Abstract
Regenerable mixed metal oxide sorbents are prime candidates for
the removal of hydrogen sulfide from hot gasifier gas in the
simplified integrated gasification combined cycle (IGCC) process.
As part of the regenerative sulfur removal process development,
reactor models are needed for scale-up. Steady-state kinetic
reactor models are needed for reactor sizing, and dynamic models
can be used for process control design and operator training. The
regenerative sulfur removal process to be studied in this paper
consists of two side-by-side fluidized bed reactors operating at
temperatures of 400-650°C and at elevated pressure. In this paper,
hydrodynamic modeling equations for dense fluidized bed and
freeboard are applied for the prediction of the performance of a
large-scale regeneration reactor. These equations can partly
explain the differences in modeling results observed with a
simpler model that does not account for bed hydrodynamics. The
pilot-scale test run results, obtained in the test runs of the
sulfur removal process with real coal gasifier gas, have been used
for parameter estimation. The validity of the reactor model for
commercial-scale design applications is discussed.
