Abstract

A METHOD FOR PULP PROCESSING USED IN CONNECTION WITH A PRE-HYDROLYSIS KRAFT PROCESS (PHKP) INCLUDES ADDING WOOD CHIPS OR SIMILAR MATERIAL TO A REACTION VESSEL, PERFORMING PRE-HYDROLYSIS, AND NEUTRALIZING THE MIXTURE WITH A FIRST QUANTITY OF WHITE LIQUOR FOLLOWED BY A DIFFERENT SOLUTION SUCH AS A COLD CAUSTIC EXTRACTION ALKALINE FILTRATE OPTIONALLY ENRICHED WITH WHITE LIQUOR.THE NEUTRALIZATION FLUIDS ARE REPLACED WITH A COOKING FLUID COMPRISING A HOT BLACK LIQUOR AND ALKALINE FILTRATE, OPTIONALLY ENRICHED WITH WHITE LIQUOR.THE COOKING FLUID MAY HAVE A RELATIVELY HIGH EFFECTIVE ALKALI CONCENTRATION. THE COOKED PULP MAY EXHIBIT VERY LOW RESIDUAL HEMICELLULOSES AND A KAPPA NUMBER WITHIN AN OPTIMAL RANGE.
