5-MW Toronto HALT (Hydrate Addition at Low Temperature) Pilot Plant Testing: Appendices: Part 1-B.

摘要

''Hydrate Addition at Low Temperature'' or HALT is a dry calcium-based hydrate injection process for the removal of SO2 from flue gases off a sulfur bearing fuel. In this process the hydrate is pneumatically conveyed and injected into the flue gas stream as a dry particulate. The flue gas is cooled downstream of the hydrate injection location by spraying the gas with a stream of finely atomized water droplets. The water is atomized into a fine spray mist by using air under pressure as the atomizing fluid. The waste product from this process is the dry disposable solids which differ considerably from the wet cake solids obtained from a wet FGD process. This report contains appendices of pilot plant testing in the following areas: (a) figures (data as collected at 10 minute intervals), and inlet SO2, O2, and gas temperature variations, (b) raw data (sample), (c) solids analysis (hydrate, baghouse solids, and ESP Solids), (d) selected analytical methods on (1) microtrac procedure, (2) BET surface area measurement, (3) DuPont photometric SO2 analyzer, and (e) corrosion test data.
