  • Research on mass transfer columns: passe?

    Since university research on mass transfer columns has decreased significantly in recent years, it is discussed whether the current knowledge of mass transfer technology for trays, packing materials, and column internals is sufficient to design energy- and cost-efficient systems. Points of view are described that have not yet been clarified from an industrial position and should play an important ...

  • Refractories, plastics, insulation or textiles containing chromium compounds - Case study

    Purpose The original version of this Plant Service Bulletin (PSB-43) was issued in April of 1990 to alert owners and operators of boilers and steam generators that certain materials containing chromium may, under certain operating conditions, produce hexavalent chromium (Cr + 6), a carcinogen. It also suggested remedial action and substitute materials. The initial issue of PSB-43 ...

  • Assessing the potential for restoration of surface permeability for permeable pavements through maintenance

    Permeable pavements (PPs) have been in use as stormwater management systems in Canada and the United States for over 20 years. After years of exposure to sediment and debris build-up, surface clogging reduces the infiltration of stormwater and inhibits the hydraulic and environmental functions of the pavement. Removal of surface material has been shown to restore infiltration but the majority of ...

  • Techniques for Assessing the Nonlinear Resilient Response of Unbound Granular-Layered Structures

    The resilient stress-deformation characteristics of aggregates that form granular pavement layers are reviewed. A standardized plate bearing test (PBT) is proposed that separates resilient and permanent deformation readings and detects material stress dependency. A nonlinear, stress-dependent model proposed by Ehrler is used to reproduce the observed deformation behavior of a granular layer ...

  • Art or Science?

    The choice between dilute phase pneumatic conveying and flexible screw conveying is not always clear Everyone has rules of thumb when it comes to choosing a conveying system — rules based on bulk material characteristics, required flow rates and distances, source and destination, plant configuration, and other variables. But those with experience in all types of systems will tell ...

  • Used Furnaces & Ovens

    Industrial ovens and furnaces are both heated chambers used to process raw materials at higher temperatures than what can be obtained in open-air systems. There is a range of heat treatments possible with both industrial furnaces and ovens, and the main purpose of any heat treatment is to change the mechanical of physical properties of a material. Some examples of materials that benefit from heat ...

  • Case study - Engine cell exhaust: Catalytic oxidizer

    Overview Endurance testing of outboard motors for boats has typically been done in lakes and sometimes on barges. This testing was time consuming, presented logistic problems and removed the testing from the R & D department and the factory. When a company in Oklahoma decided to build their own endurance test cell area, the Environmental Protection Agency required them to control the ...

  • Creep not a factor for Geocell load support

    An accurate understanding of creep resistance is essential to proper material selection when using polymers, and in the case of geocells, this science is being misapplied.  The definition of creep deformation is the tendency of a solid material to move slowly or deform permanently under the influence of mechanical stress.  Creep is something that creates fear and uncertainty with all ...

  • Beyond Laboratory Research on White Rust and Passivation

    EVAPCO initiated an in-depth study to investigate the formation and control of white rust. This study, which began over three years ago, led to the development of industry-leading research equipment specifically designed to evaluate white rust formation on evaporative heat transfer surfaces. A small-scale closed circuit cooler was designed and built to replicate the dynamic conditions ...

  • Biosolids composting at the Borough of Mechanicsburg, PA WWTP

    The Borough of Mechanicsburg, located in central Pennsylvania, was experiencing challenges in finding sufficient agricultural fields to continue the beneficial use of their anaerobically digested liquid wastewater treatment plant Class B biosolids. At the time, the only alternative available was dewatering and going to landfill, which is significantly more expensive. Due to environmental ...

  • Viscous heating effect on deactivation of helminth eggs in ventilated improved pit sludge

    Viscous heating by extrusion of faecal material obtained from ventilated improved pit (VIP) latrines can be used to deactivate soil-transmitted helminth (STH) eggs by increasing the temperature of faecal sludge uniformly. Viscous heating can deactivate STH eggs present in sludge to make the material safer to transport, dispose of, or use in agricultural applications or as an energy source. The ...

  • Clay Lumps under Simulated Hydraulic Transport Conditions

    Laboratory experiments with compacted kaolinite-bentonite mixtures indicate that degradation of hydraulically transported clay lumps in a dredge pipeline can be predicted and controlled to some extent. The size reduction of these lumps depends not only on the length of the pipeline but also on the density of the clay being dredged, the plasticity index (PI) of the clay, and the velocity of the ...

  • Installation of a grout curtain at a hazardous waste landfill

    Abstract: An existing inactive hazardous waste landfill located in Niagara Falls, New York was exhibiting migration of contaminants due to lateral groundwater flow in the underlying dolomitic limestone bedrock. It was determined that the installation of a vertical barrier to redirect the groundwater flow around the landfill would be the key element in the abatement design. Further review ...
