Generally, although the wet processes are more energy intensive due to the evaporation of high moisture contained in raw materials, the investment cost of those plants is rather low and highquality products are manufactured easily [1216].On the other hand, the plants based on the dry processes consume less energy, which results in much lower operational costs of manufacturing.

Typically the bagasse moisture can be reduced from 50% to 45%. A dryer handling 90TPH through put of wet bagasse at 50% initial moisture can be dried to around 86TPH of bagasse at 45% outlet moisture with around TPH of evaporated moisture. The dryer would consume around tons of low pressure steam.

However, a number of different SP kilns are available. Most common SP kilns have between 4 and 6 cyclone stages. The moisture content of the raw materials determines the number of stages. Where moisture is less than %, a PH kiln with 4 to 6 stages may be used. The higher the number of cyclone stages, the more the heat recovered.
