The properties of the selected petcoke and biomass, as well as
the composition of natural gas used for the steam reforming section,
are listed in Table 1. All different cases are simulated and
scaled in Aspen V8.6 based on the same combined energy of
feedstocks (petcoke with biomass and natural gas) as 1400 MW
(HHV) input. However, the choice of biomass with petcoke to
natural gas is a decision variable within the simulation, which depends
on market requirements and selected optimization scenario.
As illustrated in Fig. 1, the proposed polygeneration plant consists
of 10 major units:
