DOE Grant No. DE-FG02-06ER84591
Amount: $99,902
The injection of activated
carbon into the flue gas has been shown to mitigate the emission of mercury in
all coal-fired power plants, even those with wet and dry scrubbers. This is a low-capital-cost technology in
which the largest cost element is the cost of the activated carbon sorbent. Therefore, the obvious approach to further
cost reductions is to reduce the amount of sorbent needed or to decrease the
cost of sorbent production. This project
will develop a new process for the production of sorbents that will
dramatically reduce production costs and increase production capacity in both
existing and new activated carbon production facilities. Phase I will define the processing parameters
that produce an optimized sorbent at the lowest manufacturing cost. Sample sorbent materials will be produced in
the laboratory and tested with flue gas to determine the capability for
capturing mercury. Phase II will focus
on scaling-up the manufacturing process and producing sufficient quantities of
the sorbent for use in a full-scale mercury control test at one or more
coal-fired power plants.
Commercial Applications and Other Benefits as described by the awardee: The target market for the sorbent is coal-fired power plants that need to control mercury emissions. In addition to the power companies themselves, electricity consumers should also benefit from lower electric rates, if the power plants were to use economical means to comply with pollution control regulations.
