Process heat (PH) only, combined heat and power (CHP), or
biomass integrated gasification combined cycle (BIGCC)
systems are integrated to provide process heat only or both
process heat and electricity to the 0.19 hm3 y1 natural gas-
fired dry-grind corn ethanol plant. The technical analysis for
integrating the biomass systems into the dry-grind corn
ethanol process is described in detail in De Kam [19], De Kam
et al. [4,5], and Zheng et al. [10]. The technical analysis was
performed primarily using Aspen Plus process simulation
software. Some of the important features are summarized
