The objective of this study was to describe the hydrogen production from catalytic reforming of liquefied petroleum gas (LPG) with carbon capture and storage (CCS). Nowadays, hydrogen requires a lot of attention as a clean fuel as well as a chemical used in industrial applications (e.g. hydrogenation processes especially in oil refinery sector). The size of evaluated plant was 100000 Nm³/h hydrogen with a purity of 99.95% (vol.) to be in line with industrial hydrogen production capacities used in the oil refinery sector. A pre-combustion CO₂ capture process based on Methyl-DiEthanol-Amine (MDEA) was also considered to reduce the greenhouse gas emissions (decarbonisation of fossil LPG used). The carbon capture rate was about 78%. The evaluation was made using process flow modeling (ChemCAD) and the simulation results were compared with experimental data reported in the literature. A similar hydrogen production process from LPG reforming without carbon capture was also considered to assess the energy penalty for CO₂ capture. This work is an important study for evaluation of reducing carbon footprint in oil refinery sector.
