Optimization Simulation of Condensate Stabilizer Unit on X Field Gas Well Case Study

- This study examines the stabilization process of condensate from reservoirs. The condensate needs stabilization before further processing to prevent loss of valuable components, safety risks, and environmental pollution. The stabilization aims to separate light hydrocarbon C1-C4 as well to increase medium and heavy C5+, and also to reduce the vapor pressure of the condensate, marked by Reid Vapor Pressure (RVP), which is climate- dependent. This research focuses on Field X in East Java, processing gas and condensate in a Floating Production Storage Offloading (FPSO) using distillation, fractionation, and flash vaporization within the Condensate Stabilizer Unit. The goal is to analyze the influence of temperature on fuel gas, RVP, and optimal condensate volume produced at Field X. Using Aspen HYSYS Ver.12.1 simulation modeling and Peng and Robinson fluid packages method, the study found that temperature significantly affects RVP, fuel gas, and condensate production, with optimal conditions at 173°C, RVP of 8. Psia, fuel gas usage of 0.0681 MMSCFD, and condensate production of 4222 bbl/d. The study provides operationalrecommendationsto optimize reboiler duty temperature, condensate volume, fuel gas, and RVP at FPSO X.
