Removal of SO2From Power Plant Flue Gases Using the Alkalized Alumina Process. Phases I and II. Data Evaluation Preliminary Process Design,Optimization,and Economics.

摘要

The results of a contractual effort to correlate and evaluate data from several sources,on the development of the alkalized alumina sorbent and process are reported in two phases: Phase I -data evaluation and preliminary process design,and Phase II -process optimization studies. This report includes an analysis of available attrition data,and a summary of the attrition test methods used. The process design study includes an evaluation of;sorption chemistry,current sorption data,and sorption modeling. Regeneration reactions and evaluation of the status of the data are presented with discussion of pilot plant results,bench scale tests with reducing gases,and evaluation of various sorbents. Process description;calculations and vessel design are presented for three process designs;dispersed phase,fluid bed,and fixed bed. A stream reformer, a claus plant and a precipitator,are included for each process. A comprehensive economic analysis of the process is also included. (Author)
