Appeal No. 95-2535
Application 07/987,127
having a higher efficiency yield than said first urea
synthesis reactor;
b) distributing an overall production capacity that
exceeds that of said pre-existing plant to apportion from 60
to 95% of said overall capacity to said first urea synthesis
reactor and from 5 to 40% of said capacity to said second urea
synthesis reactor.
The manipulative step recited in a) of claim 9 is
"providing . . . a second urea synthesis reactor", which is
consistent with the preamble indication that the claim is
drawn to a method of "revamping an existing urea production
plant." This part of the claim includes a construction step
that results in a modified urea plant.
The manipulative step recited in b) of claim 9 is
"distri-buting an overall production capacity" between the
"first urea synthesis reactor", i.e., the pre-existing
reactor, and the "second urea synthesis reactor", i.e., the
reactor added in step a) of claim 9. The step of
"distributing capacity" presumes that reactants are being
distributed between and transported to the two reactors.
Thus, step b) presumes that urea is being synthesized and the
plant is operating. Step b) appears to be inconsistent with
the preamble. If the plant is operating, then a method of
