Simulation and Modeling of Steam Methane Reformation Uti-lizing Nickel-Based Catalyst

Our methodology started with an extensive review of the literature on Steam Methane Reformation (SMR) systems, establishing a foundation for anticipated outcomes while pinpointing gaps in essential fluid or geometric conditions. These gaps were then filled using standardized values from existing literature. We employed two methodologies for system modeling and optimization. Initially, Ansys Chemkin was utilized to solve SMR mathematical models utilizing the plug-flow reactor model, thereby determining optimal operational parameters such as temperature, pressure, and catalyst geometric dimensions (diameter and length). Subsequently, these optimized parameters were integrated into models of both single-catalyst pipes and multi-catalyst pipes, which underwent simulation using the Computational Fluid Dynamics (CFD) software ANSYS Fluent. Preliminary findings suggest that optimal operating conditions for SMR fall within the range of 800 – 1000°C and 25-28 bar, with expected fluid velocities reaching up to 20 m/s under these conditions. Corresponding dimensions for the catalyst tube within these parameter ranges were determined to be 49 mm in length and 176 mm in inner diameter. By validating the efficacy of SMR and identifying potential enhancements, the rationale for installing more SMR reactors in both new and existing facilities is justified. This strategic expansion facilitates the more efficient utilization of resources, thereby contributing to our capacity to meet the continuously escalating energy demands of the present and future.
