Fig. 15 illustrates the proposed process concept for trireforming
of natural gas using flue gas from fossil fuel-based
power plants, where HT represents heat transfer or heat
exchange including reactor heat up and waste heat utilization.
The tri-reforming process could be applied, in principle, to the
production of industrially useful syngas (for synthesis of
methanol and dimethyl ether, for Fischer–Tropsch synthesis,
and for high-temperature fuel cells) by reforming of natural gas
using gas mixtures (containing CO2, H2O, and O2) as co-feeds.
Such mixtures include, but not limited to, the flue gas from
either natural gas-based electric power plant or coal-based
electric power plants or the flue gas from partial oxidation units
in chemical manufacturing facilities.
