Table 7 to Subpart U of Part 63—Operating Parameters for Which Monitoring Levels Are Required To Be Established for Continuous and Batch Front-End Process Vents and Aggregate Batch Vent Streams
Parameters to be monitored
Established operating parameter(s)
a 25 to 50 mm (absolute) is a common pressure level obtained by pressure swing absorbers.
b Concentration is measured instead of an operating parameter.
Temperature upstream and downstream of the catalyst bed
Minimum upstream temperature; and minimum temperature difference across the catalyst bed.
Boiler or process heater
Scrubber for halogenated vents
pH of scrubber effluent; and scrubber liquid and gas flow rates[§ 63.489(b)(4)(ii)]
Minimum pH; and minimum liquid/gas ratio.
Exit temperature of the absorbing liquid; and exit specific gravity of the absorbing liquid
Maximum temperature; and maximum specific gravity.
Total regeneration steam flow or nitrogen flow, or pressure (gauge or absolute) a during carbon bed regeneration cycle; and temperature of the carbon bed after regeneration (and within 15 minutes of completing any cooling cycle(s))
Maximum flow or pressure; and maximum temperature.
Other devices (or as an alternate to the above) b
HAP concentration level or reading at outlet of device
Maximum HAP concentration or reading.
