Abstract Correlations for variation of water solubility with salt concentration are presented for hydrocarbons. The results for solubility in salt water are applicable to the complete range of salt concentrations, including water without salt ( X = 0) to water saturated with salt ( X = 358, 700 ppm(wt)). The correlation and experimental results are in favorable agreement. The results are provided in an easy to use tabulation which is especially applicable to rapid engineering usage with the personal computer or hand calculator.
