component supplier needed to control the emissions from its paint spray process. The plant emissions had characteristics common to many paint spray plants: high air flow, low volatile organic compound (VOC) concentration and particulate. The company needed an emission control solution that had low operating costs and that could also fit in their limited ...

  • Case study - Carbon fiber: Oven emission control strategies

    OVERVIEW Carbon fiber (fibre) and graphite reinforced polymers are materials that have, and will continue to revolutionize the products we use everyday by making them stronger, lighter and more durable. However, the manufacturing process can have serious environmental ramifications and immediate danger to human health if careful consideration is not given to emission control at the ...

  • Case study - Fiberglass polymer emissions: RTO control technology

    OVERVIEW A producer and supplier of corrosion resistant piping systems was looking to improve the reliability and lower operating expenses of an existing air pollution control system at their facility. During their manufacturing process, centrifugally cast mortar pipe systems are reinforced with a fiberglass polymer. This makes the pipe ideally suited for most corrosive piping ...

  • 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 ...

  • 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 ...

  • Chemical Industry: Sale of by-Product HCl Covers Cost of Emission Control System Problem Case Study

    Some of the specialty chemical processes at a major chemical manufacturer’s plant result in considerable HCl loading in the off-gas. The HCl must be removed before the off-gas can be discharged to the atmosphere. Production of saleable by-product HCl solution was an important goal when looking for a high-efficiency HCl removal system. The company wanted to achieve a very low level of ...
