Hydrocarbon condensate recovered from natural gas may be shipped without further processing but is stabilized often for blending into the crude oil stream and thereby sold as crude oil. In the case of raw condensate, there are no particular specifications for the product other than the process requirements. The process of increasing the amount of intermediates (C3 to C5) and heavy (C+6) components in the condensate is called “condensate stabilization”. The purpose of this work aims to investigate Reid Vapor Pressures (RVP) values in a back-up condensate stabilization unit with a given feed of condensate and obtaining the best actual operating parameter for each of equipment. On the basis specified target for stabilized in this unit, two properties of product should stabilize before storing in storage tanks and export which for RVP of maximum 10 psia for summer season and 12 psia for winter season. Based on the research, it is found some techniques of condensate stabilization which are flash vaporization and fractionation. The separation of the feed is using flash vaporization in back-up unit which does not have any distillation column and just uses heating and flashing processes as we want to have simple process in case of plant shut down. In back-up CSU, salt and sulfur content are not affect the process as there are no any distillation in column and it operate only for shut-down plant as well as not a continuous process. Results show that CSU’s RVP and sulfur content is 7.932 psai and 2408.52 ppm which is the optimum condition for the process.
