WARREN H. CHESNER Chesner Engineering, P.C. This paper presents an overview of a recently pat ented technology which defines the process of using selected waste products to assist in reclaiming existing municipal solid waste landfill sites [1]. The process in volves the pressurized injection of these materials into the void spaces of existing landfill sites to both manage the waste product an...
More than 100 million tonnes of municipal solid waste are incinerated worldwide every year. However, little is known about the fate of nanomaterials during incineration, even though the presence of engineered nanoparticles in waste is expected to grow. Here, we show that cerium oxide nanoparticles introduced into a full-scale waste incineration plant bind loosely to solid residues from the comb...
As pressure for new infrastructure and development grows, it is inevitable that building projects will encounter some of the c20,000 closed former solid waste landfills in the UK, many of which will have accepted municipal solid wastes (MSW). Construction on or across these sites brings a special set of geohazards associated with the potential for large and difficult to predict settlements, gas...
Besides the second generations bio fuels, one of the most promising products is the bio gas oil, which is a high iso-paraffin containing fuel, which could be produced by the catalytic hydrogenation of different triglycerides. To broaden the feedstock of the bio gas oil the catalytic hydrogenation of waste lard over sulphided NiMo/Al(2)O(3) catalyst, and as the second step, the isomerization of ...
Approximately 1.5 billion tyres are produced each year which will eventually enter the waste stream representing a major potential waste and environmental problem. However, there is growing interest in pyrolysis as a technology to treat tyres to produce valuable oil, char and gas products. The most common reactors used are fixed-bed (batch), screw kiln, rotary kiln, vacuum and fluidised-bed. Th...
On behalf of the International Solid Waste and Public Cleansing Association (lSWA), it is a pleasure to open this First Annual North American Waste-to-Energy Conference. Solid waste management has moved to the forefront of the environmental agenda. The level of activity and concern by citizens and governments worldwide has reached unprecedented levels. Nations are considering restrictions on pa...
A quartz-enhanced photoacoustic absorption spectroscopy (QEPAS)-based gas sensor was developed for methane (CH₄) and nitrous-oxide (N₂O) detection. The QEPAS-based sensor was installed in a mobile laboratory operated by Aerodyne Research, Inc. to perform atmospheric CH₄ and N₂O detection around two urban waste-disposal sites located in the northeastern part of the Greater Houston area, during D...
It is presented an optical fiber sensing system projected to operate in the demanding conditions associated with coal waste piles in combustion. Distributed temperature measurement and spot gas sensing are requirements for such a system. A field prototype has been installed and is continuously gathering data, which will input a geological model of the coal waste piles in combustion aiming to un...
during natural gas processing, water in natural gas may cause to hydrates formation in pipelines which may lead to serious damages to process equipments. given the problems raised by present of water in natural gas, glycol solvent uses to remove water.in contact of glycol with gas always an amount of btex and voc absorb along with water, which on glycol recovery process, these substances separa...
