Syngas Generation By CFD Simulation of Kinetic Model and Heat Transfer in Steam Methane Reformer

This research illustrates the computational fluid dynamics (CFD) simulation to show the effect of inlet Steam/Natural gas flow rate and inlet temperature on efficiency of steam methane reformer (SMR). In syngas production, the approach to get higher ration of H₂/CO is (SMR) which requires a high endothermic reaction and heat source. This work carried out on the reactor design of (SMR) to achieve optimal dimensions for the highest rate of reaction. H₂O/NG, feed temperature, syngas selectivity, and catalyst productivity are the parametric studies in this study. In addition, the length and diameter of chamber are determined as a variable to investigate the temperature distribution through the r and z directions in reactor. To prove the accuracy of developed model, the simulation results are compared with the available plant data at steady state condition. The pilot plant tests were conducted in a reactor chamber at temperatures of 1073–1273 K, steam of 0-3 Ib/h, and 3-5 kg Ni catalyst bed. In this study the dropping temperature was observed between 250-300 K.
