<p>PURPOSE:To separate and recover an org. component from an aqueous phase by supplying carrier gas preliminarily containing an amine type org. solvent into an alsorbing apparatus where activated carbon having the org. component adsorbed thereon is received to separate the org. component bonded to the activated carbon. CONSTITUTION:Carrier gas 20 which contains an org. component to be a gaseous mixture is taken out of an adsorbing apparatus 13 through an exhaust valve 17b and piping 30 and subsequently transferred to a condensing cooler 18 to be cooled and liquefied by the cooling water 40 passing through the condensing cooler 18. Thereafter, the liquid mixture containing the org. component is supplied to a continuous decanter 19 continuously provided with a plurality of tanks through pipeing 50 to be separated into an org. solvent phase and an aqueous phase on the basis of specific gravity difference. Further, both phases are respectively taken out as waste water 60 and a recovered solvent 70 by liquid feed pumps 21, 22. The recovered solvent 70 can be reused as it is without generating any trouble.</p> |
