The SM4 Mercury continuous emissions monitoring system (CEMS) provides total mercury emissions reporting for all coal-fired power plants conforming to EPA PS-12A. The CEMS features a dry catalytic converter-scrubber and dilution technology, with no risk of losing ionic mercury, and uses a gold trap with mercury detection down to picograms per cubic meter.
