Investigation of Physical Properties of Disulfide Oil and Condensate Mixture

The simultaneous utilization of Disulfide Oil (DSO) and Condensate is known as a novel mixture that has drawn researchers’ attention. The usage of such products is applicable when only precise experimental physico-chemical data are available. The DSO is produced as a waste and byproduct of gas sweetening process, which contains several disulfide components. Moreover, condensate is known as a valuable industrial product that is liquid at atmospheric temperature and pressure. Adding condensate to DSO makes it more economically feasible for export and may upgrade thermo-physical properties of DSO.Moreover, adding condensate to DSO promotes its potential applications. In this research work, different volume fractions of these two products from zero (0%) to 100% of DSO were tested by Refractometer, Tensiometer, Rheometer, Salinometer, and Calorimeter. It was found that the obtained refractive indexes linearly decreased from 1.5215 to 1.4277 by increasing the volume fraction of condensate at ambient temperature and pressure.Subsequently, the surface tension values decreased from 30.6 to 19.9 mN/m via quadratic function. The Rheometer results showed that various mixtures of these two products depicted a Newtonian fluid behavior in which their viscosity increased from 0.54 to 0.69 mPa.s by adding DSO at a standard temperature of 15.5˚C. The salt concentrations in condensate and DSO were achieved 26.096 and 30.265 g/m3 respectively. The calorific value of DSO was almost half of that of condensate value. It was observed that the condensate heat of combustion reduced by adding DSO.
