  • Combining HVME and Enhanced Bioremdiation for Gasoline Contamination in Groundwater.

    ABSTRACT A leaking underground storage tank at a commercial petroleum retail site located in Haskell, Texas resulted in soil and groundwater petroleum hydrocarbon contamination. This contamination, including benzene, toluene, ethylbenzene, and total xylenes (BTEX) and total petroleum hydrocarbons (TPH) migrated down-gradient below a road and neighboring property. Access below the adjacent roadway ...

  • Fuel Quality Monitoring System in Indonesia: case study on gasoline quality improvement

    This paper advocates periodical monitoring of fuel quality for conformation to quality standards. The Fuel Quality Monitoring System (FQMS) aims to phase out off-specification fuel from the market by a government initiative. The FQMS in developing countries has rather weak management because the insufficient analytical facilities and unskilled human resources result in inadequate monitoring by ...

  • The environmental aspects of the evaporation of BTEX from gasoline with and without ethanol

    In this work the vapours from two columns simulating gasoline–contaminated soils (with and without ethanol) were monitored. Standards mixtures of BTEX, containing different ethanol contents were also analysed. The instrumental analysis was performed by Gas Chromatography with a Flame Ionisation Detector. Among BTEX, except benzene, in both columns the evaporation rate increases with time. In the ...

  • High Resolution Detailed Hydrocarbon Analyses by Capillary Column Gas Chromatography

    In the petrochemical industry, samples such as petroleum naphthas and gasolines routinely must be quantitatively separated into their individual components.  Because these petroleum-derived samples consist of hundreds of compounds, petroleum analysts require chromatography columns that offer high resolution.  We have developed polar and nonpolar capillary gas chromatography columns to ...

  • Prediction of energy consumption of passenger transportation and GHG emissions in Jordan

    In this paper, the structure of the Jordanian transport sector is analysed with focus on passenger cars, which represent 65% of total vehicles and responsible for almost all of the national gasoline fuel demand. In order to achieve the objectives of this study, an empirical model is developed based on multivariate linear regression analysis to identify key drivers that influence gasoline ...

  • Simplified biofuels measurements with portable mid infrared analyzers

    Product quality begins at the production facility and extends to consumer filling station. Some process control or quality verification analyses can be done with quick and simple verification tests while others require more complete tests according to the ASTM or EN approved methods. Many crucial measurements can be performed by mid-infrared (IR) analysis. These measurements include free fatty ...

  • Monitor BTEX Compounds and Fuels in Water, Using Solid Phase Microextraction and Capillary GC

    BTEX compounds, kerosene, diesel fuel, or gasoline in water or aqueous suspensions of soil can be monitored by solid phase microextraction (SPME) and capillary GC on a short, narrow bore column (15mx 0.20mm ID).   A sample can be extracted and analyzed in less than 40 minutes.   Because no solvent is required, sensitive detection id scharacteristic of SPME/GC analyses.   ...

  • Methanol blending is alternative fuel of the future

    The main objective of “alcohol fuel power” field is increase of fuel resources for transport by using right alternative  such as ethanol and methanol blending with gasoline, which unlike pure oil fuel, are characterized renewable and have unlimited sources of raw materials. Margin of oil (valuable hydrocarbonic raw materials for petrochemical productions) and also a power ...

  • Towards sustainable household energy use in the Netherlands

    Households consume direct energy, using natural gas, heating oil, gasoline and electricity, and consume indirect energy, the energy related to the production of goods and the delivery of services for the households. Past trends and present-day household energy use (direct and indirect) are analysed and described. A comparison of these findings with objectives concerning ecological sustainability ...

  • The empirical analysis for fractal features and long-run memory mechanism in petroleum pricing systems

    The fractal behaviour for petroleum pricing is investigated in several international systems. Based on the time series of Brent & WTI crude oil and Rotterdam & Singapore Leaded gasoline prices (daily spot), this paper analyses the fractal features in the systems under study by using Rescaled Range analysis (R/S analysis). This paper also estimates the Hurst exponents; thus, long-term memory ...

  • Mitigation of road transport carbon emissions in Argentina

    This study describes a model to calculate energy consumption and CO2 emissions into the atmosphere by the road transport sector in Argentina from 1960 to 2050. The model analyses different mitigation scenarios to determine effective options to produce a sensitive decrease in carbon emissions. The results of this study show that by reducing the use of private vehicles while ...

  • Life cycle assessment of environmental and economic benefits of bio?ethanol in Taiwan

    To evaluate the benefits of Taiwan's bio?ethanol crop cultivation promotion on the environment, energy efficiency and economy, we undertake a recording of cultivation resources inputs data in 2007 and 2008 of four energy crops based on the LCA method. We find the net energy balance signifies energy conversion efficiency. As to the GHG, using sugarcane ethanol to replace gasoline could decrease ...

  • Household energy consumption in Switzerland

    Households consume more energy embodied in goods and services than they consume with energy carriers. Thus, energy assessments need to address both direct consumption and indirect consumption via commodities. This paper first presents a conceptual framework for describing and analysing the direct and indirect energy use of households. The framework is based on material flux analysis and ...

  • Biodiesel Analysis with Mid Infrared - From Feedstock to Fuel

    Introduction The biofuels industry is growing rapidly and so is the need for analysis to ensure quality product. The parameters for quality biodiesel require different types of instruments and measurement systems, such as gas chromatographs (GC), titrators, centrifuges, infrared spectrometers... Although claims are out there for the analyzer that will do it all, unfortunately there is no one ...

  • Quantitative Determination of Volatile Organic Compounds in Drinking Water by EPA Method with Headspace Trap GC-MS

    Volatile Organic Compounds (VOCs) refer to a group of easily vapourised organic compounds. Under atmospheric pressure, these compounds boil below 250C. Studies have shown that prolonged exposure to the VOCs could increase the risk of various health problems, such as cancer. VOCs are commonly present in gasoline, dry cleaning solvents and degreasing agents. Due to improper storage, disposal or ...

  • Needed: A copernican shift

    In 1543, Polish astronomer Nicolaus Copernicus published “On the Revolutions of the Celestial Spheres,” in which he challenged the view that the sun revolved around the earth, arguing instead that the earth revolved around the sun. With his new model of the solar system, he began a wide-ranging debate among scientists, theologians, and others. His alternative to the earlier Ptolemaic model, which ...
