Nanovapor Demonstrates Rapid Suppression of Explosive Gases

Nanovapor Refineries, Inc performed a demonstration on July 11th at the site of the Ennis natural gas refinery in Fairfield, Texas of its technology for the safe degassing of confined spaces and the suppression of explosive gases known as Lower Explosive Limit (LEL) standards.When empty, oil and gas storage tanks are most volatile and pose the greatest risk for explosion.  The tanks pose the greatest risk to employee and public safety at the time they are discharged.  The oil and gas industry takes particular care, and spends considerable amounts of money, to periodically “degas” storage tanks when they are empty to make them safe for maintenance and repair work.  In the post 9/11 era, the industry must take special care to ensure that empty tanks are secure from terrorist attack.  Many refineries and storage facilities are located in urban areas or in proximity to ports and interstate highways, and risk of terrorist attack must be mitigated to protect the public and the Nation’s critical energy infrastructure.Degassing is the process by which volatile organic compounds are removed from the empty storage tank. The presence of the vaporized compounds within the empty tank makes it susceptible to explosion. The damage done by the explosion of just a relatively small empty oil tank in the Hemel Hempstead oil depot in the United Kingdom in 2005-- the largest explosion in Britain’s peacetime history--will run into the billions of dollars.  It is believed that a spark ignited a vapor leak.  Under conventional processes degassing takes hours or days, depending on the size of the tank, and may cost up to $25,000 each day to complete the process.  Nanovapor has developed a new process based on advanced technology that dramatically reduces the time for degassing which brings considerable improvement to the security of refinery operations.The “nano” in the Nanovapor name refers to the operation of special chemistries at the “sub-micron” level. (1 micron = 0.001 millimeters).    Conventional degassing processes are slow and expensive processes.  Under the Nanovapor process, special chemical neutralizing agents are vaporized into sub-micron particles within the delivery system.  These agents form the “nanovapor”: chemical neutralizers that are so small they can successfully treat the very difficult air contamination problems existing within the empty tanks, problems often measured in parts per billion increments. “Nano” is a descriptive term, highlighting a breakthrough that works precisely because of the very small chemistries involved.  The practical result is that the empty tanks can rapidly be made safe for maintenance and the window of vulnerability to terrorist attack is greatly reduced.At the Fairfield sight  a new, 500 barrel frac tank (a mobile storage tank) of approximately 21,000 gallons capacity was charged with sufficient petroleum product to create an LEL level of 7%+ and to cause the safety monitoring meters to sound a hazardous and explosive environmental alarm.Once the explosive levels were achieved, the Nanovapor Intrinsically Safe Air Drive Unit (NVISAD) was started at 1:20 PM and Nanovapor LEL chemistries were introduced to the test vessel. Within 6 minutes of run time (1:26PM), Nanovapor LEL suppressed the explosive gas levels to “0%” of LEL, creating a non-explosive atmosphere. Immediately after creating a safe, non-explosive environment, the second NV chemistry, Petrozyme, was introduced through the same equipment to suppress the volatile toxic, aromatic hydrocarbon components to allow safe personnel entry and inspection. Safe conditions for personnel entry were achieved in another seven minutes of run time.  The Nanovapor process adds substantial value to refinery operations and capital asset utilization and contributes to the public safety, safety of refinery employees, and the protection of the Nation’s energy infrastructure.  It improves both the velocity of product moving through the refinery’s supply chain and the security of the international supply chain.  It enhances the security of the international port through which oil and gas products move by decreasing the time storage facilities are most vulnerable to explosions, either by accident or terrorist attack. The Nanovapor processes contribute to a clean environment, and are particularly important to refineries and port operations striving to operate in ways friendly to the environment.  When using the NV process, volatile organic compounds (VOCs) that may be harmful to the environment are suppressed.  The NV process sequesters and encapsulates the contaminants and makes them unavailable to the environment. The NV processes treats aromatic hydrocarbons through catalytic destructive adsorption to make them unavailable to the environmentFor further information contact Gary Wilkinson, CFO, at 978 683 2161 or 617 331 8499 (m), or email gary@nanovapor.com.  For complete information on our products and services, visit us at www.nanovapor.com
