You must use the procedures and test methods in this section to determine capture efficiency as part of the performance test required by § 63.4340 or § 63.4350 .
Where:
TVHapplied = Mass of liquid TVH in regulated materials applied in the web coating/printing or dyeing/finishing operation during the capture efficiency test run, kg.
TVHi = Mass fraction of TVH in regulated material, i, that is applied in the web coating/printing or dyeing/finishing operation during the capture efficiency test run, kg TVH per kg material.
Mi = Total mass of regulated material, i, applied in the web coating/printing or dyeing/finishing operation during the capture efficiency test run, kg.
n = Number of different regulated materials applied in the web coating/printing or dyeing/finishing operation during the capture efficiency test run.
Where:
CE = Capture efficiency of the emission capture system vented to the add-on control device, percent.
TVHapplied = Total mass of TVH liquid input applied in the web coating/printing or dyeing/finishing operation during the capture efficiency test run, kg.
TVHuncaptured = Total mass of TVH that is not captured by the emission capture system and that exits from the temporary total enclosure or building enclosure during the capture efficiency test run, kg.
Where:
CE = Capture efficiency of the emission capture system vented to the add-on control device, percent.
TVHcaptured = Total mass of TVH captured by the emission capture system as measured at the inlet to the add-on control device during the emission capture efficiency test run, kg.
TVHuncaptured = Total mass of TVH that is not captured by the emission capture system and that exits from the temporary total enclosure or building enclosure during the capture efficiency test run, kg.
