  • The importance of maintaining your fixed gas analyser

    Plant technicians rigorously check for contaminates within the digester and ensure that the performance is optimised but maintaining the gas analyser monitoring the whole process is often overlooked.  Many analysers are used in harsh and potentially explosive environments and so it is of paramount importance that the operation runs smoothly and safely. With simple maintenance of your ...

  • Fixed Versus Portable Gas Detection – Which Is Better?

    Did you know that workers are needlessly injured every year as a result of leaking toxic or combustible substances? Such incidents are known to involve a wide range of hazardous gases (including ammonia, carbon monoxide, chlorine, hydrogen sulfide, hydrocarbon vapors and so on). The sad reality is that most of these accidents are avoidable if only the workplace is adequately monitored. This leads ...

  • Fixed price contract versus incentive–based contract in the oil and gas industry

    The research question of this paper is to analyse when an operator and a service provider prefer a fixed price contract, common in the oil and gas industry, versus the uncommon incentive–based contract. The contracts are modelled with 20 parameters and one free choice variable which is the time to complete the project determined by the service provider. The method is to determine the ...

  • Preliminary studies of lignocellulosics and waste fuels for fixed bed gasification

    This study was carried out to understand the decomposition behaviour of a range of biofuel and waste feedstock during gasification in a downdraft gasifier. A laboratory scale large sample thermogravimetric analyser (LSTA) is used which allows the data on burn-out characteristics of different fuel particles to be measured under agitated conditions. The conditions chosen simulate the combustion ...

  • Comparing TGA, FTIR and fixed filter infrared analyzers for measuring soot levels in in-service lubricants

    Measuring soot in diesel engine oil has become more important as soot levels get higher due to exhaust gas recirculation. As soot isone of the key indicators for the condition of the oil, diesel engine maintenance programs performing regular soot checks can realize cost savings by extending drain periods and reducing used oil disposal. TGA (Thermal Gravimetric Analysis) is the traditional method ...

  • Case study - Monitoring landfill gas

    Infrared absorption Infrared absorption is usually the preferred method for measuring methane and carbon dioxide. Most gases absorb radiation in the infrared region. The wavelength of radiation that is absorbed is determined by the natural vibration frequencies of the molecule. These natural frequencies will depend on several factors. Thus different gas molecules have different natural ...

  • Danger and Detection of Hydrogen Sulphide Gas in Oil and Gas Exploration and Production

    A rig worker smells rotten eggs near the well head, rubs his itchy eyes as he investigates the frosty pipe connections. After a few moments, he believes all is fine as he no longer smells the tell-tale hydrogen sulphide odour. In this scenario, we can only hope the worker recognises the danger and quickly leaves the site. Oil fields, especially mature ones, can produce hydrogen sulphide gas ...

  • Thermodynamic and economic assessments of gas turbine inlet air-cooling by evaporative technique

    In this study, the effects of gas turbine inlet air-cooling by evaporative technique on work output and thermal end exergy efficiency were analysed. These analyses are performed with the use of per unit volumetric flow, which is fixed regardless of atmospheric air conditions. In addition, a simple and effective model is developed for the economic analysis of evaporative cooling. As a case study, ...
