Abstract |
Processes for the removal of SO2 from power plant flue gases were studied. Process models were developed for fluid bed and transport reactor gas-solid contacting. Using the process models, the economics of the two types of processes were compared, and operating and capital costs estimated. Also, the kinetics of the sorption process were measured and found to be pore diffusion controlled over most of the possible range of sorbent loadings. A rate model describing the sorption process was developed. The rates of regeneration of spent sorbent were also measured. The kinetic data were used as inputs to the process models described above.
