  • Recovering coal bed methane from deep unmineable coal seams and carbon sequestration

    Published data from nearly 2,000 coal samples comprising 250 coal beds from 17 states, representing many of the coal producing horizons in the USA, shows moderate correlation (0.7) between depth and methane content for high volatile coal ranks. Low-volatile rank coals average the highest methane content, 12.74 m?/ton (450 ft?/ton), subbituminous rank coals the lowest, ...

  • Tortilla Manufacturer Wastewater Case Study

    TSS Drops from 1,883 ppm to 14 ppm This facility manufactures corn tortillas using a solution of Lye to peel the skin from the corn and soften the corn. The pH of the sample was received at 13.80 indicating a high basic solution. To minimize operating costs, CO2 was used to drop the pH down to 8.0 instead of using the traditional acid. The high pH water required ...

  • Carbon credit from composting of municipal solid waste

    The estimation of carbon credit from composting of MSW has been presented in this paper. The Municipal Solid Waste (MSW) used in formation of windrow was collected from the NERIST campus. Loss on Ignition (LOI) was measured which represents the amount of carbon and remaining ash in solid waste samples after ignition. As an absolute measure of biodegradable carbon, LOI provides an excellent ...

  • The CO2 and SO2 capture capability of two Greek limestones during repeated thermal cycles

    In the present study, two Greek limestones from the Megalopolis and Florina areas were used to capture CO2 and SO2. The regeneration ability and decay of the limestone samples were investigated through sorption-calcination cycles in a thermogravimetric analyser operated at ambient pressure. The effects of the sorption time (3, 8 and 30 min), reaction temperature (750°C and 850°C) and particle ...

  • Leaves of Lolium multiflorum as indicators of airborne trace element distribution in Central Italy

    Ambient air contains particles, ranging from sub-micrometric aerosols to clearly visible dust and sand grains. Plants during evolution developed the ability to maximise light interception and CO2 assimilation and also the efficiency to collect the airborne pollutants. Therefore, plant tissues have been used as indicators of trace elements air pollution. Lolium multiflorum leaves were used as a ...

  • Methane emissions reduction from organic wastewater and solid waste co-composting: parameter estimation and sensitivity analysis

    Using the approved large scale methodology AM0039 and approved baseline methodology AM0010, an estimated 7,329.04 tCO2e/yr are typically generated from degradation of organic wastes at the landfill in Mauritius. Baseline emissions for anaerobic degradation of organic wastewaters (OWW) in open lagoons approximated to 36,036 tCO2e/yr; 402,783.92 tCO2e/yr for transportation of OWW and municipal ...

  • Is there a cointegrating relationship between Australia's fossil-fuel based carbon dioxide emissions per capita and her GDP per capita?

    Carbon dioxide (CO2) emission per capita of Australia, a high-income economy with a fossil fuel-rich fuel-mix, is proven to have a strong cointegrating relationship with her gross domestic product (GDP) per capita. A conditional equilibrium correction model (ECM) has been developed to quantify the relationship between the two variables by employing the autoregressive distributed lag bound-testing ...

  • Why can’t I control the pH of my aquifer? - pH and Acidity are not the same

    Acidity is the amount of base required to neutralize acids present in a water sample. This is important because it determines the amount of buffer required to adjust aquifer pH. Since acids can disassociate to different extents, two solutions with the same pH can have different acidities. The figure to the right shows the pH of solutions containing 0.5 N HCl and 1.0 N acetic acid. The initial pH ...

  • Exploratory study of some potential environmental impacts of CO2 sequestration in unmineable coal seams

    An initial investigation into the potential environmental impacts of CO2 sequestration in unmineable coal seams has been conducted, focusing on changes in the produced water during enhanced coalbed methane (ECBM) production, using a CO2 injection process (CO2-ECBM). A high volatile bituminous coal, Pittsburgh No. 8, was reacted with synthetic produced water and gaseous carbon dioxide at 40C and ...

  • Degradation rate of sodium fluoroacetate in three New Zealand soils

    The degradation rate of sodium fluoroacetate (SFA) was assessed in a laboratory microcosm study incorporating three NZ soil types under different temperature (5, 10 or 20 °C) and soil moisture (35% or 60% water holding capacity) conditions using OECD Guideline 307. A combination of non‐labelled and radio‐labelled 14C‐SFA was added to soil microcosms, with sampling and analysis protocols for ...

  • Response of soil microbial activity to temperature, moisture, and litter leaching on a wetland transect during seasonal refilling

    In nutrient impoverished landscapes in southwest Australia, terrestrial litter appears to be important in phosphorus (P) turnover and in the gradual accumulation of P in wetland systems. Little is known about the fate of P leached from litter during the wet season and the associated effects of soil microclimate on microbial activity. The effects of temperature, moisture, and litter leaching on ...
