  • The landfill gas collection, utilisation and surplus gas combustion acting in unison

    In landfill gas utilisation the basic task of the control system is to harmonise three completely independent processes. On the one hand, there is the gas production of the landfill which is inconstant. (From a price point of view, hardly worthwhile to store the gas in a gasometer) On the other side the independent gas utilisation process, which orientates itself to the requirement of the ...

  • Why high temperature combustion of landfill gas?

    Due to the accumulation of knowledge and the tightening of environmental law, the landfill technology has increasingly become concerned with the management of trace compounds in landfill gas. With landfill gas, contamination is through sulphur, chlorine, fluorine, halogenated hydrocarbons and heavy metals. Other trace elements such as volatile organic compounds (VOC), impose environmental ...

  • Case study - Natural gas production

    OVERVIEW The largest U.S.-based independent oil and gas producer and one of the largest independent processors of natural gas and natural gas liquids in North America was in search of new technologies to maintain the pollution control efficiency at their natural gas treatment facility. In typical gas plants, the well head natural gas needs to be treated to remove water, CO2, ...

  • The Goldilocks of Combustion Solutions

    It’s not too big, it’s not too small… It’s just right! We hear it all the time from our customers: “The ABUTEC 200 is too small for our site, but the HTF is too large. Can you create a custom unit?” The answer sometimes surprises those customers. While yes, we can certainly develop a custom unit just for your site, a more efficient (and cost-effective) ...


  • What do a brewery and a wastewater treatment facility have in common? More than you think

    You may think that a brewery and a wastewater treatment facility are about as similar as day and night, hot and cold, old and young. But they have more in common than you think. ABUTEC has worked with both to ensure their waste-to-energy systems function at top capacity. Bell’s Brewery in Kalamazoo, Michigan, needed a way to save money, ensure compliance and practice sustainability. ...


  • Influence factors of organic compounds leaching from PE pipes and the potential toxic effects on E. coli and rat C6 glioma cell

    Water quality safety is always a hot topic. Recently there has been a great increase in the use of polyethylene (PE) pipes in drinking water distribution systems in China. Some organics can leach from PE pipes into drinking water, which is undoubtedly harmful for consumers. In this study, potential organics leaching from two Chinese brands of PE pipe were investigated in order to determine the ...

  • Oxidative treatment of fentanyl compounds in water by sodium bromate combined with sodium sulphite

    As narcotic analgesics, fentanyl compounds have been commonly produced and widely used during surgical procedures. The residual and waste of fentanyl compounds have potential harmful impacts on the environment and human health. The oxidative degradation of fentanyl compounds by sodium bromate mixed systems was studied. Factors influencing the oxidation reaction, including molar ratio of ...

  • Modernising gas fired power plant boiler damper drives and damper bearings - Case Study

    Sector: Power Generation Category: Fluid Power Actuators, Services Products: PM/DM, Retrofit The challenge of modernising the instrumentation on an old utility boiler can be overwhelming, especially when the boiler was originally commissioned in 1964. Power utility base load preference has historically been the domain of the larger coal fired boilers. That has been the desired management ...

  • Asia`s Largest Oil and Gas Company Seeks to Lower its Own Rising Costs

    Growing demand and higher prices for natural gas might seem like good news for Asia’s largest oil & gas company. But for giant, Sinopec -- the world’s fifth largest company -- significant gas price increases in China also impact the cost of its own gas processing operations. That’s why engineers from the Sinopec Nanjing Engineering Company (SNEC) sought innovative ...

  • 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 ...

  • 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 ...

  • Exergy analysis of natural gas/DME combustion in homogeneous charge compression ignition engines (HCCI) using zero–dimensional model with detailed chemical kinetics mechanism

    In the present work, a single zone combustion model with detailed chemical kinetics is developed to study the effect of dimethyl ether (DME) concentration on the combustion of natural gas from second law point of view in a homogeneous charge compression ignition (HCCI) engine. The code can predict all exergy terms in the cylinder with crank angle during a closed cycle. The chemical kinetics ...

  • Prediction of partition coefficients for complex environmental contaminants: Validation of COSMOtherm, ABSOLV, and SPARC

    Prediction of partition coefficients is essential for screening of environmentally relevant compounds. Prediction methods using only the molecular structure as input are especially useful for this purpose. In the present study, we validated three prediction methods, COSMOtherm, ABSOLV and SPARC, which are based on more mechanistic approaches than most other quantitative structure activity ...

  • Compost biofiltration: an effective biological treatment system for treating volatile organic compounds from waste gas emissions

    Biofiltration, a simple technique involving microorganisms supported on a solid matrix, offers an attractive solution for the removal of volatile organic compounds (VOCs). The removal of benzene, toluene and xylene (model VOCs) in vapour phase has been compared individually in the present study using three biofilters. These biofilters were operated at different flow rates and concentrations ...

  • Influence of reference temperature on exergy and exergoeconomic performance of a natural gas fired thermal power plant

    The influence of reference temperature on exergy and exergoeconomic performance parameters of a thermal plant was investigated. The plant was simulated using HYSYS (2003) process simulator software and the exergy and exergoeconomic analyses were done using Microsoft EXCEL spreadsheet. As reference temperature increased from 15°C to 35°C, exergy efficiency decreased from 11.7% to 11.5% and ...
