  • A study on Cu and Ag doped ZnO nanoparticles for the photocatalytic degradation of brilliant green dye: synthesis and characterization

    Novel polyvinyl pyrrolidone capped pure, Ag (1–3%) and Cu doped (1–3%) zinc oxide (ZnO) nanoparticles (NPs) were successfully synthesized via the co-precipitation method. The synthesized NPs were characterized by UV-visible spectrophotometry, X-ray diffraction (XRD), energy dispersive spectroscopy (EDS) and field emission scanning electron microscopy (FE-SEM). Compared to pure ZnO, the ...

  • Incineration Industry: Scrubber on Sludge Incinerator Reduces Atmospheric Emissions Case Study

    Aberdeen Sewage Treatment Plant in Aberdeen, Washington started up their new Electric Infrared Incinerator in May, 1981. The sewage sludge incinerator, product of Shirco, Inc., needed a pollution control device in order to meet state, local and federal requirements for atmospheric emissions, according to the emissions test on the unit performed January, 1982. Chosen was a Model 24×24- ...

  • Modelling emissions of perfluorinated chemicals to the Danube River Basin

    The emissions of two perfluoroalkyl acids (PFAAs) into the Danube River Basin have been estimated in a test of four different hypotheses regarding the factors affecting those emissions. The results were used to simulate water concentrations for comparison with measured data. The researchers found that incorporating wastewater treatment information and wealth distribution alongside population data ...

  • Mobile Stationary Source Emissions Testing, Coming to a Facility Near You?

    Last week, Antea Group had the unique opportunity to perform a RATA (relative accuracy test audit) of the emissions from a thermal oxidizer at an ethanol production facility located in Minnesota using a state-of-the-art mobile testing laboratory. During this RATA audit, actual stack emissions levels (including NOx, SOx, CO2, CO, O2, flow rate, temperature, velocity and pressure) from the ...

  • Case study - Engine test cell exhaust: RTO

    Overview A Mid-western outboard engine manufacturer bought a three year-old plant for the production of its marine engines. When finished, the engines are removed from the assembly line and run for quality control. The 25,000 SCFM of exhaust from testing contains volatile organic compounds (VOCs) that require regulatory compliance. Also within this exhaust is a great deal ...

  • Briefing paper: accelerating action to Save Peat for Less Heat!

    Emissions from drained and degrading peatlands (organic soils) amount to almost double the amount of CO2 emissions from aviation1, even when skyrocketing emissions from peat fires are not included. This briefing paper shows where the most urgent action is needed and presents a roadmap and policy recommendations for accelerating action. Peatlands cover only 3% of the global land surface. Some 15% ...

  • Content Analysis of Toxic Elements in Soil by Simultaneous ICP

    Contaminated soil not only leads to contamination of untreated drinking water through permeation into river water and rainwater, it adversely affects health when the soil itself is directly ingested as a child puts the ground into a stoma into a play etc. Therefore, assessment of soil toxicity using a defined method is required. I In Japan, the Soil ...

  • Are self-driving vehicles good for the environment?

    Autonomous transportation has lots of advantages. Reducing greenhouse gas emissions could be one of them. Can autonomous cars be a boon for the environment? The transportation sector is the second largest source of greenhouse gas emissions in the United States, accounting for 27 ...

  • Effect of carbon sources on nitrous oxide emission in a modified Ludzak Ettinger process

    Effect of methanol and glycerol on nitrous oxide (N2O) emission in two laboratory-scale modified Ludzak Ettinger (MLE) processes was investigated during three distinct periods: dissolved oxygen (DO) control by intermittent aeration with a DO controller, and high and low aeration rates. N2O consumption rate in an anoxic tank and aeration mode influenced N2O emission rates from ...

  • Hydro Nano Gas could be the Answer for Neutralizing Carbon Fuel Emissions

    Hydro Infra Technologies (HIT), a Swedish clean tech company based in Stockholm, has developed an innovative patent pending approach for neutralizing carbon fuel emissions by generating a novel gas called Hydro Nano Gas (HNG). In spite of all the advancement happening in the energy sector, globa economies are ...

  • Performance and emission characteristics of CI engine, fuelled with diesel and oxygenated fuel blends

    Vegetable oils are a potential alternative towards partial or total substitution of diesel fuels. In this study, we used ethanol as the solvent, and a bio fuel enhancer as additive to explore the possible use of higher percentages of biodiesel in an unmodified diesel engine. Biodiesel was produced from cashew nut shell liquid (CNSL) by pyrolysis process. A mixture containing 80% (by volume) of ...

  • AMETEK PI wins stack gas/emissions analyzer category bronze medal award in control magazine reader choice awards

    Every single interaction between customer and supplier is an oppor-tunity for providing good solutions. After awhile, these positive mo-ments really begin to add up. Despite the huge effort and extreme consistency required, the best vendors almost re¬ exively deliver useful products and services, and con-tinually develop and release new improvements and innovations. Con-sequently, over ...

  • Case study - Using thermal storage systems to reduce carbon emissions

    Aquifer Thermal Energy Storage (ATES) systems have the potential to provide a significant tool for climate change mitigation. Using aquifers as a source for thermal energy can provide heating and cooling for houses, offices and other buildings E-USE (aq). In comparison to the use of fossil fuels, as well as providing up to 60% CO2 reductions, these systems are also more cost effective. The ...

  • Another source of methane release

    Mary Kang wasn’t even originally looking at methane emissions. The Princeton doctoral candidate was trying to get to the bottom of another issue: carbon dioxide escaping after being stored underground. During that research, she got to wondering about methane emissions from old oil and natural gas wells. What Kang, now a Stanford postdoctoral researcher, and other researchers found could be ...
