Iron Thiochelate
Iron Thiochelate is a more recent development addressing NOx and SOx removal. The catalyst is added to the limestone in wet scrubbers to absorb NO. The catalyst is then regenerated as the bound NO is reduced to ammonia by electrochemical reduction. [See Nature, v. 369, 12 May 94, p. 139.] In mid May 95, a patent application was filed for a new simpler reduction technique, in which the liquor is passed through a column of Fe chips.
WANTED: a demo host, slip stream or pilot scale.
