  • Description: One improved pulping process is modified continuous cooking (MCC). In MCC, the total alkali charge has been distributed through the various stages of cooking to maintain a more even alkali profile. The improved selectivity achieved by the MCC process allows mills to lower the kappa number to 22 or below for softwoods and lower than 15 for hardwoods. To address the problem that the high temperature of the cooking process has been identified as a major factor in contributing to significant yield losses, further modifications have been incorporated into the MCC process to lower the cooling temperature and prolong the cooking time while still achieving the desired "H factor."
