Umzila wokukhiqiza ukupheka okwenziwa ngokuzimela kwe-China Paper Industry usetshenziswe ngempumelelo eChina Paper Industry.

Muva nje, iYueyang Forest Paper Energy Conservation and Emission Reduction Project, umugqa wokukhiqiza ukupheka okwenziwa ngokuzimela kwe-chemical pulp displacement, oxhaswe yi-China Paper Group, uqaliswe ngempumelelo ukusebenza. Lokhu akugcini nje ngokuba yintuthuko enkulu ekusungulweni kwezobuchwepheshe kwenkampani, kodwa futhi kuwumkhuba obalulekile wokukhuthaza ukuguqulwa nokuthuthukiswa kwezimboni zendabuko ngokukhiqiza okusha kwekhwalithi.
Iphrojekthi yokukhiqiza umugqa wokupheka othuthukiswe ngokuzimela wamakhemikhali okhiqizwa ezweni lonke iyiphrojekthi ebalulekile yokonga amandla, ukuvikelwa kwemvelo, kanye nokuthuthukiswa kwekhwalithi ekhuthazwe yiYueyang Forest Paper. Yavunywa ngokusemthethweni ngoJanuwari 2023. Ngokubambisana okuseduze nezinkampani zokonga amandla kanye nokuvikelwa kwemvelo, impumelelo kwezobuchwepheshe bocwaningo kanye nokusetshenziswa kwezimboni kwale phrojekthi ifinyelelwe.

Ukupheka kokususwa kwe-pulp yamakhemikhali kunezici zokusebenza kahle kakhulu nokonga amandla. Ngokusebenzisa imisebenzi eminingi yokususwa kwe-pulp, ukuhamba kwayo kwenqubo akugcini nje ngokubuyisa nokusebenzisa ukushisa okulahliwe kanye nezidakamizwa ezisele kusukela ekuphekeni kwangaphambilini, kodwa futhi kuvuselela ikhambi lokupheka lokushisa eliphezulu ekupheleni kokupheka, kunciphisa ngempumelelo ukusetshenziswa kwamandla kanye nomthamo wamakhemikhali. Uma kuqhathaniswa nenqubo yokukhiqiza yokupheka yendabuko ngezikhathi ezithile, lobu buchwepheshe bunciphisa kakhulu ukusetshenziswa komusi namanzi ngethani le-pulp, kufezwa amazinga aphezulu okukhishwa kwemvelo. Ngesikhathi esifanayo, ikhwalithi ye-slurry ekhiqizwa ngale nqubo yokukhiqiza iphakeme, futhi opharetha abadingekayo bancishiswa ngo-50%, okuzothuthukisa kakhulu ukusebenza kahle kokukhiqiza kanye nezinzuzo eziphelele.
