Definitions
- Halogenated solvents can be used to dissolve/dilute the contaminants from the synthetic resin material. Again, usable synthetic resin material will be obtained by this process if the solvents do not extract essential components from the synthetic resin material. The halogenated solvent solutions will require distillation to recover the contaminants and recycle the solvents. In general, it is difficult to fully reclaim usable contaminants (such as oil) from the distillate. Furthermore, many halogenated solvents are ozone depleting compounds and potential health hazards to humans, and therefore their use and release into the environment are under regulation and close scrutiny by federal and state governments. d. Combustible or flammable solvents may be used to dissolve and/or displace the contaminants from the synthetic resin material.
- FIG. 1 a process for removing contaminants from post-consumer containers made from synthetic resin material in accordance with a preferred embodiment of the invention is illustrated.
- the present invention is particularly useful in the removal of oil from
- the solvent used in solvent cleaning system 10 is relatively soluble in liquid or supercritical carbon dioxide (more so than the contaminants being removed from the synthetic resin material in system 10). Therefore, one advantage of the present system is that carbon dioxide system 34 can operate at lower pressures than if carbon dioxide system 34 were directly solvating the contaminants. Operation at lower pressures tremendously lowers equipment costs and energy costs associated with liquefying the carbon dioxide.
- the solvent comprises an organic solvent other than carbon dioxide having a specific gravity (preferably at 20 0 C) of at-least about 0.76, more- preferably- between- about Or ⁇ -t. ⁇ , and most preferably between about 0.95-1.25.
- the operating conditions fo the distillation system depend largely upon the flash point of the solvent, but preferred solvents according to the present invention are typically heated to about 300 0 F and then re-condensed. The contaminant waste is then properly disposed or recycled. Recovery of the contaminant waste for proper disposal is an important advantage of the present invention. If the contaminants were not recovered , particularly the more toxic contaminants, they would likely wind up in a landfill along with the synthetic resin material where they could cause soil and groundwater contamination.
