  • Co-gasification of wood and polyethylene with the aim of CO and H2 production

    Abstract  This article describes the gasification of polyethylene–wood mixtures to form syngas (H2 and CO) with the aim of feedstock recycling via direct fermentation of syngas to ethanol. The aim was to determine the effects of four process parameters on process properties that give insight into the efficiency of gasification in general, and particularly into the optimum gasification conditions ...

  • Waste Rock Back Analysis

    On October 4, 2004, during field measurements collected in trench LFG-008, a crack developed in the middle of the trench. This occurred during the destruction of the Goat Hill North (GHN) rock pile at the Questa site. The crack varied in width up to a maximum of 100 mm and extended in an arc pattern around the pushed out section of the slope. The slope had been pushed in a convex arc out from the ...

  • Analysis of Isocyanates using the ASSET EZ4-NCO Dry Sampler

    Introduction Isocyanates are used as a raw material to produce a number of products such as automotive paints, rigid and spray foam insulation, and furniture. Personal exposure can occur while the products made with isocyanates are being applied, or when the materials are removed by grinding or thermal degradation. Workers who are exposed to these compounds are at risk for respiratory ...

  • Aerating recycled water on mushroom composting sites affects its chemical analysis and the characteristics of odor emissions

    Recycled water (RW) containing compost leachate can be a potent source of foul odor on mushroom composting sites. Samples of RW were repeatedly collected from storage tanks and pits of 14 mushroom composting sites in England and Ireland. Relationships between the effects of submerged aeration of the RW, the chemical and microbial characteristics of the RW, and the odors emitted were investigated. ...

  • Overview of Rotating Disc Electrode (RDE) Optical Emission Spectroscopy for In-Service Oil Analysis

    Introduction The basis of modern oil analysis is the use of optical emission spectroscopy (OES) to measure the ppm (parts per million) levels of wear metals, contaminants and additives in oil samples. Whatever else an oil lab may measure, a multi-elemental analysis is the core of in-service oil analysis. This paper gives an overview of Rotating Disc Electrode Elemental Spectroscopy and its ...
