Abstract
Aspen Plus simulation for eight different chemical processes. Each simulation corresponds to a process which convert biomass, natural gas, and in some cases, nuclear energy, into either dimethyl ether (DME) or Fischer-Tropsch liquids (synthetic gasoline and diesel). Some processes contain carbon capture and sequestration (CCS) steps.

The processes may include various technologies such as biomass gasification, steam methane reforming, integrated gasification and natural gas reforming, integrated high temperature gas-cooled reactors and natural gas reforming, water gas shift reaction, FT synthesis, DME synthesis, MEA or MDEA based carbon capture, gas combustion turbines, gas cleaning, and other processing steps. Nuclear energy, when used, is integrated into the system via a high temperature helium coolant as an energy carrier from certain kinds of Gen IV nuclear reactors.

The eight processes are: BGNTL-FT (biomass-gas-nuclear-to-liquids with FT synthesis), BGNTL-FT-CCS (the same with carbon capture and sequestration), BGNTL-DME and BGNTL-DME-CCS (similar processes with DME produced instead of FT liquids), BGTL-FT (biomass-and-gas-to-liquids with FT synthesis), and BGTL-FT-CCS, BGTL-DME, and BGTL-DME-CCS similarly.
