Abstract
This work deals with techno-economic analysis studies in the context of production of various grade biocarbon for utilization as reducing agents in metallurgical industries. A detailed process design was developed for wood handling, debarking, chipping, drying, carbonization, and combined heat and power production using Aspen Plus for 10 ton per day (TPD) biocarbon output. A Fortran based user defined function was developed for the carbonization process by considering pressure, temperature and particle size effects using a Box–Behnken approach. The empirical correlation indicates a strong influence of temperature as well as a significant influence of pressure and particle size on the biocarbon yield and its fixed carbon content. Fixed carbon content increases with temperature, pressure, and particle size. Mass and energy balance results from Aspen Plus provided necessary results for cost parametrization considering three influencing parameters: temperature, pressure, and plant scale on the equipment costs...
