This paper reviews the latest Mer-Cure? product research and development initiatives, and also provides results from a recent (March 2012) utility field test campaign using an improved version of the Mer-Cure? on-site processor technology. Mer-Cure? utilizes a patented system of on-site processing and injecting of commercially available, powdered activated carbon products into a boiler's flue gas stream, upstream of the air heater, to capture mercury released during the process of coal combustion. Testing of this new approach to the Mer-Cure? processor, which dramatically reduces the CAPEX and OPEX of the current commercially available Mer-Cure? system, was performed at a customer site using a self- contained mobile test rig. This was developed to store, process, and inject sorbents at full scale so that results can meaningfully reflect performance expectations with subsequent commercial operation of a mercury control system. This paper will describe the equipment changes in this substantial improvement to the current system, report field test data that compares the improved system performance to past performance, and document the advantages the new system has when utilities consider their options for EPA MATS compliance.
