Resumen:
This paper reports the simulation and techno-economic analysis of a
hydrothermal liquefaction (HTL) solar plant for bio-oil production from
forestry residues. The HTL solar plant is designed to process 1 ton of
biomass daily. The heat required by the HTL process is provided by a
parabolic trough solar collector field and a natural gas boiler to allow
continuous operation. The annual simulation of the thermal performance
of the plant is carried out using the TRNSYS software. The considered
location is Temixco, Me ` xico, and a Typical Meteorological year is
used to characterize the site's climate. The bio-oil yield is calculated
by a kinetic model that considers the biomass's composition and the
slurry's temperature. An economic model is implemented that includes the
costs involved and helps determine the bio-oils minimum selling price
for the system's financial viability. The obtained yields of biogas,
bio-oil, biochar, and organic aqueous phase are 13.3, 29.4, 13.6, and
42.9 wt%, respectively. The minimum fuel sale price (MFSP) for the
annual production obtained is estimated between $1.27 and USD 1.55/kg.
Eliminating transportation costs, the value of MFSP was assessed in a
range of $0.89 to USD 1.09/kg. The results show that integrating
concentrated solar thermal technology for processing lignocellulosic
waste from the sawmill industry may be an attractive, viable, and
sustainable option for producing biofuels, with potential application in
countries with high availability of forest biomass, such as Mexico.
