Remedial Spill Clean-Up Technology

A patented product technology was developed for abatement of spilled hydrocarbon and chemical waste. Efficiency improvements were made to the product formulations allowing new applications to be demonstrated such as "Decontamination, Destruction and Abatement of Chemical and Biological Agents for an Air Force Depot Environment." The chemical and biological agents were detoxified and the residuum was subsequently remediated providing a significantly lower level of toxicity. These excellent results include 100% Bacillus atrophaeus (ATCC 9372) anthrax simulant kill on a 107 population. This efficacy level was verified at the Air Force Research Laboratory in San Antonio, TX on the live Stern strain of B. anthracis. The project also investigated various needs on Air Force Bases such as drum cleaning, automotive depot cleaning and small spill cleanup. One of the biggest benefits of the technology is its ability to remediate hydrocarbon contaminates down to 10 – 50 ppm whereas some of the competitive technologies often leave behind up to 2 – 3 orders of magnitude more contamination behind. The patented product was commercialized for various types of spill clean-up on hard surfaces and soil remediation. This product was developed with the financial support of the Department of Defense (DoD), Oklahoma Center for the Advancement of Science and Technology (OCAST) and the Environmental Protection Agency (EPA) SBIR programs.

"Safe" Acid Spill Neutralization Technology

Most people are unaware how unsafe age old technologies are for neutralizing concentrated acids.  We developed a novel and useful product for safely neutralizing and remediating the acid under a DoD contract.  The product includes a colored indicator to tell when the neutral pH range is reached. Other benefits are:

    1. When neutralized, the acid turns the product into a fairly dry solid that is easy to reclaim for disposal as opposed to liquid carbonates and bicarbonates that are still liquids after neutralization creating a mess to clean up.
    2. Other dry powdered neutralization products such as carbonates or bicarbonates may under neutralize an acid leaving an environmental hazard. Acids tend to absorb into the dry powder form a matrix into which the acid is absorbed, and therefore it cannot be fully neutralized. This is essentially a corrosive solid or thick “playdough-like” substance until it is hydrated with water and neutralization is completed. Then we have situation 1 above.
    3. Carbonates and bicarbonates produce carbon dioxide when acid neutralization is performed. Although carbon dioxide gas is not particularly toxic, asphyxiation is a concern when the gas is allowed to accumulate in poorly ventilated spaces (STEL 30,000 ppm CO2).
    4. Less heat is generated during neutralization with this product than with carbonates or strong bases making it a safer product.
    5. Certain acids contain hazardous heavy metals such as chromic acid. The heavy metal will be encapsulated or bound in the form of a heavy metal insoluble silicate that can be easily recovered for proper and safe disposal.

Although this product is a remarkable new acid neutralization product that can be used with a great many different acids, one shouldnotuse it for neutralizing hydrofluoric or hydrocyanic acids.

 

Solidifying Polymer Spill Clean Up Absorbent

This patented product is a unique abatement product for hydrocarbon and selected chemical spill clean-up applications on water or any solid surfaces. Once the hydrocarbon is absorbed into the polymer powder, the hydrocarbon tends to plasticize the polymer into a polymeric mat, abating the hydrocarbon in the three dimensional polymer. The product delivers excellent remediation resulting in low TPH (typically less than 10 ppm) in the affected water depending on conditions. This product is environmentally safe and superior to other existing technologies since it:

    • Will not absorb water
    • Floats indefinitely before and after abatement until it is recovered
    • Effectively absorbs more than ten times its weight
    • Will not adhere to shorelines or other materials
    • Can be recycled or used as a bulk energy source
    • Works in Extreme Temp/Weather Ranges
    • Solidified material could be classified as non-hazardous reducing transportation and disposal costs
    • EPA NCP Listed
    • Canada ESTS Listed
    • California Fish & Game Department Approved

A Canadian distributor of this product has introduced the fastest, safest, most efficient, and easy method to spread (special device) and recover (special ship) the polymer solidifier after abatement of the oil from a spill on water.  The company only uses this product. This is an option now available since the occurrence of the BP Gulf oil spill.

 

Oil Field Brine Remediation Product

Salt contamination of soils is a serious environmental issue facing the oil and gas industry today according to many stripper well operators and state regulators. The first SWC Phase I project developed a solution that offers a rapid and economical way to remediate salt damaged soils and enhance oil field aesthetics for new and old brine contaminated sites. The Phase I project involved a laboratory testing effort to evaluate the proposed hypothesis followed by three mini-field tests to verify the results. The Phase II project was a commercialization effort to expand the number of field tests for further verification.

This project demonstrated this cutting edge technology isthe best solution to an age-old oilfield problem with the customer benefits of being Rapid, Simple, Economic, Dependable and Environmentally Safe. The most valuable benefit israpidity. Provided the soil receives 1 – 2 inches of rainfall after remediation, the soil chemistry occurs rapidly allowing vegetation growth within 2 – 6 weeks instead of years as in the  case of using gypsum. There is no other brine remediation product that can compete with this capacity at this time. Support for this conclusion is the field test success ratio was 91% in the worst season in 75 years for growing grass in terms of high temperatures and minimal rainfall. The brine amendment was simplified or made to be customer friendly during this field testing program. The amendment is available in two forms. It is a dry material that is soluble/dispersable in water as a spray for application by service entities. The product is also available in a dry blend and can be applied in dry form with a spreader without generating dusting issues. The amendment application rate has been correlated with sodium ion concentration to make it simple to understand how much amendment must be applied. The only requirement is a sodium ion test from a laboratory. The amendment is considered economical and it is effective (generally one treatment required) which means low material, labor and equipment costs. The application rate is approximately twice what is needed for the top six inches of soil in order to interact with sodium at a deeper level as it migrates with soil moisture content. The product is dependable because it was verified by multiple field tests. The amendment is Environmentally Safe because the components are either considered “food grade” by the FDA or have agricultural use applications.

Other amendment benefits are found in the source of calcium component which has 100 times the solubility in water when compared to gypsum.  This is probably the key to providing rapid remediation. Another component is a proprietary multi-basic component of the mixture.  This mixture and other components have the capacity to:

    • Chelate sodium, boron and heavy metals in a preferential manner,
    • Provide organic matter,
    • Assist in rejuvenation of the bacterial population,
    • Provide nutrient transport to plants
    • Absorb light hydrocarbons

One of the most important components is rainfall. Approximately 1 – 2 inches of rainfall is needed to initiate the remediation chemistry.  Nothing happens until sufficient rainfall occurs. Another important component is the fertilizer which is usually a 10-20-10 or 13-13-13. Native grass seed or Bermuda sprigs may be planted immediately after remediation.
