Partial borate autocausticizing is used to supplement the
conventional lime causticizing. It is a sound alternative to kiln
investments or fresh lime solutions in kraft or soda pulping since
almost no capital investment is required. The borate compounds remain
in the liquor cycle self-regenerating to be used time and time again to
produce caustic.
Typical applications of partial borate autocausticizing
which have been tested in commercial trials are:
-
To reduce fresh lime usage and lime
mud disposal associated with lime kiln production constraints;
-
To accommodate a partial production
increase without investments in lime kiln and recausticizing
equipment;
-
To off-load lime kilns to increase
their energy efficiency; or
-
To off-load lime kilns to decrease
the operational costs associated with kiln downtimes.
Partial borate autocausticizing is not
for every pulp mill; a sound value fit is required to justify the
