Conceptual design of syngas production systems with almost net-zero carbon dioxide emissions

This work describes three different configurations of syngas production processes using a combination of SMR (steam methane reforming) and DRM (dry reforming of methane). The ideal SMR + DRM process ensures the maximum product yield, the heat-integrated SMR + DRM process fulfills the maximum heat recovery, and the stand-alone SMR + DRM process effectively suppress net CO2 (carbon dioxide) emissions. Through specific optimization algorithms, the syngas production systems subject to almost net-zero CO2 emissions are successfully verified by simulations in Aspen Plus environment.
