资源简介：
The invention relates to a prehydrolysis-kraft process where the hydrolysate is withdrawn in a position where withdrawal capacity may be obtained over a longer operational period. According to the inventive process is the first volume of hydrolysate withdrawn from the process made after a moderate alkalization at end of hydrolysis (PR) and within a time period less than 10 minutes. Mechanical agitation and mixing effects in transfersystem (TR) prevents pitch deposits and clogging in top separator screen (31).
