chemical introduced in the recovery boiler and is carried through the recausticizing system and liquor cycle as dead load. There are other chemicals such as sodium sulfite (Na2SO3), sodium thiosulphate (Na2S2O3), iron, manganese, silica, and aluminum to name a few1. These generally are not troublesome unless the system is not designed with a means
