  • Thermal Treatment Technologies

    Hot gas decontamination: Hot gas decontamination is a technology still in the pilot-scale of development that can be used for decontamination of explosives-contaminated masonry or metallic structures. The method involves sealing and insulating the structures, heating with hot gas stream to 260 °C (500 °F) for a prescribed period of time, volatilizing the explosive contaminants, and destroying ...

  • Common Treatment Technologies for Inorganics in Soil, Sediment, and Sludge

    The most commonly used treatment technologies for inorganics in soil, sediment, and sludge include solidification/stabilization (S/S), excavation and off-site disposal, and acid extraction. These treatment technologies are described briefly below. Solidification processes produce monolithic blocks of waste with high structural integrity. The contaminants do not necessarily interact chemically ...

  • Common Treatment Technologies for Radionuclides in Soil, Sediment, and Sludge

    Unlike organic contaminants (and similar to metals), radionuclides cannot be destroyed or degraded; therefore, remediation technologies applicable to radionuclides involve separation, concentration/volume reduction, and/or immobilization. The most commonly used treatment technology for radionuclides in soil, sediment, and sludge is solidification/stabilization (S/S). This treatment technology is ...

  • Wet electrostatic precipitators: A preferred technology for emission control

    The basic science behind electrostatic precipitators is as familiar and as simple as static cling. But today, this elemental force has been harnessed to a technology that is helping to remove millions of tons of toxic chemicals from our atmosphere; saving billions of dollars annually in pollution-related physical damage; and averting costly impacts on health and mortality rates for millions of ...

  • MECONTROL UBC Systems for Power Station Moorburg - Case Study

    Efficient City Power Plant Hamburg/ Germany, One of the largest new coal fired power projects is the new power station Moorburg with a net capacity of 1640 MW and with a heating capacity of up to 650 MW. The close vicinity to the city Hamburg makes it possible to increase the efficiency of the units by up to 46.5% with electricity only and 61% with heating. With SH and RH temperatures of ...

  • Ex Situ Thermal Treatment for Soil, Sediment, and Sludge

    The main advantage of ex situ treatments is that they generally require shorter time periods, and there is more certainty about the uniformity of treatment because of the ability to screen, homogenize, and continuously mix the soils. Ex situ processes, however, require excavation of soils leading to increased costs and engineering for equipment, possible permitting, and materials handling worker ...

  • Mining landfills and using the methane & garbage for Energy

    The revolutionary process of turning all waste into energy using RCBC Global Inc. technology will change the way we handle waste for the rest of time. RCBC has the power to mine existing landfills and use the garbage and methane for energy. We have a unique, tried and true system. It has had 30 months worth of tesing on 61 different fuels. These test results have proven to have a much lesser ...

  • Numerical simulation and field test study of desulfurization wastewater evaporation treatment through flue gas

    Aimed at cost saving and pollution reduction, a novel desulfurization wastewater evaporation treatment system (DWETS) for handling wet flue gas desulfurization (WFGD) wastewater of a coal-fired power plant was studied. The system's advantages include simple process, and less investment and space. The feasibility of this system has been proven and the appropriate position and number of ...

  • Solidification / Immobilisation of hazardous waste for subterranean storage

    The use of subterranean salt mines for the final storage of inorganic hazardous waste is state of the art in Germany, and in fact most other European countries. However, the technical requirements to prepare the waste in an appropriate way are quite challenging. Over ten years ago econ supplied a plant to a salt mine in eastern Germany. The plant uses econ’s unique batch-wise working mixing ...

  • Lightweight concrete mix profitable using heavyweight batch mixer

    To increase production of concrete mixes containing coal fired power generation plant ash products, Charah Inc. opened a new manufacturing plant in Emporia, VA, which also serves as a warehouse and distribution center for other concrete industry products. Profit margins are slim in this high volume business, so management placed great emphasis on the capital and operational costs of the equipment ...

  • H2S Oxidation and Sulfur Recovery

    Lubrizol’s facility in LeHarve, France produces a lube oil additive via a batch reaction that uses elemental sulfur as a reactant and produces H2S as a byproduct. Lubrizol selected Gas Technology Products LO-CAT® II Hydrogen Sulfide Oxidation Process to sweeten H2S emissions and recover sulfur. The LO-CAT II system was chosen for its ability to handle the process variation in H2S ...

  • Smart Series-Odor Management

    Tackling odors at composting facilities is a manageable task made simpler by inventorying and treating all sources and tapping into technology advances. Perhaps one of the most difficult realities that had to be faced 15 to 20 years ago by the composting universe is that the phrase, “odor-free” - at least when it comes to composting - is probably an oxymoron. Feedstocks that biodegrade within the ...

  • MSW Thermovalorization

    The problem of waste elimination has been a topical subject in the last decade due to the growing use of throwaway products and packaging, that make up 40% of the entire waste by now. In Italy more than 25 million tons of municipal solid waste  are produced every year. On average, every inhabitants in our country produce about 450 kg of waste per year, more than one kilogram per day.  Until the ...
