Abstract
A method for recovering halogenated hydrocarbons (FCH) from synthetic foams wherein halogenated hydrocarbons (FCH) are released from synthetic foam in a hermetically sealed processing chamber and transferred to a gaseous carrier medium of steam. The steam/FCH mixture is removed from the processing chamber and subjected to condensation to remove pure FCH from the condensed water.
Claims7
A method for recovering halogenated hydrocarbons from plastic foam, comprising subjecting plastic foam containing halogenated hydrocarbons to a steam carrier medium to transfer said halogenated hydrocarbons to said steam carrier medium, condensing said steam carrier medium and separating water from said halogenated hydrocarbons, and then compressing and condensing said halogenated hydrocarbons to liquefy said halogenated hydrocarbons.
