抄録

Removal tests of toxic organic compounds from aqueous solution have been carried out using the continuous solvent Sublation method. Naphthalene (NAP) and penthachlorophenol (PCP) are chosen as a model compound to be removed, and n-octanol is used as a organic phase for their recovery. In order to simulate the effect ofphysical and chemical properties of the organic compounds on the removal, the removal model for continuous solvent sublation is constructed on the basis of batch solvent sublation model. The concept of the removal model for continuous operation is mainly constructed by two terms, that is, the removal by bubbles such as adsorption on the bubble, entrainment with boundary layer of bubble, vaporizationinto bubble, and the mass transfer to the organic phase placed at the upper part of the sublation column.The optimum operating conditions for the continuous solvent sublation such as the gas and aqueous flow rateand the organic phase volume are discussed for evaluation of its practical utilization.http://ci.nii.ac.jp/naid/10002470927
