Comparing the cooking system was done by studying mill data and analyzing the sample. Post  O2  pulp  produced  from  SuperBatch  and  CompactCookingTM  G2  were  bleached  in laboratory scale with two different sequences, D0-EOP-D1-D2  and DHot-EOP-D1.  In the bleaching, there are three different kappa factors applied; 0.25; 0.30 and 0.35. The  mill  data  shows  that  CompactCookingTM  G2  gives  lower  power  and  energy  in operation    and    also    better    yield    than    SuperBatch.    In    term    of    pulp    quality, CompactCookingTM   G2   presented   higher   kappa   number   and   viscosity   but   lower hexenuronic acid.  The laboratory bleaching result shows that even SuperBatch has lower kappa  number  but  it  gives  higher  bleachability  than  CompactCookingTM  G2  pulp.  This study also proven that D2 stage did not give significant brightness gain in final brightness therefore it can be omitted to save energy and chemical consumption. The  papermaking  potential  of  pulp  produced  from  laboratory  experiment  gives  similar response.  Both  pulp  shows  similar  strength  and  optical  properties.  Hence  the  mill  sample shows that SuperBatch still gives better strength properties than CompactCookingTM G2 0aAcacia 0aWood-pulpxBleaching 0aKraft paper industry1 aBharti, Shashank,eChairperson1 aNazhad, Mousa M.,eExamination Committee0 aSawitree Pisuttipiched,eExamination Committee2 aAPRIL - PT.
