Heat integration technology is used to recover the wasted heat. Heat coupling of heat exchangers is optimized in SMR and PSA sections. Energy consumption is reduced to 39.5% that of the conventional process. ar ti c l e i nf o ab stra ct Article history: Hydrogen has been widely researched as a promising alternative fuel. Steam methane reforming (SMR) Received 25 February 2015 coupled with pressure swing adsorption (PSA) is one of the most dominant processes for hydrogen Received in revised form 11 May 2015 production. In order to reduce the energy consumption,
