Abstract:
1. A system for treatment of an effluent material, said system comprising: an inlet conduit arranged to receive the effluent material from an upstream processing unit; a sampling region for the effluent material in flow communication with the inlet conduit, the sampling region defining a radiation transmission path; an infrared radiation source constructed and arranged to emit infrared radiation into the sampling region; and a thermopile detector constructed and arranged to receive at least a portion of the infrared radiation following passage thereof through the sampling region, and arranged to responsively generate an output signal correlative of at least one of (i) effluent material composition and (ii) concentration of an abatable component of the effluent material within the sampling region; and a control element arranged to receive the output signal from the thermopile detector and arranged to control an effluent abatement apparatus, based on the received output signal to maintain effluent material and/or abatable component discharge below a predetermined level.
