Simulation and Optimization Blue Hydrogen Production by Steam Reforming Natural Gas

One of the most significant industrial processes for producing hydrogen is steam methane reforming. It is now essential to integrate carbon capture technology in order to convert to blue hydrogen due to the growing environmental challenges. This study integrates a CO₂ collection unit as a component splitter and PSA hydrogen purification as a component splitter separator to simulate the production of blue hydrogen using Unisim software R390.1. The simulation was run with a steam-to-carbon ratio of 3:1, a reformer outlet temperature of 830°C, and a pressure of 14 bar and water gas shift high temperature 300°C and low temperature 200 °C. The goal of this study is to optimize the process to produce more hydrogen while lowering emissions.
