Abstract

Filtrater fra bleking og delignifisering av masse resirkuleres for anvendelse ved oppslutning, separasjon og gjenvinning av lignin (66) og andre biprodukter, hvilket forer til en vesentlig energiinnsparing og unngåelse eller eventuelt eliminering av forurensing som typisk er assosiert med bleking. Oppfinnel- sen vedrører også produkter avledet fra prosessen og et apparat for utføring av prosessen. Ligniner med varierende molekylvekter og biprodukter fra oppslut- ningsprosessen blir også gjenvunnet (66). Ligninene utfelles i høye utbytter og med høy hastighet fra en svartlut (40) dannet ved oppslutning av tre ved høy temperatur og trykk. Som biprodukt ved prosessen gjenvinnes et renset furfuralprodukt (71). Dette furfural kan resirkuleres for anvendelse ved gjen- vinning av lavmolekylært lignin i foreliggende prosess.Filtrates from bleaching and delignification of pulp are recycled for use in the digestion, separation and recovery of lignin (66) and other by-products, leading to significant energy savings and avoidance or possibly elimination of contamination typically associated with bleaching. The invention also relates to products derived from the process and an apparatus for carrying out the process. Lignins with varying molecular weights and by-products from the digestion process are also recovered (66). The lignins are precipitated in high yields and at high velocity from a black liquor (40) formed by the support of wood at high temperature and pressure. As a by-product of the process, a purified furfural product is recovered (71). This furfural can be recycled for use in the recovery of low molecular weight lignin in the present process.
