Question 64
CHNAT2 marksNeeds review
Consider the flowsheet in the figure for manufacturing
via the reaction
in an isothermal CSTR. The split in the separator is perfect so that the recycle stream is free of
and the product stream is pure
. Let
denote the mole fraction of species
(
) in the CSTR, which is operated in excess
with
. The reaction is first-order in
with the reaction rate
, where
kmol/(m
h).
The reactor volume
in m
is to be optimized to minimize the cost objective
, where
is the recycle rate in kmol/h. For a product rate
kmol/h, the optimum value of
is ____ m
(rounded off to the nearest integer).GIVEN:
