How to Choose Between Rotary and Slep Activation Furnaces

Choosing the activation furnace type is the core decision of an activated carbon project. This article compares rotary and Slep furnaces across feedstock flexibility, capacity, energy consumption and investment: rotary furnaces suit continuous large-scale production of coal and wood based carbons with flexible operation; Slep furnaces use steam and flue gas dual-media activation, saving energy with developed micropores, ideal for coconut and apricot shell granular carbon. Early-stage studies should model feedstock supply, target iodine value and utility costs; a combined layout is sometimes optimal. Songrui provides investment and energy comparison studies for both types.
