  • 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 ...

  • 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 ...

  • Fire Codes: A Foundation of Safety for a Rapidly Changing World

    Chief among these safety features is fire protection. There are myriad codes and regulations relating to fire safety in commercial buildings, from standards on portable fire extinguishers to the installation of stationary pumps for fire protection — the U.S.- based National Fire Protection Agency (NFPA) alone has more than 300 consensus codes that have been adopted in whole or in part ...

  • Trace elements - controlling emissions from coal combustion

    International and national legislation is increasingly being applied to trace element emissions. Although emissions have decreased for a variety of reasons in many developed countries, continued use of coal and more successful control strategies in other sectors mean that coal combustion is still a relatively important source of some trace elements, especially mercury. Existing pollution control ...

  • Combustible Dust: It Doesn’t Take Much

    A dust accumulation of 1/32 of an inch deep—about the thickness of a dime—covering just five percent of a room’s surface area doesn’t sound like much, but it’s enough to cause a catastrophic explosion, according to the National Fire Protection Association (NFPA). Although good engineering and safety practices to prevent dust explosions have existed for decades, there ...

  • Application of combustion analyzers in safety instrumented systems

    The combustion process has always been considered having the potential for a hazardous event which could lead to personnel injury or loss of production. To mitigate this risk, the process industry is now implementing Safety Instrumented Systems which can identify hazardous operating conditions and correctly respond in such a way to bring the combustion process back to a safe operating condition ...

  • Combustion strategies for PFI hydrogen IC engines

    Hydrogen is a very interesting fuel when it comes to load control. The high flame speeds of hydrogen mixtures and its wide flammability limits permit very lean operation. Where possible, Wide Open Throttle (WOT) operation is used, which regulates the load with the mixture richness (qualitative control) instead of using volumetric regulation (quantitative control) and, thus, avoiding pumping ...
