Description

Large quantities of heat, steam, and hydrogen are required in all major industrial sectors, including oil & gas and iron & steel. However, technologies for generating these products are large-scale emitters of CO2 and at the present time must still rely on fossil fuel feedstocks. More traditional methods, such as amine scrubbing, can be implemented to reduce emissions, but fall short of attaining carbon-neutral products. Pressurized chemical looping – steam methane reforming (PCL-SMR) has the potential to produce zero-emission H2 for combustion systems at an attractive cost, thereby avoiding the need for post-combustion CO2 capture. By operating at elevated pressures (7 bar(g)), zero direct CO2 emissions are achievable without the need for costly gaseous O2 production, while increasing H2 production efficiency and lowering fresh-water consumption. This work considers a comparison between conventional SMR with post-combustion CO2 capture and autothermal reforming (ATR) to that of PCL-SMR meeting the heating demands of a typical steam-assisted gravity drainage (SAGD) facility will full heat and water integration. In all configurations, syngas is cooled, the H2 product is purified via pressure swing adsorption before compression, and the tail gas is recycled into the combustor system. The captured CO2 is processed through cooling, drying, and compression units to meet transportation specifications. The presentation extends the previously reported performance results providing a full comparative techno-economic analysis (TEA) and life-cycle analysis (LCA). Potential key benefits of PCL-SMR beyond costs and environmental burdens will be discussed, such as reduced footprint and reformer tube stress.
