Abstract

With development of the theories for kraft pulping, a number of cooking technologies of digesters and cooking processes such as MCC, ITC, and BLI which based on the theory proposed in 1980s were developed. On the other hand, COMPACT COOKINGTM G1 and G2 cooking systems which based on the theory proposed in 1990s were also innovated. COMPACT COOKING™ G2 system can meet the requirement to, (i) build a new fiber line both for hard wood and for soft wood, (ii) increase the capacity for the existing cooking system, (iii) modify the existing cooking system for the purposes of increasing cooking yield, bleaching ability, and pulp quality as well as for the purposes of reducing energy consumption and environmental load.
