Frequently Asked Questions (FAQ)

The phase-out of Class I ozone depleting compounds under the terms of the Montreal Protocol creates serious disposal concerns for organizations having chlorofluorocarbon (CFC) refrigerants and halons at their facilities. While much of the pure material can be reused, contamination with other compounds prevents significant quantities from being recycled or reused. As these materials cannot be buried on land, discharged into water or released to the atmosphere, destruction is the sole means of ultimate disposal. For this, Commodore offers Solvated Electron Technology (SET™). 

SET™ can destroy CFCs and Halons. SET™ is a patented, non-thermal chemical treatment technology developed by Commodore that destroys virtually all halogenated organic compounds. CFCs absorbed on solid materials can also be remediated using Commodore's commercial SET™ unit. 

SET™ uses solvated electron solutions to create free electrons. When liquids, soils or other materials are put in contact with the solution, the free electrons effectively strip off halogens to form salts, hydroxides, etc., destroying the hazardous compounds. Benzenes and phenols are converted to straight-chain hydrocarbons. The SET™ process destroys the CFCs and halons, without creating additional environmental issues.
One of Commodore's commercial SET™ units proven in the destruction of CFCs and Halons is shown in the photograph to the left. The equipment is mobile and able to be placed at a work site, eliminating the expense of transporting hazardous materials.
The end products from SET's destruction of CFCs are principally metal salts such as sodium chloride and sodium fluoride, sodium formate. These non-hazardous end products can be disposed of economically. 

ADVANTAGES OF SET™ FOR DESTROYING CFCS AND HALONS 

  • Recognized by the US Environmental Protection Agency (EPA) as a non-thermal process equivalent to incineration n its destruction capability, SET™ is the only multi-matrix chemical destruction process approved for nationwide operation.

  • CFCs and halons are destroyed, not just removed or concentrated.

  • Original liquids, soils and other materials can be reused or disposed.

  • As a closed system, produces no hazardous secondary wastes or off-gases.

  • Operates at ambient temperatures.

  • Transports and sets up quickly in less than 4000 sq. ft of space.

  • Can be scaled to accommodate the size of the project.

  • Requires minimal amounts of power, water and other outside support. 


REPRESENTATIVE EXPERIENCE 

Commodore has conducted numerous tests using SET™ for the destruction of CFCs and halons. In bench, pilot and commercial quantities, destruction has been complete with efficiency greater than 99.99%. The table below lists the various CFCs destroyed by SET™.
