PROCESS OF PURIFYING WOOD PULP WITH CAUSTIC-BORATE SOLUTION AND RECOVERING THE PURIFYING CHEMICAL |
摘要 |
<p>System and methods for purifying wood pulp by caustic-borate extraction. The systems and method include a method for recovering both the caustic and borate compounds from the resultant hemicaustic effluent, so that they may be recycled and re-used. Efficient recovery of these components is enabled by a nanofiltration system that has one or more alkali-resistant nanofiltration membranes.</p> |
