Accumulation of waxy deposits is a commonly occurring problem during transportation of oil in pipelines. Removal of these undesirable wax deposits by methods such as the addition of chemical inhibitors, and heat tracing of flow lines, requires a knowledge of the solubility of long-chain alkanes in liquids such as heptane. Solubilities of tetracosane, dotriacontane, hexatriacontane, and mixtures of hexatriacontane + dotria-contane in heptane were measured at temperatures ranging from 280 to 350 K at atmospheric pressure. Several equations were evaluated for their ability to predict the solubility in these systems. Comparisons between measurement and prediction are shown.
