Muva nje, i-Yueyang Forest Paper Energy Conservation and Emission Reduction Project, ulayini wokukhiqiza wamakhemikhali othuthukiswe ngokuzimela osungulwe ekhaya, oxhaswe yi-China Paper Group, uqaliswe ngempumelelo. Lokhu akukona nje ukuphumelela okukhulu ekusungulweni kwezobuchwepheshe benkampani, kodwa futhi kuwumkhuba obalulekile wokuthuthukisa uguquko nokuthuthukiswa kwezimboni zendabuko ngokukhiqiza okusha kwekhwalithi.
Iphrojekthi yomugqa wokupheka wokukhishwa kwamakhemikhali othuthukiswe ngokuzimela iwukhiye wokonga amandla, ukuvikela imvelo, kanye nephrojekthi yokuthuthukisa ikhwalithi ekhuthazwa yi-Yueyang Forest Paper. Yavunywa ngokusemthethweni ngoJanuwari 2023. Ngokusebenzisana eduze nezinkampani ezonga ugesi nezokuvikela imvelo, impumelelo kubuchwepheshe bocwaningo nokusebenzisa le phrojekthi ezimbonini kufinyelelwe.
Ukupheka kwe-chemical pulp displacement kunekhono eliphezulu nezici zokonga amandla. Ngemisebenzi eminingi yokuthutha, ukugeleza kwayo akukwazi nje kuphela ukubuyisela futhi kusebenzise ukushisa okulahlwayo kanye nezidakamizwa ezisele ekuphekeni kwangaphambilini, kodwa futhi kuphinde kusetshenziswe isisombululo sokupheka esisezingeni eliphezulu ekupheleni kokupheka, kwehlisa ngempumelelo ukusetshenziswa kwamandla kanye nesilinganiso samakhemikhali. Uma kuqhathaniswa nenqubo yokukhiqiza yokupheka okuvamile, lobu buchwepheshe bunciphisa kakhulu ukusetshenziswa kwesitimu namanzi ngethani ngalinye le-pulp, kufinyelele amazinga aphezulu okukhishwa kwemvelo. Ngesikhathi esifanayo, ikhwalithi ye-slurry ekhiqizwa ngale nqubo yokukhiqiza iphakeme, futhi opharetha abadingekayo bancishiswa ngo-50%, okuzokwenza ngcono kakhulu ukusebenza kahle kokukhiqiza kanye nezinzuzo eziphelele.
