Apparatus for extracting plasticizer

摘要

An apparatus for extracting plasticizer from polymer structures includes, in one embodiment, a evacuation chamber, a heat source and a cooling chamber are all coupled to a conduit having a motorized fan for cycling gases through the components. The plasticizer is evaporated within the evacuation chamber by the heat source and entrained in a gaseous stream passing through the evacuation chamber. The plasticizer enriched gases are then passed through the cooling chamber wherein the plasticizer is condensed prior to being cycled back to the evacuation chamber. A gas heater aid in maintaining a constant gas flow temperature within the evacuation chamber.
