This study evaluates condensate's performance as an alternate source of fuel. Also, the work explores how important system factors, such as pressure and temperature in the distillation column, affect the system efficiency under different operating conditions. Here condensate from the Kailashtila gas field has been collected and laboratory tests and simulation approaches have been performed to estimate different properties. First, the boiling point temperature is determined using ASTM D86 technique. Based on the results, we created the TBP curve; divided into its pseudo-cuts, and then estimated the physical and thermodynamic properties using DWSIM software. After that, the condensate is fed into an atmospheric and shortcut distillation unit, and the composition of the feed, distillate, and bottom products are generated, together with the pressure and temperature profile. The essential characteristics and column specifications are proposed, and the results are analyzed to observe the properties and energy consumption changes. Finally, the reliability of the study has been assessed by contrasting the outcomes from the simulation results with real field scenarios. According to the study, a distillation column with 12 trays and a height of 7 meters can produce products with specific gravities between 0.711 and 0.869 for this condensate sample. The study concludes that since medium-weight condensate can be distilled to create petroleum products like gasoline and diesel, it can be utilized as a fuel source. Changing the number of trays, column height, and feed temperature is recommended to influence the system’s performance and the quality of the user-end product.
