  • Case study - Keeping ethanol production green

    OVERVIEW Originally published in Pollution Engineering Magazine. In an effort to reduce the world’s dependence on fossil fuels, there has been a major push towards alternatives. Ethanol has been at the forefront of this movement because it reduces greenhouse gas emissions from automobiles and its production has a positive net energy balance. The homegrown fuel also ...

  • Case study - Oxidizer energy recovery options

    Overview The mainstream media today is full of allusions to energy awareness and conservation. Just as visible these days are media references to astronomical dollar figures that can boggle the mind. This article does not seek to break out of that mold, but rather to conform to it – as Oxidizer Stack Heat Recovery offers a tremendous opportunity for both energy conservation and ...

  • Biodegradation of MTBE Utilizing A Magnesium Peroxide Compound: A Case Study.

    ABSTRACT: A patented magnesium peroxide compound was recently employed at an underground storage tank facility to increase the available oxygen in the groundwater for the biodegradation of fuel hydrocarbons. The objective of this remedial effort was to substantially reduce the dissolved-phase concentrations of BTEX and MTBE and to arrest further migration of the dissolved fuel hydrocarbon plume. ...
