Synthetic phenol solutions were used to model a phenol-containing wastewater. A matrix of conditions of carbon dioxide pressure and temperature and phenol-water concentration was investigated. The testing program consisted of four parts, viz., (1) determination of distribution coefficients of phenol in a static system; (2) determination of selectivity (and verification of distribution coefficients) in a flow system; (3) determination of mass transfer effects; and (4) measurement of neat phenol solubility and separation of phenol at intermediate pressure. A description of the tests and the procedures for obtaining the data that can be used to assess the potential of extracting phenol-containing wastewater using supercritical carbon dioxide is presented.
