Process Integration of CO2 Methanation for Synthetic Natural Gas Production

Abstract

In line with the vision of sustainable energy solutions and driven by a commitment to decarbonizing Shell’s energy products, the company is actively exploring the production of Synthetic Natural Gas (SNG) using eco-friendly methodologies. This initiative aligns with global ambitions to mitigate carbon footprints and resonate with the evolving EU regulatory environment.The study stresses two pivotal research areas:Renewable SNG Production: Focused on innovating low-carbon technologies, this segment delves into producing SNG through the integration of renewable CO₂ and green H₂ sources. The exploratory phase spans the complete production chain, right from harnessing renewable CO₂ from biomass-driven sources to the methanation process.SNG Liquefaction Challenges: A deeper probe into integrating the methanation process with SNG liquefaction, this segment emphasizes understanding the intricacies of introducing non-traditional components, notably H₂ and CO, into the liquefaction process. By employing sophisticated simulation tools, we've studied the potential implications on equipment and process efficiencies when integrating these new components.This study, enriched with a broad economic review, identifies optimal methodologies keeping in view economic feasibility, efficiency, and operational considerations. Through these research endeavors, Shell supports its commitment to pioneering sustainable energy solutions and provides a roadmap for future initiatives in the realm of SNG production
