cost-effective method for CO
2
capture from a cement
plant even further should CO
2
be put to benecial
use, that is, MeOH. The recirculation of CO
2
as ballast
and absence of nitrogen signicantly reduces stack
freight, allowing for better gas clean up. With the
environmental concerns minimized, the operator’s
focus can be directed toward the efcient produc-
tion of high quality clinker. Oxygen combustion will
integrate the separate components of a cement plant
even further. This may pose operational challenges as
shutdowns or “upsets” in parts of a cement plant can
lead to a shutdown of the entire pla ...
