  • Coal-to-liquid fuels poised for a comeback

    Converting coal into liquid fuels is known to be more costly than current energy technologies, both in terms of production costs and the amount of greenhouse gases the process emits. Production of coal-to-liquid fuel, or CTL, has a large carbon footprint, releasing more than twice the lifecycle greenhouse gases of conventional petroleum fuels. However, with the rise in energy prices that began ...

  • How Do You Choose the Best Reverse Osmosis and Nanofiltration Membrane System for an Industrial Facility?

    As global demands for clean water increase, more and more industrial facilities are looking toward membrane filtration solutions, such as reverse osmosis (RO) and nanofiltration (NF), to help manage intake, process, and waste water treatment. Using membrane filtration can help your facility reuse wastewater and virtually eliminate discharge fees, and depending on the industry or required use, it ...

  • Tire Shredding: Alternatives to Landfills

    For many reasons, whole tires pose a major problem to landfills. The most obvious is the inefficient use of space. The actual rubber of a tire takes up only a small fraction of the space a tire occupies, and the rest of the space is wasted. A less obvious but far more serious problem is that tires may trap methane gasses when buried with other garbage in landfills. When this happens, the tires ...

  • Why is Energy-from-Waste slow to catch on in the U.S.?

    Nithin Coca reports in TriplePundit that Energy-from-Waste (EfW) is growing fast in Europe and parts of Asia. But it’s relatively stagnant here in the United States. In fact, the percentage of waste we burn for energy is actually slightly down in the past five years. What’s holding the U.S. back from this potentially sustainable solution? This stagnation is even more ...

  • Oil Recycling - Case Study

    The problem: Waste oil recycling contributes very much to climate protection through (CO2) energy saving. Compared to the production of base oil the re-refining of waste oil uses 34 % less resources. In the sixties the German government was subsidising the re-refining of waste oil. Because of that the use of waste oil as a fuel was neglected. The used oil re-refining is the ...

  • Scrubber Removes Grease and Particulates from Air Exhaust

    Operating Issue A food-industry leader in Alabama operates several pork-sausage cookers that exhaust over 4,000 ACFM of moisture and pork grease. The operator installed Electrostatic Precipitators (ESPs) to treat the exhaust but these systems performed poorly and generated high maintenance and operating costs. Additionally, these systems were antiquated and required significant capital ...

  • From a 1m3 cubitainer to 50mm chips, using a two-shaft shredder? With SatrindTec, “Sí, es posible!”

    A Spanish manufacturer of HPDE cubitainers and containers based in Cataluña has chosen SatrindTech to implement its recycling line of defective cubitainers. The request received by our Sales Department was to replace an existing SatrindTech twin-shaft shredder, in use since the mid-1990s, to now be able to ensure a regular size of the shredded material. ...

  • Reverse Osmosis and Nanofiltration Membrane Filtration Systems: Common Problems and How to Fix Them

    Reverse osmosis (RO) and nanofiltration (NF) are membrane filtration technologies that are designed to remove solute ions and molecules from a pretreated liquid stream. Well-designed RO/NF units are compact and demand relatively little maintenance, making them an attractive alternative to conventional treatment trains. Even despite the merits of today’s efficient RO/NF technologies, it pays ...

  • Biomass and Integration in Future Energy Systems and the Bioeconomy

    Biomass was the primary source of materials and energy until the industrial revolution set off a series of major changes around two hundred years ago. In the industrialized world fossil fuels became the primary source for energy in the forms of electricity and heat and provided almost all fuels for transport. However, biomass continued to maintain an important role in the economies in both ...

  • Kansas Facility Finds Fast, Reliable Fix to Cavitation Damage

    The Hutchinson (Kansas) Water Plant gets its water from 20 wells. The water is pumped out of the wells and into a reverse osmosis water treatment center to purify and ensure safe drinking water. At that point, a portion of the water is taken off from the main line, run through the reverse osmosis system and then mixed back ...

  • Underground Coal Gasification: Converting Unmineable Coal To Energy

    Currently, about 1.5 billion people –almost a quarter of the world’s population— are without electric power. The International Energy Agency estimates that world energy demand (for all forms of energy, including transportation fuels) will increase by 36 percent by 2035 and fossil fuels, such as coal, will continue to play a critical role in meeting this demand. What is ...

  • Coal sorption characteristics and coal surface tension

    Underground coal mining in the Bulli Seam of Sydney Basin, Australia encounters the problems of coal and gas outburst as the coal contains high concentration of CO 2 , where certain parts of the seam have been found to be especially hard-to-drain. In order to better understand these problems, the influence of temperature and moisture on sorption capacity of bituminous coal was investigated at ...

  • The restructuring of the international coal industry

    The international coal industry is now becoming a global industry emerging from a history of production for national purposes and isolated regional markets. The participants in the market are also changing; the oil companies have come and gone and production is now in the hands of specialist mining companies. This has implications for the way the industry is organised. Deregulation in the ...
