Abstract

"PROCESSO PARA CONTROLE DE DEPóSITOS RESINOSOS (PITCH) EM PLANTAS DE PRODUçãO DE CELULOSE BRANQUEADA E NãO BRANQUEADA COM ADSORVENTES MINERAIS DEFLOCULADOS CAMPO DE APLICAçãO". Que se baseia na ação sinergética de um dispersante orgânico e de uma carga mineral, onde o dispersante mantém sob controle diversos cátions presentes no meio, os quais, uma vez livres, provocam a deposição das resinas, ao passo que a carga mineral tem a função de adsorver as resinas remanescentes, permitindo assim o controle e a inibição da deposição de resinas sobre as fibras celulósicas e sobre os equipamentos utilizados na sua produção."PROCESS FOR CONTROL OF RESIN DEPOSITS (PITCH) IN BLANKED AND UNCHANKED CELLULOSE PRODUCTION PLANTS WITH DEFLOCULATED MINERAL ADSORVENTS APPLICATION FIELD". Which is based on the synergistic action of an organic dispersant and a mineral filler, where the dispersant keeps under control several cations present in the medium, which, once free, cause the deposition of resins, while the mineral filler has the function adsorbing the remaining resins, thus allowing the control and inhibition of resin deposition on the cellulosic fibers and on the equipment used in their production.
