Fa'aaogaina o le Oloa

NHDo se ituaiga fou e maualuga le aoga o le de-sulfurizing ma le de-carbonating solvent e maualuga le mama, sili ona lelei le kemisi ma le tumau i le vevela i ala o mea e maualuga le acidity, alkality ma le vevela. E talafeagai mo le faʻamamāina o le kesi anthraco-synthetic. E mafai ona faʻamamā lelei le hydrogen vulcanized mai le paluga o le kesi acid o le kesi masani, kesi o le fanua suauʻu, kesi malala i falegaosimea poʻo taulaga ma le kesi penisini ua liquefied. Ae maise lava, e mafai ona faʻamamā lelei le sulfur organic sulfur.
