Abstract

MéTODO úTIL EM UM PROCESSO DE PRODUçãO DE POLPA DE CELULOSE QUE PRODUZ UM PRODUTO DERIVADO DE LIXìVIA Trata-se de um método para remoção de poluente de um produto derivado de lixívia de um processo de fabricação de polpa de celulose ("pulping" - polpação), em que o referido compreende a injeção de um gás contendo oxigênio na referida lixívia e a condensação do vapor de água do gás de extração de forma a produzir um condensado compreendendo poluentes.USEFUL METHOD IN A CELLULOSE PULP PRODUCTION PROCESS THAT PRODUCES A LIXID DERIVATIVE PRODUCT This is a method for removing pollutant from a bleach-derived product from a pulping pulping process. wherein said comprises injecting an oxygen-containing gas into said bleach and condensing the water vapor of the extraction gas to produce a condensate comprising pollutants.
