Pengaruh Penambahan Naoh di Dalam White Liquor terhadap Bilangan Kappa dan Viskositas Pada Pemasakan di Unit Digester PT. Toba Pulp Lestari,Tbk Porsea

Abstract

Observation has been done on the effect of the addition of NaOH in the white liquor to the kappa number and viscosity cooking in the digester. Sampling was done 14 times in a few days with a range of observation time every 2 hours. Limit the addition of NaOH were good for cooking in the digester about 69,9 g/l – 86,0 g/l. From the observations have results that amount of addition NaOH used in cooking in the digester is inversely related to the results of the kappa number and viscosity values.
