- This program successfully demonstrated the key components that are needed for a practical, regenerable sorption process for removing and recovering mercury from flue gas streams: (1) a proprietary natural product removed mercuric chloride from synthetic flue gas, (2) several new noble metal sorbents were shown to capture elemental gas-phase mercury from synthetic coal combustion flue gas, and (3) both the natural product and the noble metal sorbents could be regenerated in the laboratory (chemical method for the natural product, thermal method for noble metal sorbents). Several sorbents were tested for their ability to collect selenium oxide during the program. These tests, however, were not definitive due to inconclusive analytical results. If follow-on testing is funded, the ability of the proposed sorbents to collect selenium and other metals will be evaluated during the field testing phase of the program. A preliminary economic analysis indicates that the cost of the process appears to be substantially less than the cost of the state-of-the-art method, namely injection of activated carbon, and it also appears to cost less than using noble metal sorbents alone.
