| titleOfInvention | Method for separating sulfide from pulping liquid using amphoteric resin |
| abstract | (57) [Summary] The sulfide-rich component of the kraft pulping white liquor (8) is obtained by a method using an ion exchange resin, also known as a “snake cage electrolyte” resin, contained in an ion suppression separation device (9). (12) and a component (10) rich in caustic. The sulphide-rich component (12) can be used in the initial stage of pulping (1) and in the pretreatment of the wood chips prior to pulping, or it can be used to prepare a polysulfide-rich liquor. it can. The caustic-rich component (10) can be used in the final delignification stage or can be used instead of sodium hydroxide or white liquor in oxygen delignification, pH adjustment and flue gas scrubbing. it can. The same system as described above separates the green liquor (6) and the polysulfide liquor (8a) into sulphide-rich and sulphide-poor components and also sulphide from other sulphide-contaminated factory caustic streams. Can be used to remove objects. |
