(see Figure 1) includes a compressor 17, a combustion chamber 3,
a mixing chamber 1, a steam generator 18, a gas turbine 19, a
feed water pre-heater 20, a condenser 21, an air decomposition
device 24 for producing O2, and a liquefier 23. Similarly, the
Goto plant (see Figure 1) includes a compressor 1, a combustion
chamber 3, a gas turbine 2, a boiler 5, a condenser 8, an O2
manufacturing apparatus and compressor 11 and 12, and a
liquefier-separator 14. Of particular interest are Gruel’s
liquefier 23 and Goto’s liquefier-separator 14.
Greul teaches that the liquefier 23 functions to separate,
fluidize (i.e., liquify) and discharge excess CO2 gas extracted
from the main CO2 cycle (see pages 3, 7 and 11 in the
translation).
Likewise, Goto teaches that the liquefier-separator 14 acts
in conjunction with an extraction line 13 to separate, liquify
and discharge excess CO2 gas extracted from the main CO2 cycle,
explaining that the amount of CO2 gas extracted corresponds to
the amount of O2 fed into the system upstream of the combustion
chamber 3 (see pages 2 and 7 through 12 in the translation).
In determining that the subject matter recited in claims 1
and 29 is anticipated by Greul and that the subject matter
recited in claim 1 is additionally anticipated by Goto, the
