  • 5th-Generation Thermox WDG Flue Gas Combustion Analyzer

    "For more than 40 years, we have been a leader in combustion gas analysis," says Mike Fuller, divison VP of sales and marketing and business development for Ametek Process Instruments, "and we believe the WDG-V is the combustion analyzer of the future." WDG analyzers are based on a zirconium oxide cell that provides a reliable and cost-effective solution for measuring excess oxygen in flue gas as ...

  • AMETEK THERMOX Introduces the WDG-V Combustion Analyzer

    Abstract AMETEK THERMOX Introduces the 5th Generation THERMOX Combustion Gas Analyzer in a CONTROL Magazine Exclusive. WDG analyzers are based on a zirconium oxide cell that provides a reliable and cost-effective solution for measuring excess oxygen in flue gas as well as CO and methane levels.  Information from the Gas Analyzer allows operators to obtain the highest ...

  • 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 ...

  • Measurement of Oxygen in CO Boiler of FCC Process – Case Study

    Background Fluidized-Bed Catalytic Cracking (FCC) is the most important and widely used refinery process for converting low value heavy oils into more valuable gasoline and lighter products. Application Description The catalyst is covered with carbon (coke) from the cracking reaction which lowers its activity. Therefore, the catalyst is fed to the ...

  • SITRANS SL in-situ analyzer saves cost for a steel plant replacing existing extractive setup – Case Study

    The customer Steel industry plants all over the world have multiple processes, most of them emitting CO and CO2 in very high concentrations (tens of %). CO is used as a combustible due to its high calorific value. It is stored in a huge tank before it is used by the power plant next door. CO in such high concentration is explosive in presence of a few molecules of oxygen. Therefore, ...

  • The Other Side of Zirconium Oxide case study

    Regular Fuel Efficiency Applications Separate Oxygen and Combustibles Sensors In standard flue gas applications for Thermox analyzers, the user generally tries to extract the maximum energy from the fuel and transfers as much of that energy as possible to the process. These applications require the process to be operated as efficiently as possible by keeping both oxygen (excess air) and ...

  • Fenton degradation of Cartap hydrochloride: identification of the main intermediates and the degradation pathway

    The advanced oxidation of Cartap hydrochloride (Cartap) promoted by the Fenton system in an aqueous medium was investigated. Based on total organic carbon, chemical oxygen demand and high-performance liquid chromatography, the oxidation of Cartap is quite efficient by the Fenton system. Its long chain is easily destroyed, but the reaction does not proceed to complete mineralization. Ion ...

  • Monitoring Air/Fuel Mixtures in Glass and Glass Fiber Manufacturing case study

    Measurement of Premix Gas. To produce the desired flame in a glass forehearth or when making fiberglass (glass fiber) insulation, an air/fuel pre-mixer is used. The pre-mixer combines compressed natural gas or propane with air and this mixture is then piped to the process burners At the burner, a fuelrich or fuel-lean flame is produced depending on the air/ fuel ratio selected. In many ...

  • Combustion optimization by fast excess air control – Case Study

    Combustion is the conversion of primary chemical energy contained in fuels into heat through the process of oxidation at high temperatures. The oxygen required for the combustion is supplied as part of the combustion air that is fed to the process. In ideal (stoichiometric) combustion the amount of oxygen supplied to the process is just sufficient to burn all combustibles completely. In real ...

  • Facilitating compliance with consent decree requirements using an EMIS

    In late 2008, T3, a division of Trinity Consultants, developed an environmental management information system (EMIS) to manage “near real-time” emissions data at a petroleum refinery. The system is designed to support Consent Decree requirements for compliance demonstrations with air quality regulations at the facility. Functionality delivered includes advanced data gathering, ...

  • Checklist for Boiler Maintenance

    Boilers play a crucial role at industrial facilities and it is imperative that they be safely and properly maintained. Routine boiler maintenance can help prevent unplanned shutdowns and outages, increase the efficiency of the boiler and cut operating costs, and ensure that the facility is in full compliance with all laws and regulations governing boiler safety. What follows is a boiler ...

  • Navigating NSPS subpart Db for boilers: a case study

    Over the past year, Trinity assisted a chemical company with the permitting and installation of a new 220 MMBtu/hr package boiler. The new natural gas-fired boiler replaces coal-fired units that were installed in the 1940s. Navigating through the numerous, and at times conflicting, regulatory requirements applicable to such a unit has been challenging. With careful planning and implementation, ...
