Producers and end-users of hydrocarbon products like crude oils, refined oils, lubricants and tars constantly struggle to continue to stay effective, while also being effective environmental stewards of our society. As such, there are common problems associated with the production and use of hydrocarbon products; accidental releases and spills, stained equipment, and environmental threats to the soil, groundwater, aquatic life, and humans. To date, the contemporary industry’s solution to this problem has been to use even more hydrocarbon or emulsifiers to break down heavy hydrocarbon deposits from equipment, while “digging and hauling” the contaminated soil and materials from the spill/release site, then replacing the contaminated soil with “clean fill” soil.
While this methodology has been an effective means of eliminating the hydrocarbon from the area of interest, it has not been as effective an environmental management tool when considering the impacts of the area with additional truck weight and disturbances, the final disposition of the hydrocarbon-laden soil, or a relevant management tool for aquatic hydrocarbon threats, hydrocarbon-stained equipment, or hydrocarbon-stained concrete slabs and pours. Fortunately, the U.S. Environmental Protection Agency (USEPA) allows for onsite “in situ” remediation techniques and processes.
While many options for hydrocarbon containment/remediation techniques exist (including oil booms, chemical dispersants, mechanical recovery, applied sorption materials, and bioremediation), each has select limitations. As such, the USEPA has identified favorable hydrocarbon remediation techniques (HRT) and explains that “chemical oxidation typically involves reduction-oxidation reactions [or “redox reactions”] that chemically convert hazardous contaminants to nonhazardous or less toxic compounds that are more stable, less mobile, or inert” (USEPA, 2006, p. 9). Another option is a technique where the “mobility of organic and inorganic compounds can be reduced through various precipitation, complexation, and adsorption reactions. Commonly applied inorganic stabilization agents include soluble silicates...” (USEPA, 2006, p. 6).
The five commonly used techniques utilized in the process of remediating hydrocarbon contamination (microbes, hydrogen peroxide, persulfate, permanganate, and ozone as O3) also have limitations to their effective use in certain “in situ” applications. These include altering the soil pH, soil temperatures, microbe cannibalism, and additional aquatic life threats. HydroClean Pro Plus works differently to avoid these typical threats.
Rather than creating additional process problems and environmental threats, HydroClean Pro Plus uses a combined approach, utilizing a uniquely designed reactive silica-based formulation to initiate a high- energy redox reaction, allowing it to react to hydrocarbon and trap the hydrocarbon within the silica cell. This “micro-encapsulation” renders the hydrocarbon both insoluble and immobile. Consequently, HydroClean Pro has been demonstrated to be safe in aquatic/marine environments, as well as land-based applications. Measured total petroleum hydrocarbon (TPH) concentrations may be effectively reduced to at or under state guidelines when applied correctly.
