Techno-economic evaluation of biomass-to-synthesis gas (BtS) based on gasification

Gasification is a thermochemical process to produce a clean syngas with low emissions and high caloric value (4.0–22.0 MJ/N m³) compared to other thermal processes. In this research work, an Aspen Plus/Icarus model used to evaluate the techno-economic aspects of gasification process to convert the biomass particles into syngas. Results showed as the plant size increases the DCFROR and ROI increases; however, a reverse impact obtained for PBP. It is also found the gasification of small-size particles plays a major role in the process; smaller particle size is affordable compared to the larger particle size. Although the present model used for techno-economic evaluation of biomass gasification, it can be used as a general model to study the economic aspects of gasification process for other feedstocks such as oil, coal, and municipal solid wastes.
