The increasing global energy demand and the urgent need to reduce CO? emissions have positioned Carbon Capture, Utilization, and Storage (CCUS) as a pivotal strategy in mitigating climate change. This study focuses on designing an integrated model for surface facilities and supercritical CO? transportation using a pipeline-compression system in the CCUS program for Field A, located in the Northwest Java basin. The objectives include designing surface facilities for CO? injection, determining optimal pipeline operating conditions, and selecting appropriate materials for pipeline construction. The methodology involves a comprehensive literature review, data collection, and simulation using Aspen HYSYS and PIPESIM software. The study utilizes data on stream input, gas composition, and pipeline specifications to simulate the CO? injection process. Field A, with a reservoir depth of 3740 ft, is identified as suitable for CO? injection, potentially increasing production by 37.9%. Results indicate that CO? undergoes two compression stages to achieve a high-pressure, low-temperature state before being transported. The pipeline design employs API 5L X65 grade pipes, ensuring supercritical CO? conditions are maintained throughout transportation. The study concludes that maintaining CO? in a supercritical phase is crucial for optimizing pipeline material and size, with critical conditions identified at 87.74°F and 1070 psia. This study provides a framework for implementing efficient CCUS systems, highlighting the importance of integrated surface facility design and optimal pipeline operation to achieve emission reduction targets.
