Abstract
This study proposed and evaluated the new hydrogen production design of the Gas Turbine – Steam Methane Reforming (GT-SMR) hybrid process. The superheated byproduct gas from the GT system is utilized as a combustion agent for the boiler of the SMR system, minimizing the required heat energy input for hydrogen production. The overall energy consumption and energy generation are calculated and simulated to determine the system’s operational performance. Under no efficiency losses, the design is tested to understand how the significant input parameters such as temperature, pressure, and steam/methane ratio (S/C) affect the system’s overall performance. From the data generated, the system’s efficiency was directly proportional to the pressure and temperature while inversely proportional to the S/C values. However, in actual applications, the menthane conversion rate often fluctuated depending on the adjustments of these factors, regardless of their thermodynamic relationship with the SMR efficiency. With the addition of other energy waste information, a complete simulation showed the reversed effect of pressure. Although the temperature and S/C ratio improved the overall performance, the hybrid system efficiency reached its limits beyond certain values.
