''Hydrate Addition at Low Temperature'' or HALT is a dry calcium- based hydrate injection process for the removal of SO/sub 2/ 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 particulates. 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. The HALT test program currently being conducted at Dravo Lime Company and Ohio Edison Company is to be carried out in two stages: (1) Parametric testing on a 1.0 MM BTU/hour combustor, and (2) Follow up long term testing (six months) on a 5 MW unit. The first stage of the program which involves the parametric testing is now completed. Results are presented. 9 refs., 18 figs.
