| titleOfInvention | Use of alkyleneamines for improving the dehydration of lime mud |
| abstract | (57) [Summary] A method for dewatering lime mud in kraft pulping is described. The method is characterized in that the lime mud comprises adding an effective amount of an alkylene amine prior to filtration. Preferred alkylene amines are ethylene amines, i.e., at least one - (CR 2 -CR 2 -NH - ) - unit wherein each of R, independently, has a H or from 1 to 10 carbon atoms Alkyl (linear, branched or cyclic) group]. Examples of ethyleneamines include ethyleneamine mixtures such as ethylenediamine, diethylenetriamine, triethylenediamine, triethylenetetramine, tetraethylenepentamine, piperazine, aminoethylpiperazine and mixtures of ethyleneamine oligomers having an average molecular weight of about 200-500.
