Simulation and Economic Evaluation of Flare Gas Recovery Using Nano Adsorbents

The oil and gas industry is facing a critical challenge with the growing emissions of flare gases, driven by the global expansion of the industry and increased fossil fuel consumption in refineries and petrochemical plants. the significant environmental impact of these flare gas emissions has created a pressing need to develop effective strategies to minimize the associated environmental risks. however, implementing technologies to reduce flare gas emissions presents both economic and environmental hurdles. in this study, we investigated the application of nanoadsorbents in packed bed towers as a promising approach to recover and repurpose flare gases. using matlab software, we conducted two case studies to evaluate the performance of different adsorbent materials, including ws and h silica gels, as well as a 4 å molecular sieve, for the recovery and conversion of sour flare gas into sweet, moist gas. the analysis revealed that the langmuir isotherm model provided the most suitable simulation results, demonstrating the technical feasibility and effectiveness of this approach.
