Autocausticizing Questionnaire - Page 2

 Main Menu

   
 
Please either use the units provided in dropdown boxes or type specific units used at your mill in the right-hand boxes.
A. Pulp production:
B. Objectives:
 

1.

 What is the primary reason for your interest in Partial Borate Autocausticizing?
   

Reduce fresh lime consumption

   

Increase white liquor production

   

Off-load lime kiln (energy and/or maintenance savings)

   

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:

C. Key Parameters: (This information will be used to calculate the amount of borate required for your mill)

E. Recovery Boilers:
F. General Comments:
   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).
 Here you may also include any additional explanations and comments regarding questions in sections C to E.
