Advanced in-duct sorbent injection for SO{sub 2} control. Topical report No. 5, Task 4: Data analysis and computer modeling

PDF Version Also Available for Download.

Description

The objective of this research project is to develop a second generation in-duct sorbent injection technology as a cost-effective compliance option for the 1990 Clean Air Act Amendments. Specific performance targets are 90% SO{sub 2} removal and 60% sorbent utilization efficiency. After initial results indicated that the Advanced Coolside process had a potential of exceeding these targets, research focused on the Advanced Coolside process. For Task 4, Data Analysis and Computer Modeling, the objective was to develop two computer models. The first computer model would correlate sorbent properties with hydration parameters, while the second would correlate desulfurization performance with the ... continued below

Description

The objective of this research project is to develop a second generation in-duct sorbent injection technology as a cost-effective compliance option for the 1990 Clean Air Act Amendments. Specific performance targets are 90% SO{sub 2} removal and 60% sorbent utilization efficiency. After initial results indicated that the Advanced Coolside process had a potential of exceeding these targets, research focused on the Advanced Coolside process. For Task 4, Data Analysis and Computer Modeling, the objective was to develop two computer models. The first computer model would correlate sorbent properties with hydration parameters, while the second would correlate desulfurization performance with the sorbent properties. A two-level factorial program was undertaken to examine the effects of selected hydration process variables on some of the physical and chemical properties of the hydrates produced and on their SO{sub 2} reactivity. A bench-scale hydrator was used to convert quicklime samples to hydrated limes under controlled processing conditions. Two quicklimes were hydrated -- Mississippi Lime and Black River Lime. Significant differences in physical properties of these hydrates were observed. However, no relationship between the measured physical properties and the SO{sub 2} reactivity was observed. Within the scope of this work, SO{sub 2} reactivity is not a function of quicklime source. When compared with commercial hydrates prepared from the same quicklime, the hydrates produced in the bench-scale unit showed significantly lower surface areas and SO{sub 2} reactivities. As a result, the correlations developed in this study do not apply to commercial hydrates.
