“Analisis Optimalisasi Energy Consumption Pada Unit Lime Kiln #2”
ABSTRACT Recausticizing Lime Kiln is one of the areas in PT RAPP which is responsible for producing white liquor cooking liquid for wood chip cooking needs in the digester. In the process, the causticizing reaction produces a byproduct in the form of lime mud (CaCO3) which can be converted back into burnt lime (CaO). This process requires a lime kiln unit to burn lime mud so that a calcination…
