Syngas compressor intercooler(s) is/are used to cool the
compressed syngas to 430 K, and heat is recovered to preheat
a portion of the condensate water for the steam cycle.
The gasification/combustion approaches including gas
cleanup are based on the SilvaGas process [16] as well as
input from an engineering consulting firm (AMEC E&C Services,
Minneapolis, MN) who collaborated with us on this
project, and provided input on technologies that could be used
for these applications. They also provided cost estimates
associated with BIGCC technologies. An economic analysis
related to the application of BIGCC technologies at corn drygrind
ethanol plants is presented in Ref. [20].
