Abstract

Vid ett förfarande för kontinuerlig utfällning av lignin från svartlut - bringas svartlut att strömma i form av en tryckström i en reaktor (2) med en retentionstid av under 300 s, - leds till strömmen som eil försurningsmedel koldioxid vid ett eller flera matningsställen (2a) för att sänka svartlutens pH, - låter man pH-värdet sänka under inverkan av koldioxid till utfällningspunkt av lignin i tryckströmmen, - frigörs plötsligen tryckströmmens tryck, och - separeras ligninpartiklar från svartluten.In a process for continuous precipitation of lignin from black liquor - black liquor is made to flow in the form of a pressurized stream in a reactor (2) with a retention time of less than 300 s, - is led to the stream as an acidifying agent carbon dioxide at one or more feed points (2a) to lower the pH of the black liquor, - the pH is allowed to drop under the influence of carbon dioxide to the point of precipitation of lignin in the pressure stream, - the pressure of the pressure stream is suddenly released, and - lignin particles are separated from the black liquor.
