  • Is `Dark Fuel` the same as `Bad Fuel` and can I still use it?

    Algae-X FAQ’sIs 'Dark Fuel' the same as 'Bad Fuel' and can I still use it?This is a question many of us have asked more than once. And what we really want to know is: 'Will the stuff damage my engines?' Engines are expensive, ruining an engine is costly and operating an engine on 'bad fuel' is not wise. We all know that most engine failures start in the fuel tank. When all mechanical parts ...

  • Transformations of n-alkanes from petroleum pollutants in alluvial groundwaters

    Abstract Investigations presented in this paper were aimed at defining the alterations of n-alkane composition in cases of oil-polluted alluvial sediments. Therefore, oil-polluted groundwater samples, taken in five different time intervals during a period of 28 months, were investigated. Samples of alluvial sediments were taken from two boreholes within an oil refinery at Pancevo, Yugoslavia. In ...

  • How Does Fuel Stability Affect Me?

    Fuel stability is a serious concern for the diesel fuel user. The chemistry of diesel fuel instability involves the chemical conversion of precursors to species of higher molecular weight with limited solubility. The conversion process often involves oxidation of the precursors. Fuel solvency plays a role, since the development of insolubles is always a function of both the presence of higher ...

  • A look at some contaminants regulated in drinking water

    The U.S. Environmental Protection Agency regulates just over 90 contaminants in public drinking water systems. They include manmade chemicals as well as naturally occurring contaminants from rocks and soil. A look at some of the contaminants that fall under federal or state regulations: ARSENIC: Enters drinking water through eroding natural deposits in the ground or mining and other ...

  • Denmark’s Near-Zero-Waste Wonder

    Has this Danish community found the formula for environmentally friendly industry? When we look closely at systems in nature — coral reefs or rainforests, for instance — we see something we don’t often see in human systems: mutually beneficial relationships and energy flows among the various elements, such as air, water, rocks, soil, and plant and animal life. If we ...

  • Engineered wetland removes subsurface hydrocarbons while providing beneficial reuse

    British Petroleum (BP) is operating an engineered wetland to treat petroleum-contaminated groundwater at a 300-acre site in Casper, WY. Release of petroleum products during refinery operations from 1908 until 1991 resulted in significant petroleum hydrocarbon contamination. Over 44,000 yd3 of LNAPL were removed by dual-phase recovery wells and oil/water separators constructed in 1981, but ...

  • ATCO Midstream & grow-gen energy to develop Canada`s first integrated bioRefinery

    ATCO Midstream and Grow-Gen Energy announced today that they have signed an initial partnership agreement to develop Canada's first Integrated BioRefineryTM. The refinery will use organic wastes and high-starch wheat to create green electricity, biofertilizer and fuel ethanol. "ATCO is proud to be a partner in this world leading technology," said Nancy Southern, President and CEO of the ATCO ...

  • How did palm oil become such a problem — and what can we do about it?

    Production of this ubiquitous ingredient is devastating for the environment. Solutions are complex, but they are out there. Last August, from the window of a jet high over Sumatra, I counted nearly a dozen plumes of smoke rising from the vast jungles and plantations below. Some more than a half-mile wide, they looked like pillars holding up the sky. That week the ...

  • The Potential of Solar-Powered Water Circulators to Help Solve Serious Water and Energy Problems in the U.S.

    With increasing human populations comes the corresponding increased need for improving water quality in lakes, wastewater ponds, potable water reservoirs, and other water storage facilities. Providing circulation within water reservoirs of all types has long been known to provide meaningful benefits, but the costs to achieve sufficient circulation through diffused aeration or mechanical mixers ...

  • Treated vs. Untreated Cooling Tower Water: Risks for Your Plant

    When an industrial plant or building decides whether or not to invest in a cooling tower water treatment system, it is a decision that shouldn’t be taken lightly. Petrochemical plants, chemical manufacturers, refineries, and all kinds of large buildings and facilities using cooling towers, whether they’re used as part of the industrial process or for cooling/removing heat from the ...

  • Controlling Scale Deposition and Industrial Fouling

    It costs US industry billions of dollars a year to control and remove the limescale that builds up in industrial equipment such a heat exchangers, evaporative coolers, boilers, chillers and other water fed equipment. Oil wells, for example, face significant scaling problems from the highly mineralized water that are extracted with the oil. Limescale not only increases downtime, maintenance ...

  • Water Quality Models

    ' In order to determine the impacts of a particular discharge on ambient water quality, it is usually necessary to model the diffusion and dispersion of the discharge in the relevant water body. The approach applies both to new discharges and to upgrading of existing sources. This note provides guidance on models that may be applicable in the context of typical Bank projects.' Introduction ...
