The increased measurement frequency fulfills all pulping process control needs and safely provides the genuine pulp Kappa number in dedicated process stage applications from unbleached brown stock pulp to oxygen delignification
," says Risto Rinne, Fiberline Analyzer Business Manager, Valmet.
The application of organosolv delignification
in chemical pulping has received the most attention.
Alkali and enzymatic delignification
of sugarcane bagasse to expose cellulose polymers for saccharification and bio-ethanol production.
Chemical and morphological characterization of sugarcane bagasse submitted to a delignification
process for enhanced enzymatic digestibility.
Study of delignification
of Eucalyptus urophylla hybrid by the kraft process for production of cellulose.
In order to break down the lignocellulosic bonds and to increase bioavailability of nutrients, various physical and chemical delignification
methods have been examined in agricultural co-products such as rice and wheat straw .
Furthermore, large variety of potential substrates has raised interest in the use of laccases in several industrial applications, such as pulp delignification
, textile dye bleaching, effluent detoxification, biopolymer modification and bioremediation [11,12] (Gianfreda et al, 1999; Xu, 1999).
For instance, ALMEIDA (2003) stated, that the extractive and lignin content of the wood had a direct influence on the alkali consumption, yield and delignification
rate, enabling the determination of the potential of a raw material for cellulose pulp production.
In conjunction with the expansion, Fibria plant requires another 160 tons per day of oxygen, for use in the pulp delignification
stage, also known as pre-bleaching pulp.

ABSTRACT: The present study was conducted to analyze the effect of three different organic solvents (Ethanol, Methanol and Acetone) on delignification
of rice husk (basmati rice).
The new patent covers a system and method for oxygen-assisted delignification
of lignocellulosic biomaterials and lignin recovery, which further improves the quality of the pulp produced by the AST Organosolv pulping process.
