  • Slug of Hydrocarbon contaminating amine case study

    A Gulf Coast refinery’s amine system was contaminated with up to 3% hydrocarbon. The contamination consisted of hydrocarbon from upstream process units and particulate. The hydrocarbon consisted of LCO and heavy diesel. The current system consisted of an undersized flash tank and a 20% slipstream filtration. The current system could not remove the contaminants so the refinery had to ...

  • Fast bioremediation of a hydrocarbon contaminated site

    The use of bioremediation has been demonstrated to be a very effective treatment technology for a hydrocarbon contaminated site within a month of starting. In addition to selection and preparation of an appropriate microbial inoculum the other key considerations were effective mixing, addition of suitable nutrients and maintenance of soil moisture levels. Careful management of all these ...

  • Evaluation of Microbial Communities Colonizing Stone Ballasts at Diesel Depots

    In this study, we evaluated the heterotrophic microbial communities colonising stone ballasts at diesel depots. The number of bacteria (both total culturable heterotrophic bacteria and hydrocarbon-degrading bacteria) was proportional to the level of hydrocarbon contamination. However, there was no significant difference in the level of total culturable heterotrophs (TCHs) and the hydrocarbon ...

  • The Extraction of Glycols From Water Using ENVI-Carb™ Plus Solid Phase Extraction Cartridges

    The analysis of glycols such as propylene and ethylene glycol from water samples is traditionally done by direct aqueous injection into a gas chromatograph. Aqueous injections are problematic in GC analysis due to issues such as the large expansion volume of water in the inlet, increased carryover, and elevated detection limits. In this work, we have evaluated a unique carbon adsorbent, ENVI-Carb ...

  • ORC® Replaces Pump and Treat/SVE Systems and Gains Site Closure

    Site Summary Leaking gasoline pipelines caused the groundwater to become contaminated with TPHg at concentrations exceeding 6,000 ug/L. Because the site was located in a busy, high traffic area (in the vicinity of Portland International Airport), the consultants made it a priority to find a less obtrusive and “invisible” remediation system to replace the pump and treat and SVE systems ...

  • Mineral oil bio-degradation within a permeable pavement: long term observations

    ABSTRACTThe paper reports on the first 300 days of a research project conducted at Coventry University, which has focused on the ability of a permeable pavement, reservoir structure to retain and treat petroleum-derived pollutants through in situ microbial bio-degradation. The research has required the construction of a full-scale model permeable pavement in the laboratory, which has been ...

  • Biotechnology of hydrocarbon bioremediation in soil washing slurry

    Application of Bioremediation for low cost contaminated soil washing slurry treatment with quick hydrocarbon reduction and improved sustainability. The application uses proprietary microbial formulation with a slurry bioreactor in order to accelerate the degradation process and to make it compatible with soil washing technology. The end result is a treated soil which meets the requirements for ...

  • HDPE - A Hydrocarbon Resistant Membrane?

    Most brownfield redevelopment and environmental protection applications require the use of a hydrocarbon resistant membrane.  However, each membrane material will vary in its ability to resist chemical attack and its effectiveness as a barrier to permeation.  It is essential that a barrier material prevents the migration of contaminants, thereby not harming the surrounding environment ...

  • Hydrocarbon contamination of a typical mangrove floor in Niger Delta, Nigeria

    The impact of petroleum hydrocarbons on the floor of a mangrove system located on one of the intertidal lands behind the barrier islands of Niger Delta basin of southern Nigeria was evaluated following the Obiafu-14 oil spillage. The area covered by the oil spill was delimited by reconnaissance and soils were sampled by grid method from the bottom and middle slopes of oil-affected and unaffected ...

  • Enhanced Bio-Remediation of Wastewater

    Bioremediation has been used to treat hydrocarbon contamination in municipal wastewater for centuries. Most microbes used in bioremediation today are naturally occurringyetspecifically chosen and cultured versus being genetically modified. Bioremediation rivals techniques such as pump and treat extraction systems, as it provide cost savings for municipalities, as well as environmental savings by ...

  • HRC® Reduces Chlorinated Hydrocarbon Contamination in a Complicated Geological Setting

    CASE SUMMARY Textile Facility, Northern France A subsurface plume of mixed chlorinated solvents developed as the result of historical operations at a textiles facility in Northern France. The plume was approximately 1,000 square meters in size. The complicated geology consisted of a gravelly silt (highly contaminated) overlying a silty sand (medium contamination) ...

  • Proof That Bacteria Degrade Oil

    There has been a lot of publicity and ‘noise’ around the ability of bacteria to degrade oil, especially following BP’s Gulf of Mexico incident.  However little has been shown to prove that biological remediation is an effective means of treating oil contamination. Over many years CBIO have worked to develop a range of a microbial products that have proven to be able to ...
