This research focuses on the utilization of Flare Gas Recovery units (FGRUs) to capture and repurpose gases like methane and LPG, which are typically flared during industrial processes. Despite their similarity to natural gas and superior energy potential, flaring poses environmental risks and economic losses. The study aims to design a specialized unit to reclaim flared gases, preventing hydrocarbon emissions while ensuring safety. It seeks to optimize recovery processes to maximize the extraction of valuable products like sales gas and LPG for energy use. The research examines the operational aspects of Flare Gas Recovery Systems (FGRS), employing liquid ring compressors for gas processing and separation. Economic and environmental analyses underscore the benefits of adopting FGRUs, particularly in the context of Egypt, where routine flaring contributes significantly to greenhouse gas emissions. By advocating for effective measurement and recovery strategies, the study aims to advance sustainable industrial practices, minimizing environmental impact while maximizing resource utilization and economic gains.
