Novel process for removal and recovery of vapor-phase mercury. Monthly technical progress report, November 1--November 30, 1995
The purpose of this project is to investigate the application of a sorbent-based process for removing and recovering mercury in the flue gas of coal-fired power plants. The process is based on the sorption of mercury by noble metals and the regeneration of the sorbent by thermal means, recovering the desorbed mercury as liquid, elemental mercury. ADA Technologies holds a patent on this process (US 5,409,522, April 25, 1995) and has tested it under conditions typical of municipal waste incinerators. In this process, the noble metal sorbent is regenerated thermally, and the mercury is recovered for commercial recycle. Consequently, ADA has adopted the name ``Mercu-RE`` to describe its process. In the current project, ADA will test its process under conditions typical of coalfired power plants where the mercury concentration is low (below 10 {mu}g/m{sup 3}) and little pressure drop can be tolerated. Methods of accommodating the Mercu-RE process to the circumstances and conditions of coal-fired power plants will comprise the core of the planned program. We began to assemble the sorbent configurations to be tested. Orders were placed for the substrate materials for three of the four configurations: ceramic monoliths, metallic monoliths, and the bag filter.
