your interest in Partial Borate Autocausticizing? |
| |
|
|
Reduce fresh lime
consumption |

|
|
De-bottleneck recausticizing or other parts of the recovery cycle.
|
| |
|
|
Increase pulping yield |
| |
2. |
If you are looking to use borate
autocausticizing technology to enable an expansion (i.e. increase
pulp or white liquor production), please provide the following
information: |
| |
3. |
Provide any additional relevant comments. If an
expansion is planned, please indicate if you expect any other part
of
the liquor cycle to become the production bottleneck after
increased production. If so, please specify which part and explain:

Please explain specific operational problems that the mill may currently have
at any part of the liquor cycle
(e.g., evaporator scaling, recovery boiler
fouling or corrosion, green liquor scaling, lime kiln ringing, etc).
