| Abstract: | This study focuses on energy optimization in evaporator
and digester of integrated pulp and paper mills in India, and recommends application of 7 effects/plates evaporator
in place of 5 effects/plates normally used. Steam economy resulting from this modification is definitely more than 7. Pinch
technology is found suitable for optimization of controlled parameters in the digester. Using recommendations, total energy savings
was observed in West Coast Paper Mill (11.74%) and Star Paper Mill (12.97%). Environmental benefits that will accrue in
terms of reductions in emissions are: SPM, 46464-48664 TPA; SO2 , 1045 kg/annum; H2S, 55,020
kg/annum; and CO2, 13612 TPA. |
