| titleOfInvention | Use of alkyleneamines for enhancing lime mud dewatering |
| abstract | A process for dewatering lime mud in a kraft pulping process is described. T he process includes an improvement which comprises adding an effective amount o f an alkyleneamine to the lime mud prior to filtration. The preferred alkyleneamine is ethyleneamine, that is, an amine having at least one -(CR2- CR2-NH-)- unit wherein each R independently is H or an alkyl (straight, branched or cyclic) group of from 1 to 10 carbon atoms. Ethyleneamines inclu de ethylenediamine, diethylenetriamine, triethylenediamine, triethylenetetramin e, tetraethylenepentamine, piperazine, aminoethylpiperazine, and ethyleneamine mixtures such as mixtures of ethyleneamine oligomers having an average molecular weight of about 200-500. |
