Based on a gas turbine, LM1600PD, which has a capacity of
13.78 MW, manufactured by GE Energy Aero-derivative [36], three
EvGT systems, including a reference system without CO2 capture
and two systems combined with chemical absorption and oxyfuel
combustion respectively, were set up. The cycle performance was
studied by simulating those systems with the simulation tool, Aspen
Plus, which calculates the mass and energy balance. The simulation
results can further be used to calculate the electricity
generation and to identify the capacity of equipment. It shall be
noted that the economic analysis in this study is only based on
CO2 capture and CO2 compression, and the costs associated with
transport and storage are excluded according to IPCC special report
[1].
CAPCOST [37] is used to estimate the bare module costs (BMC).
Based on the results, the key economic parameters, like total
investment costs (TIC), operating & maintenance costs (O&M),
and cost of electricity (COE) are estimated. The cost of CO2 avoidance
(COA) is evaluated by referring to the reference system. By
doing breakdown analysis, the potential to reduce COA is further
investigated.
Moreover, the six-tenths-rule [37] is used to scale up/down to a
new capacity when investigating the impacts of plant size. If the
