METHOD AND DEVICE FOR TREATMENT AND DISPOSAL OF SPENT ION-EXCHANGE RESIN

摘要

Method and device for treatment and disposal of spent powdered or bead ion-exchange resin. Said resin is suspended, fed into the plant where it is de-watered, dried, heat-treated and mixed with a binder and water. The resulting mixture is disposed into a container (19), where it is left to solidify into a body in which the resin is contained as a filler. Vapours given off from the resin during treatment are collected in ejector circuit (17). Said vapours that comprise at least water vapour and volatile organic compounds such as methanol and amines are condensed into a condensate. Said volatile organic compounds contained solved in the condensate are separated from the condensate, resulting in a condensate substantially free from said volatile organic compounds and a vapour containing said volatile organic compounds whereafter said volatile organic compounds are destructed, whereby they are substantially transformed into CO2, H2O and N2.
