In the diagram above of a precalciner kiln, raw meal passes down the preheater tower while hot gases rise up, heating the raw meal. At 'A,' the raw meal largely decarbonates; at 'B,' the temperature is 1000 C - 1200 C and intermediate compounds are forming and at 'C,' the burning zone, clinker nodules and the final clinker minerals form.

Treatment of Raw Palm Oil Mill Effluent (POME) A palm oil mill produces an average of 0.65 tons of raw palm oil mill effluent (POME) from every ton of FFB processed. POME is the main cause of environmental pollution due to its high acidity, high biological oxygen demand (BOD) and chemical oxygen demand (COD).
