Pengaruh ClO2 Strenght terhadap Brighness Pulp di Menara Khlorin Dioksida pada Unit Bleaching Plant di PT Toba Pulp Lestari, Tbk Porsea

Abstract

Effect of ClO2 strenght to pulp brightness in tower of chlorine dioxide at unit of bleaching plant is whitening of first phase, begining from brown pulp become to turn white with usage ClO2 flow 1 and 2 in liter per minute with consistency of pulp equal 5%. Result of obtained solution that effect of ClO2 strenght for gift which not uniform, value (rate) progressively increase will have an effect on to make-up of number degree of brightness pulp. In determination of line equation of regresi obtained relation of Y = 6.5 + 0.001(60) at brightness 42.4o based on ISO. At uniform gift, value (rate) do not increase (constant), but make-up of number degree of brightness pulp progressively mount. In equation of line of regresi obtained by relation of Y = 7 + 0(60) at brightness 47.6o based on ISO. Attainment of number degree of brightness which is not optimal will effect the amount of usage of chlorine dioxide in phase here in after to reach brightness according of International Standart of Organization (ISO).
