Abstract

1 / 1 resumo “mã‰todos para remoã‡ãƒo de polpa a partir de madeira e recuperaã‡ãƒo de produto quãmico de formaã‡ãƒo de polpa a partir de licor negro, e para a recuperaã‡ãƒo de produtos quãmicos de formaã‡ãƒo de polpa de madeira a partir de licor negro” em um digestor, as lascas de madeira e o licor branco sã£o combinados e cozidos sob pressã£o para a formaã§ã£o de polpa da madeira. isto produz licor negro que ã© concentrado e queimado em uma caldeira de recuperaã§ã£o. a caldeira de recuperaã§ã£o produz cinzas que contã©m sã³dio, enxofre, potã¡ssio e cloreto. a cinza ã© dissolvida e submetida a um processo que recupera sulfato de sã³dio e burkeite. a concentraã§ã£o de potã¡ssio e cloreto ã© reduzida, pelo menos em parte, por sujeiã§ã£o da cinzas a um resfriamento adiabã¡tico em um cristalizador que produz glaserita e uma corrente de purga rica em cloreto. por lixiviaã§ã£o da glaserita, sulfato de sã³dio ã© removido a partir da glaserita, deixando o sulfato de potã¡ssio. o sulfato de sã³dio e burkeite recuperados podem ser reciclados e usados como produtos quã­micos de formaã§ã£o de polpa. cloreto e potã¡ssio removidos podem ser ainda tratados de forma adequada ou descartados.
