- Table 23 to Subpart UUU of Part 63—Operating Limits for Inorganic HAP Emission Limitations for Catalytic Reforming Units
As stated in § 63.1567(a)(2), you shall meet each operating limit in the following table that applies to you.
| For each applicable process vent for a new or existing catalytic reforming unit with this type of control device . . . | You shall meet this operating limit during coke burn-off and catalyst rejuvenation . . . | 1. Wet scrubber | The daily average pH or alkalinity of the water (or scrubbing liquid) exiting the scrubber must not fall below the limit established during the performance test; and the daily average liquid-to-gas ratio must not fall below the limit established during the performance test. | 2. Internal scrubbing system or no control device ( | The daily average HCl concentration in the catalyst regenerator exhaust gas must not exceed the limit established during the performance test. | 3. Internal scrubbing system meeting HCl percent reduction standard. | The daily average pH or alkalinity of the water (or scrubbing liquid) exiting the internal scrubbing system must not fall below the limit established during the performance test; and the daily average liquid-to-gas ratio must not fall below the limit established during the performance test. | 4. Fixed-bed gas-solid adsorption system | The daily average temperature of the gas entering or exiting the adsorption system must not exceed the limit established during the performance test; and the HCl concentration in the adsorption system exhaust gas must not exceed the limit established during the performance test. | 5. Moving-bed gas-solid adsorption system ( | The daily average temperature of the gas entering or exiting the adsorption system must not exceed the limit established during the performance test; and the weekly average chloride level on the sorbent entering the adsorption system must not exceed the design or manufacturer's recommended limit (1.35 weight percent for the Chlorsorb TM System); and the weekly average chloride level on the sorbent leaving the adsorption system must not exceed the design or manufacturer's recommended limit (1.8 weight percent for the Chlorsorb TM System). |
