Advanced Process Control Minimizes Kraft Mill Effluents

open access: yesIFAC Proceedings Volumes, 1977
Abstract In recent years the pulp industry, like any other industry, has been obliged to pay more attention to the problem of effluents. For the most part this has been necessary in order to meet legislative requirements; but the chemical and energy losses due to these effluents are in themselves considerable enough to make their minimization ...

The Influence of Chip Size Variation in the Pulping Process from Jabon Wood

open access: yesIndonesian Journal of Chemical Research
Wood is the primary raw material in the pulp and paper industry. Due to its favorable fiber characteristics, Jabon wood (Anthocephalus cadamba Miq.) is a promising fast-growing pulp and paper production species. This study investigates the effect of nine

New Agents for Kraft Process

open access: yesJAPAN TAPPI JOURNAL, 2003
The Kraft process consists of the cooking process and the bleaching process mainly. In Kraft process, the weakest point is the low of the yield of pulp in the cooking process. The kinds of quinone derivatives or polysulfide derivatives are widely used as cooking agents to improve it.“Cooking Accelerator” is the agent to accelerate the function that ...

Improving Pulping Performance as Well as Reducing Consumption and Increasing Efficiency via Microbial Consortium Pretreating Bamboo

open access: yesFermentation, 2023
The bio-refining process of bamboo is more challenging compared to wood due to its dense and stabilized complex polymer structure, as well as its abundance of degradation-resistant components. Consequently, the bio-refining of bamboo requires more energy

PACTTM process for treatment of kraft mill effluent

open access: yesWater Science and Technology, 1997
The PACTTM process (powdered activated carbon addition to the activated sludge process) was evaluated for the treatment of Kraft pulp mill wastewater in a series of bench scale experiments. Possibly due to the relatively low strength wastewater, the PACTTM process with carbon doses between 0.5 and 1.0 g/L of influent only performed marginally better ...
