Abstract

La presente es concerniente con un proceso mejorado para inhibir la incrustacion de carbonato de calcio en sistemas acuosos tales como aquellos empleadosen el proceso de Kraft para la produccion de pulpa de madera. Tal proceso mejorado es obtenido mediante la adicion al sistema de por lo menos una unidadmonomérica derivada del grupo que consiste de 1,2-dihidroxi-3-buteno, N-(hidroximetil)acrilamida y N-(sulfometil)acrilamida y por lo menos una unidadmonomérica derivada del grupo que consiste deácido maléico, ácido acrílico, acrilamida, ácido metacrílico, ácido itaconico, ácido vinilsulfonico, ácidoestirensulfonico, N-terbutilacrilamida, butoximetilacrilamida, N,N-dimetil-acrilamida, ácido acrilamidometilpropano sulfonico de sodio y sales de los mismos.La presente provee además una nueva clase de agentes antiincrustantes poliméricos que son polímeros que comprenden una unidad monomérica de 1,2-dihidroxi-3-buteno y por lo menos una unidad monomérica derivada del grupo que consiste de ácido maléico, ácido acrílico, acrilamida, ácido metacrílico, ácido itaconico,ácido vinilsulfonico, ácido estirensulfonico, N-terbutilacrilamida, butoximetil-acrilamida, N,N-dimetil-acrilamida, ácido acrilamidometil-propansulfonico desodio y sales de los mismos, con la condicion de que los polímeros no contengan la unidad monomérica -(CH2-CH=CH-CH2-O)-.
