Solubility of naphthalene in compressed ethylene was measured with a single-pass, continuous-flow apparatus at temperatures of 35, 50 and 65°C respectively and for a pressure range of 8 to 62 atm.
A calculation method is presented for determining the solubility of a heavy solute in a supercritical gas solvent. The modified BWR equation of Lee and Kesler together with a pseudocritical method was used to calculate fugacity coefficients of the solute in subcooled liquid and vapor phases. The utility of the method presented is illustrated by a calculation of the ethylene-naphthalene system at temperatures between 12 and 65°C and over a pressure range of 8 to 300 atm.
