Dry ice is pure CO2, which is made by decompressing liquid CO2 to produce CO2 snow. The snow is then compacted and extruded through a die plate to form solid CO2 pellets. Dry ice is unstable above minus 78.6°C, but it will not melt into CO2 liquid, but directly sublimate into CO2 gas. It is this sublimation process that produces a cleaning effect when dry ice is used as a blasting medium. ...
For all contaminated surfaces tested, EPA PCB limit standards (Regulations 761.79, 761.123) of < 10 ug/100 cm2 were achieved upon decontamination with DeconGel 1102. ...
OBJECTIVE: Surface decontamination determination of DeconGel® formulations 1101 and 1102 on aluminum, carbon steel, and concrete surfaces contaminated with PCB (Aroclor 1016) oil following a modified version of Environmental Protection Agency (EPA) SW-846 Method 8082A, “Determination of PCBs by Gas Chromatography”. ...
ABSTRACT Facility decommissioning projects often include an environmental component that involves the identification of chemicals and hazardous building materials used at the site, decontamination or abatement of those materials, and proper disposal. PCBs are one chemical hazard that may need to be addressed during the dismantling of older industrial ...
