public class GasificationSynthesisModule extends ProcessModule
Pre-built biorefinery module for biomass gasification and Fischer-Tropsch synthesis.

Composes a BiomassGasifier, syngas cleanup (tar removal, cooling), and a simplified Fischer-Tropsch (FT) reactor into a complete biomass-to-liquids process. The module takes a biomass feed stream and produces a synthetic liquid product and tail gas.

The internal process is:

  1. Biomass gasification to produce syngas (CO, H2, CO2)
  2. Syngas cooling and tar/particulate removal
  3. Fischer-Tropsch synthesis: CO + 2H2 → -CH2- + H2O (simplified stoichiometry)
  4. Product separation (liquid hydrocarbons + tail gas)
