  • Determining flammability of SpillFix Universal Organic Absorbent

    SpillFix Universal Organic Absorbent is an industrial absorbent product made from natural coir (coconut husk). Flammability tests (as detailed below) have determined that the product is a Not Readily Combustible Solid, and is unlikely to catch fire even after absorbing flammable spills. Determining Flammability The tests for determining ...

  • Mathematical modelling of flue-gas desulphurisation using lime slurry in a turbulent contact absorber

    A mathematical model has been developed for absorption of SO2 from flue gases using lime slurry in Turbulent Contact Absorbers (TCA). In this model, the TCA was simulated by considering it as a falling film absorption system. Turbulent effects were taken into account by using eddy viscosity and eddy diffusivity. The system of partial differential equations of mass transfer with moving boundaries ...

  • The study of radon levels and absorbed dose in the staff and visitors of Alisadr Cave

    CR-39 passive integrating Solid State Nuclear Track etch Detectors (SSNTDs) were used to measure atmospheric radon concentrations in the Alisadr show cave in Hamedan province, Iran. This was done in order to assess the risk from natural environmental radiation to tourists and cave guides. The study was carried out in 12 locations in the winter and spring periods. The mean radon concentration ...

  • Replacement of Two Separator /Absorber Units at an Acid Regeneration Plant

    If professional engineers were asked to define a perfect world, their answer would no doubt include projects that were blessed with a clear and precise description of the requirements, a viable schedule, availability of materials, and a reasonable amount of design freedom. Of course there is no perfect world, so engineers must work with restrictions that vary from difficult to almost impossible. ...

  • Does shale gas mean cheap gas?

    What is the true impact of shale gas extraction in the UK? Swathes of the British population are against fracking (the process of releasing natural gas trapped within shale rock formations) due to its perceived visual impact and environmental concerns. Two out of three of the main political parties apparently support further exploration and ...

  • Gas Safety in Confined Spaces

    Introduction An offshore worker ensures a vessel is safe to enter; a plant manager enters a small plant room; a contractor inspects the lining of a sewage pipe.  All these personnel face common dangers, despite working in widely different industries.  Gas-related injury poses a serious threat in any confined space where the free movement of air is limited. A confined space ...

  • Gas safety in confined spaces

    An engineer repairs buried cables; a plant manager enters a small plant room; a contractor inspects the lining of a sewage pipe.  All these personnel face a common danger, despite working in widely different industries.  Gas-related injury poses a serious threat in any confined space where the free movement of air is limited.  ...

  • 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 ...

  • Chlorine gas protection - Case Study

    Application As part of a scheme to bring safe drinking water to 1.5 million people in Omdurman City, part of Greater Khartoum, Biwater International was appointed by the Government of Sudan to undertake a major turnkey design and construction project. Chlorine is the conventional means of water disinfection, so Biwater brought in ERG to design and manufacture the emergency gas ...

  • Gas detector communication technology for offshore oil and gas platforms

    In few applications is safety as important as on offshore oil and gas platforms. Explosive hazards from hydrocarbon gases and vapours are an ever-present risk, whilst toxic hydrogen sulphide gas and depleted oxygen environments can pose significant risks to personnel. Gas detectors are therefore essential to provide dependable early warning of gas hazards. Gas detectors are permanently installed ...

  • Laser gas detection is now cheap, fast and reliable

    Laser based gas detectors are now being used in a wide variety of applications for process and quality monitoring, and safety and environmental compliance. The reasons are that laser detectors are more reliable and less expensive than alternative solutions. Laser detectors combine semiconductor tunable diode lasers (TDL) and optical fibres developed by the telecommunications industry with ...

  • Upgrading from Pellistor Gas Sensors to Infrared Technology

    In this article Andy Avenell, Crowcon’s Fixed Systems Product Manager, considers the shift towards infrared (IR) gas sensor technology in the oil and gas industry. Abstract Flammable gases and vapours can present considerable dangers in many industrial applications, none more so than the processes involved in extracting, transporting and processing oil and gas. Fast and reliable ...

  • Italy Oil and Gas Report Q1 2013

    Aside from the country’s well-publicized economic woes, Italy is at a crossroads in terms of energy market development. The public has rejected state efforts to revive its nuclear strategy, leaving the way clear for gas volumes to rise steadily higher – forcing the import bill up at the same pace. Domestic oil and gas volumes are significant, with some upside potential, while ...


  • Oil refinery vapour gas case study

    1.0 Evaluation of Refinery Gases Various refinery gases are generated in the process of oil refining. These vary, depending upon the type of crude oil being distilled, such as Reduced Crude distillation, or Naphtha cracker. For the purposes of this case study the description and range of refinery gases are those gases produced from refining Crude Oil and Reduced Crude only. Crude ...

  • Detecting Hydrogen Gas and Fires: Seeing the Unseen

    Hydrogen usage is growing. The general public sees and reads about hydrogen as an alternative fuel for cars. However, the big use for hydrogen is found in hydrocarbon processing and other important manufacturing processes. Hydrogen is the first element on the periodic table and is an essential element in the manufacturing of many of our everyday products. We must have respect for its explosive ...

  • Case study - Amine tail gas treatment

    COVERING YOUR TAIL GAS The discovery of new shale formations throughout the world and the development of new drilling technologies have increased natural gas production and prompted government agencies to instigate tighter air-pollutioncontrol regulations on processing operations.
