dc.description.abstract | Solid biomass is usually simulated by decomposing it into a solid phase (carbon, ash, and
sulfur) and a gas phase (water and diatomic molecules of H2, N2, O2, and Cl2) from the proximate
and ultimate analysis before entering a reactor operating under chemical equilibrium when using
Aspen Plus. However, this method prevents the use of energy integration for the feed stream from the
system inlet to the reactor. This paper proposes an approach to solving this issue, considering biomass
with both known and unknown chemical compositions; the latter involves the decomposition of
biomass into complex molecular compounds. Different process arrangements were assessed to
achieve a realistic simulation, and a sensitivity analysis was carried out to examine the effect of the
concentration and heating upstream of the reactor, focused on supercritical water gasification (SCWG)
of orange peel. This process is very energy-intensive, so the approach is useful for a better calculation
of the energy requirement and exergy losses in a plant; these are usually and mainly related to the
train of heat exchangers. In addition to this application to SCWG, this approach can be used for
any other thermochemical process, such as gasification, pyrolysis, or combustion, and for any real
biomass. Upon a base case study using a wet biomass of 10,000 kg/h with 90 wt.% water where
the SCWG reaction takes place at 240 bar and 800º C, if the temperature at the SCWG reactor inlet
increases from 350º C to 400º C, the heat exchange increases by 57% from 4 MW and by 34% if the
water content decreases to 70 wt.%, although more heat relative to the solid is saved. | es |
