Black liquor, the lignin-rich byproduct of kraft pulp production, is burned
in boiler/steam turbine cogeneration systems at pulp mills today to provid
e heat and power for onsite use. Black liquor gasification technologies und
er development would enable this fuel to be used in gas turbines. This pape
r reports preliminary economics of 100-MWe scale integrated black-liquor ga
sifier/combined cycles using alternative commercially proposed gasifier des
igns. The economics are based on detailed full-load performance modeling an
d on capital, operating and maintenance costs developed in collaboration wi
th engineers at Bechtel Corporation and Stone & Webster Engineering. Compar
isons with conventional boiler/steam turbine systems are included.
