Abstract
An entrainedflow system has been designed and constructed to simulate inflight mercury capture by sorbents in ducts of coalfired utility plants The test conditions of 15 s residence time 140°C temperature 45 ppbv inlet Hg0 concentration and 0–20 lb/MMacf sorbent injection rates were chosen to simulate conditions in the ducts Novel oxidants developed in previous fixedbed tests and novel sorbents derived from the novel oxidants were tested for their Hg0 capture in the entrainedflow system to examine the possibility of using those sorbents in a fullscale system DarcoFGD and Darco HgLH served as benchmark sorbents with which mercury control capability of the novel oxidants and novel sorbents could be compared The test results showed that the novel oxidants have remarkable Hg0 oxidation capability and the novel sorbents showed a better performance in Hg0 removal than Darco HgLH
