We also evaluated the impact of different levels of syngas
compression pressure (1.0, 1.5, 2.0, 2.5, and 3.0 MPa) to the gas
turbine. Syngas compression pressure of 1 MPa requires two
compression stages, while the higher pressures require three
compression stages [29e32]. We found that 1 MPa (2 stage)
compression and 2 MPa (3 stage) compression provided the
best combinations of performance so we have chosen gas
compression pressures of 1 and 2 MPafor further comparisons.
