•Two types of heat-integrated processes, SWP and SCWP, are presented.•From economic aspects, it is verified that SWP is superior to SCWP.•From aspects of energy utilization, it is verified that SCWP is superior to SWP.•From aspects of CO2 capture, it is verified that SCWP is superior to SWP.
The design of hydrogen production, purification, compression and carbon dioxide capture is developed as two types of heat-integrated processes. The SWP (SMR + WGS + PCC) is mainly composed of the steam methane reforming (SMR) reactor, the low temperature water–gas-shift (WGS) reactor and the process of hydrogen purification, compression and carbon dioxide capture (PCC), and the SCWP (SMR + CO2R + WGS + PCC) primarily consists of the SMR reactor, the carbon dioxide reforming of methane (CO2R) reactor, the WGS reactor and the PCC. From economic aspects, it is expectable that the SWP process is superior to the SCWP process due to lower energy demand and less equipment. From aspects of energy utilization and CO2 capture, it is verified that the SCWP process is superior to the SWP process.
