PREDECTIVE EMISSIONS MONITOR SYSTEMS AND METHODS

摘要

One embodiment of the present disclosure describes an industrial system, which includes a control system. The control system includes a predictive emissions monitoring system that facilitates determining a chemical level output from a selective catalytic reduction unit that reduces the chemical level in gaseous emissions produced by a combustion source in the industrial system using a selective catalytic reduction model. The control system tunes the selective catalytic reduction model to the selective catalytic reduction unit by determining tuning parameters of the selective catalytic reduction model based at least in part on vendor information and tuning data determined via a tuning sequence. The tuning sequence includes operating the combustion source at a plurality of load levels, injecting, using the selective catalytic reduction unit, a reactant into received gaseous emissions at each of the plurality of load levels in accordance with an injection rate provided in the vendor information; and determining an input chemical level to and an output chemical level from the selective catalytic reduction unit at each of the plurality of load levels.
